Preventing Shootings: Is Gun Control the Answer?
When I heard about the shooting last Friday in Connecticut, I was devastated. Not only were there many victims but the majority were young children. No matter what a person is thinking or what’s going on in their head, children should be off limits. Right now, the whole country is in shock and everyone agrees to what we all really knew a long time already: something has to change. That is whether you’re pro guns or against guns.
Right after the tragedy, social media posts started pouring in with anger, shock and different messages. One of them was that guns should be banned. What you’ll read further in this article is simply thoughts from me, it’s not meant to be confrontational whatsoever. After all, gun control is an extremely heated topic.
As a native Belgian, I have some thoughts about the issue that may or may not be right. However, there are certain things that I have picked up and I am also able to compare different policies. First of all, let me address what the policy is like in Belgium.
Any adult and 16-18 year old (with approval from parents) is allowed to possess a firearm. I personally had my first firearm when I was 17 years old. The process isn’t easy and there are many restrictions. I had never seen a semi automatic rifle until I came to the US, but Belgium doesn’t have the expansive nature and predators either. When you want a firearm, you have to pass a safety test in the shooting range, as well as an interview with the local sheriff. There are also background checks, you are obligated to be part of a shooting range for the duration you possess your firearm and the police is allowed to make a home visit and make sure that the firearm is safely locked away in a safe.
That raises the question, what can we adopt from this policy? Perhaps that the tests and background checks are more thorough and expansive. You can’t just walk in a store and walk out after a quick check with a firearm. Maybe firearms should be required to be locked in a safe and police can come and check on that. That only might have prevented Adam Lanza of getting his hands on his mothers weapons.
I like firearms. I consider them valuable for sport shooting (target shooting, I don’t hunt personally) and for home defense. If it meant it would resolve all these issues with shootings and people hurting each other, I would gladly give them up. However, it would not be the solution. After all, it’s people hurting people. If they are motivated, they will find other ways unfortunately. That doesn’t mean that we can’t do anything about the law, purchasing process, requirements and background checks though. We can make sure it’s harder for individuals to get them. I personally have nothing to hide and applaud a stricter and slower purchasing process. It might be enough to demotivate certain other individuals who are out to do harm. On the other hand, would this increase the number of firearms on the black market? I don’t know.
When clients ask me about weapons for self defense, I always tell them it can be either really helpful or it can be used against them. That is why it’s a completely personal decision. As with any weapon, you need to know how to use it in a safe way instead of making things more dangerous for yourself or others. Maybe everyone who wants to purchase a firearms should follow a mandatory class which discusses their legal obligations and safety procedures?
Nobody can disagree with the fact that more needs to be done for mental health research and helping patients. There should be a database in which doctors (not only law enforcement) can share their concerns. As it is now, many mentally unstable people can still purchase firearms if there have been no previous charges against them. That is something that needs a major change.
Another topic is the assault weapons ban. After doing some research, I figured out the assault weapons are weapons that have certain requirements such as having military style and/or cosmetic features, as well as having high capacity magazine holders.
As you may already know, full automatic weapons have no place in the general population and are thankfully heavily restricted. The problem with an assault weapons ban is that so many firearms aren’t considered assault weapons but can still do the same damage. There are an extraordinary amount of semi automatic weapons out there and many or most owners will not give these up. It would be very doubtful the government would ever ask them to as any law would not be retroactive anyway. This means that all weapons already in circulation stay there, it only restricts manufacturing and possession going forward. Whether the ban from 1994 - 2004 (banning only certain firearms) worked is up for debate. But keep in mind that the tens of millions of weapons and magazines under the ban stayed in circulation.
I don’t want to get too much into the topic of banning firearms because it’s such a controversial topic. I personally don’t believe the biggest problem is gun control or possession. After all, let’s say you take them all away. The black market ‘criminal’ guns will still be out there. People can’t defend themselves against criminals, predators etc.
Saying that the world is safe enough now and we don’t need guns is incorrect in my belief. Things happen every day all over the map. There are carjackings, homejackings, violent assault, burglaries etc. Take a look at the 2011 riots in London and talk to the people who were stolen from, assaulted and whose residences were lit on fire. History tells us the world is not as stable as everyone wants it to be.
I don’t think there is a definitive answer to the problem, at least not for gun control. I think responsible owners should have the right to possess a firearm for home defense, hunting and sport shooting. I don’t think people should judge others for possessing a firearm as long as they are responsible. I don’t think it makes me look any cooler to have them and I don’t brag with it. It does make me feel safer and I enjoy going to the range every once and a while.
Besides the possibility of banning certain features and making the process stricter and more thorough, there are still a few other issues that have a direct influence to the problem:
- The media needs to stop making lists of who was the deadliest, the most devastating etc. That only motivates other individuals who are out to do harm and want to beat that number. It gives them ideas. Let’s please focus on the victims and how we can solve the problem, not indirectly make it seem like we praise this monster. Of course it’s human curiosity to find out who he was and why he did it but you can see my point.
- Mental health research and guidance (after diagnosis). Many people out there need help and if they got it, they wouldn’t do actions such as these. This is a hard goal to reach but imagine how much heartache we can prevent if we can catch a tendency or unstable temperament etc. in individuals. I don’t know much about the topic so refrain from making it seem like I’m an expert but a better safety net is necessary. Why not have a system in which doctors can ring the alarm bell?
- Why not have security people or a few police officers in institutions (schools, hospitals etc.)? This requires funds and time but also creates jobs right?
- Change the mentality of the population. Violence is put too much in the spotlight. Not everything has to be bigger, better, more violent and aggressive. There is much violence in the media, Hollywood and video games. Why not put the focus on something less destructive?
Our thoughts are with the survivors and the victims’ families. These tragedies happen too much and shouldn’t.

You Get What You Work For
When I was a kid, my parents taught me early on how to take responsibility seriously and work hard. I started drying dishes, vacuuming the floors and dusting real early on in my life. When I was 8 years old, my parents did a kitchen remodel (extension) and my sister and I brought in all the broken bricks by hand for the foundation, as well as all the bricks to build the extension.
As a teenager, I had vacation jobs from picking out fish in the factory, drying dishes in a restaurant, metal work to planting corn by hand. No matter if I knew how to do something or not, I was eager to learn and willing to make up for my lack of knowledge by hard work and motivation.
Up until this day, that lesson has stuck with me and as a business owner or athlete, if I have a goal I will not be outworked.
That doesn’t mean I’ve been successful with everything in my life, absolutely not. As a competitive biker I had a good run but didn’t have what it took (mentally) to turn pro. I have lost tournaments, failed on personal goals and have disappointed people. For these things I take full responsibility and am sorry. However I do not blame others for my shortcomings.
It is the exact way with training. If you want to reach a goal but don’t make a change, nothing will happen. If you have a 1,000 excuses all the time, nothing will happen. If you seem comfortable with how things are and don’t show motivation, nothing will happen. And if you feel sorry for yourself, it’ll be damn hard to reach that goal. This might seem blunt but it is the truth. If you want to be successful in reaching your goal and see a change, you have to look at yourself first. Keep yourself accountable for the changes you have or haven’t made, see what you can do better and don’t be satisfied with how you do things right now. If you are successful and see results in your training, there wouldn’t be a need to make changes because you are already doing a great job.
Now this doesn’t work for everyone, some individuals have other situations and should be more confident in themselves to reach a goal. However, for many this does apply. My job as a trainer is to know how to motivate someone, know who to make them reach their goal and make them feel good doing it. I highly believe in positive reinforcement and challenging a client while giving them a successful feeling when accomplishing their goals. It could be a small as an exercise or as big as a weight loss goal in 4 months from now. I don’t find it necessary to be overly strict with my clients as they are doing a great job and are intrinsically motivated. But there are also many others who need more accountability. If you want your physical goals to happen, you have to be mentally prepared. It is a huge factor in sports and training. Set little goals and go for them. Obviously things happen and your results might be off but don’t use too many excuses. If you reach a lot of little goals, you will eventually reach your final big goal.

How I Have Prevented Injuries
Sometimes, I find it easiest to write a blog post about my own experiences. It makes me write about not only the practical side of the topic but also how it effects other things such as your motivation, results and many others.
I have been wanting to write for a while about injury prevention. It’s a topic I have written about before and this will probably not be the last one either.
Injury prevention is something I find extremely important, both as an athlete and as a trainer. Safety is always my number one priority when training clients. Sometimes this gets tricky because a trainer has to push the client to get most out of the session and get the results they want. However, it needs to be done in a safe way. After all, if you get injured, you will be out for days, week, months or in some cases even years! Whatever you were doing at that point in time, was probably not worth this kind of injury.
When I train my clients, whether it’s a private session or group class, I always tell them that form should be their main focus. If they do cheat but it does not affect their safety or risk of injury, I will let them finish and then tell them what to change next time they do the exercise or drill. If it does affect their safety, I will pause the exercise right away and correct immediately.
As for myself from a personal standpoint, I have been very fortunate (and careful) to have a healthy body without any main restrictions or injuries. I have been training hard since I was seven, trained with adults at the age of 12 and did competitive martial arts and bike racing, as well as countless hours of sports in college as a part of my sports education. Anyone who knows me, will tell you I don’t hold back when training either, I give it my all and work my hardest. Through all of this, I have been able to avoid any main injuries that affected me long term (I had a lower back issue at one point but recovered from that). Many and most people I have ever met who trained at my intensity (not clients), have had serious injuries. I believe the main reasons to preventing injuries for myself are:
- I know my body well and know where my limits are.
- Even if I push through my limits, I take calculated risks.
- REST is extremely important, know when to take a break.
- I fuel my body right, nutrition is so vital.
- I take responsible supplements (vitamins, Omegas, and some others such as the following one)
- Glucosamin, Chondroitin and MSM have been very important supplements (comes in one) for me to protect my joints. The difference for me is remarkable.
- I don’t live like a crazy man or do many unhealthy things such as going out, eating or drinking too many bad things.
- I listen to my body.
- Stretch a lot, tight muscles are prone to injuries.
- Personal one: I love massages! They help you recover and stay loose.
- Follow the normal guidelines (warm up well, follow the game rules etc.)
When training clients or groups, I try to share some of these tips with them. It is fully understandable that everyone has their own life and wants to do their own thing. Some things might not even work for someone. However, from my experience, these little and very simple pointers make a huge difference and have kept my joints, ligaments and other parts safe.
Use your common sense and listen to your body. Train HARD but also take care of yourself to prevent injuries!
P.S. Now let’s hope I don’t fall down tomorrow and get injured!

Kettle Bell Certified Instructor at Define Defense
This past Sunday, I got my Kettle Bell instructor certification training by the USAKL. It was one of the things that I’ve been wanting to do for a while and get better at. As a trainer, I was able to do many things with kettle bells but the advanced technical moves were not part of my skill set yet. The reason for this was that when I went to college for Phys Ed, Sports Management and Personal Training, kettle bells weren’t really used in Belgium.
Another reason was that I was shown incorrect form on many occasions. When I went to some other gyms or worked with other trainers, I was shown certain methods to do the clean, jerk and snatch. On all of these occasions, I left with lower back pain and extreme muscle soreness.
At the instructor certification course however, I learned PROPER technique and how to perform the clean & jerk and snatch in a correct way that will increase your skills, endurance, mobility, body awareness etc. I must have done 800 scoop swings yesterday (yes with low weights but still many reps) and there is no sign of any back pain or other muscle soreness.
I was very impressed with the course and am very proud to be a certified kettle bell instructor that can demonstrate correct form in a responsible way. There is of course a long way to go and much to learn but learning these technically advanced moves was a huge step in mastering the idea behind kettle bells, therefore being able to teach safe and performance enhancing kettle bell classes!
Soon, Define Defense will start kettle bell classes, combined with cross training by using all our other cutting edge equipment in our facility. Come check them out and join a class for free. Kettle bell exercises are great to get in shape, strengthen or tone your body and improve your performance. As I experienced, I guarantee you it’s a fantastic workout like you’ve never done before!

MMA for women
MMA is often viewed as a mostly male sport. Even though women have been competing in MMA since the mid 1990’s, there are few organizations which promote female fights and even organize them. As for now, the UFC does not host female fights but Strikeforce does since 2009 (bought up by Zuffa and there are many rumors about Strikeforce going down and UFC taking over the female divisions).
Japan has always been a major spot for female MMA and in the US, names such as Gina Carano and Cyborg Santos have been around for a while. However, from my perspective, female MMA has never been more popular than now and I believe the biggest reason for this is Rhonda Rousey.
Rhonda is in the first place an amazing fighter and athlete. She also handles the media well, does great marketing and is a great MMA spokesperson.
There is absolutely no reason that female MMA should be considered any less than male MMA. I’m positive many of these women would win over many men in the competitive circuit. It’s about time more money goes into this part of Mixed Martial Arts so these athletes can earn more money, therefore live better, train better and get even better as professional fighters!
At Define Defense, we have a nice solid group of great girls/women training MMA. They give some of our guys a hard time and are tough as nails. It is fantastic to see how they enjoy the very tactical and technical sport of MMA and BJJ and stand their ground. We always have everyone work at their level (while pushing their limits) but do not differentiate between male and female MMA clients. Our female members work as hard as anyone else and make our instructors proud!
Don’t ever let yourself get intimidated by the sport. There is no reason to. Try out a MMA class and see for yourself why it’s such a great sport! It’ll increase your self defense skills, get you in great shape and you’ll have a blast doing it!

Student of the Month October 2012

What do poker & MMA have in common?
What do Poker & Mixed Martial Arts have in common? At first, you would think absolutely nothing right?
Well it seems like they have quite a bit in common, both in people and strategies! GSP recently started playing poker (even in the 2012 World Series of Poker), Bruce Buffer has been known for quite a while to play poker and also Mike Swick, Forest Griffin, Randy Couture, Rampage Jackson and Heath Herring (who actually swapped Mixed Martial Arts for the poker circuit) are great Mixed Martial Arts fighters that also have been seen on different occasions in the poker world.
It’s not surprising that poker is often practiced in the Mixed Martial Arts world. Many fighters and fans like the fact that both practices are very strategic and the excitement that one good or bad move can make or break the competition is exciting. This also goes in both ways, people that love poker also enjoy following Mixed Martial Arts. You also have to learn the game and all strategies thoroughly, have many different aspects and require skill and good planning instead of only relying on talent. Both MMA and poker have emerged from the shadows over the last few years and have gained much more respect. It has become obvious that it is not a brainless activity, instead it takes practice, training and discipline.
Now the good news is that you don’t have to go Las Vegas anymore to practice your poker skills. There are good online platforms to do so and the benefit is that you can do it from home and there are no restrictions as to how many people can fit into one casino. If you are interested or want to check out some online poker platforms, check out PartyPoker UK to test your poker skills!

Video: How to stand up from ground position

My Take on Armstrong's Case
As a previous competitive cyclist (nothing like the level of competition discussed but competition nonetheless) and still a huge cycling fan, I feel driven to write this article. Please note, I was never a huge fan of Lance Armstrong and whether I like him or not, that doesn’t change my perspective on the case.
As you know, Armstrong has declined to continue the fight to prove that (he claims) never to have taken doping. The USADA claims he is guilty because he refuses to carry on with this legal fight.
Even though Lance Armstrong has never tested positive during his career, there are also a lot of stories, rumors and the USADA states that they have testimonies of previous team mates of Lance Armstrong, testifying they saw him use illegal performance enhancing products or procedures.
For me, the bottom of the line is: I don’t care! It’s not my place to tell whether he is guilty or not and I don’t know all the facts. When I was racing, I have seen and heard a lot of things and I have my own opinion about Lance Armstrong but that doesn’t matter.
What matters to me is that they are on a witch hunt prosecuting a retired athlete who is not competing at those high levels anymore. I don’t see any organization chasing after our other beloved athletes. What if they took away the medals and trophies of Arnold Schwarzenegger, Eddy Merckx or even Babe Ruth or Michael Jordan? I am not saying they took PED’s for sure but it is very possible some of them did. What is the point of going back in time and ruining people’s lives?
There is a lot of doping in the professional athletic world and I am 100% for testing. I believe there should be no doping because it forces other athletes in doing it and putting their lives in danger. It is also a horrible example for our youth. However, it is there and that is a fact. That being said, if someone passed the tests and they could not detect it, that should be the end of it. Especially when the individual has already retired.
Nowadays, we are able to store blood samples and we do thorough testing. However, there is always a way to cheat the system. Doping is all about new products, cycling, timing and dosage. I have never taken anything and I also didn’t have the ambition to become a professional athlete so why would I?
If this event becomes the norm, different organizations will simply store the blood for years or decades, test the samples then and detect products they couldn’t detect before. Or when a team mate is 70 years old and has financial problems, he or she can sell stories for a lot of money. Is that really what we want to do? Do we really want to go back in time and take away victories and inspiration? My modest opinion says no, even though I am 100% for a clean sport.

Grappling Tournament Sponsorship Opportunities
Grappling Tournament Sponsorships
Many grappling tournaments are based on points which leads to boring matches and people winning by stalling.

This style tournament is the most exciting to watch as well as to compete in.
Define Defense has a significant presence online through our website (over 1,00 views/month) and social media pages (reach of over 9,000 people/week) and will also invite all other studios and training facilities in the Denver and Boulder Metro areas.

Recovery as Indicator
One thing I realized when growing older (and throughout college education, training etc.) is that I needed to pay more attention to my recovery heart rate. After doing a set, an interval, a workout, see how long it takes for your heart rate to drop to (or close to) normal levels. If it continues to race for minutes, you might need to switch up your training routines or in extreme cases, go see a doctor.
If you heart rate drops pretty quickly, then you know your body is able to recover quicker and it is also acting more efficiently compared to someone’s heart rate who stays higher for a much longer time period. It is a great indicator of your current physical condition. If you recover faster, it enables you to do more repetition, keep your intensity high and outwork an opponent. If your body fails to recover, you will be forced to stop or slow down.
The easiest way to check is to count your heart rate during 15 seconds and multiply this number by 4, right after you finished working out or doing your last exercise and again after 1 or 2 minutes. If you continue to do this over a certain time period, you will see if there are any changes. Remember, every individual has a different level, different maximum heart rates, heart rate zones and recovery time. Compare to your own data over time, not others!
Now how do you improve your recovery time? Easy: by training! If are new to training, you will notice a significant difference quickly. If you have been training for a while and don’t notice any difference anymore, you can switch up your training and focus on different ways of working out. You can focus more on endurance (which plays a huge factor in improving recovery times), intervals, tempo training etc. Do things you are not used of doing to keep your body guessing. That is why cross training is so great! It shocks your body and makes it stronger in every single way. This new and improved body will be able to make more progress in the sport you want get better at.
Next time you are working out, don’t only focus on the workout itself, also measure up your heart rate after some sets and after your workout and take notes. These notes will be helpful down the road! It’s not all about training, but also about recovery, rest, nutrition etc.

Father's Day: What to Get?
Sunday is Father's Day! Sometimes it can be tricky to figure out what to get your husband, dad, grandpa, godfather etc. So here are some suggestions of the Define Defense Team:
A TRX Suspension Band: These are some of the best workout tools in the world. It may look like an innocent and easy piece of equipment but it will challenge you, no matter what level you are! Many pro athletes use it and Define Defense uses the TRX Suspension Bands every day for general fitness training, rehabilitation and MMA training! If that's not cool enough, keep in mind it was invented by a Navy Seal!
Brazilian Jiu Jitsu & MMA classes: Get him a membership or a punch card for BJJ or MMA classes! Little boys love wrestling and grappling and deep inside somewhere, all men are still sort of boys. So give him a chance to learn BJJ & MMA. He will thoroughly enjoy it and learn great skills. It is a lot more than just rolling around on the ground, it's a highly tactical and intelligent ground game with many skills and techniques, call it a human chess game if you want. Plus, what do you have to lose? You get a husband that's in great shape and he can protect you better!
Self Defense: Perhaps your husband or dad has been bugging you for years since he's worried about you. Well, you know what the answer is: Take some self defense classes and take away his worries!
Cross Training / TRX classes: None of the above? No problem, get him a punch card or membership for Cross Training / TRX classes and let him pick when he comes to work out. Define Defense has 7 classes every week and no need to register beforehand. He will get a great and safe workout that will give him fantastic results. The instructors at Define Defense are very individually oriented and make sure you reach your personal goals!
Gift card: Can't decide between all these awesome choices? Well then you can just get a gift card and let him decide for himself! He can even use towards our retail products, such as boxing / MMA gloves, rash guards, pepper spray etc.
You can simply come into our studio to purchase or order something or contact us at info@DefineDefense.com
Define Defense at Tough Mudder Colorado 2012

I had a great time since I've been looking forward to it for a long time and was fortunate enough not to have any injuries or limitations. It's great to find new challenges and this particular one would challenge my endurance, balance, coordination, problem solving skills and especially: mental toughness.
Some of the obstacles were especially mentally challenging, such as the ice bath (water with 1.5 feet of ice and you had to dive under a wooden board before exiting), and the electroshocks. There were not one, two but three obstacles with live wires this year! The first we had to crawl in water, second on an ice sheet and the third is the well known one running through live wires. Of course, not all wires are charged but that makes it even more nerve wrecking. I was shocked a total of 7 times. During the last obstacle, right before the finish line, I got shocked twice on the head and it dazed me pretty well. However, I was fortunate enough not to drop (we have seen other people go unconscious for a few seconds). Even though the shocks aren't fun, it's part of the game and it added to the experience. Obviously, if you have medical issues you shouldn't go through the electroshocks.
I did all the obstacles of the course and they were all great for different reasons. A few objections I have with the challenge though are:
- Some of the obstacles that require physical skills, such as climbing, ducking etc. were too short. They should have been longer in length.
- The course was reasonably tough and despite the fact that Tough Mudder needs to accommodate the general population of may different levels, I thought it would be harder. The hardest part of the course was absolutely the altitude changes. You had to run uphill, downhill, hike etc. which was GREAT! That makes it a lot harder but I would like to see harder physically challenging obstacles. Perhaps they should do the course as it is and do some extra things for an 'Elite Tough Mudder'?


P.S. A big thank you to the team and the people who came out to support!

Extreme Diets: Why Do People Do Them?
A few days ago, I was watching a 20/20 episode we recorded a while ago. It discussed a number of diets out there that are controversial, yet a lot of people follow them.
First, the episode showed more about the feeding tube or K-E Diet. This in particular was extremely concerning. Basically, a doctor puts a tube in your stomach through your nose and a pump provides you with a blend of nutrients throughout the day, for a total of 800 calories a day.
This amount of calories is shockingly low as it is not even enough to support your body’s basal metabolism (the amount of energy your body needs to keep vital functions going without any extra activity). Therefore, you end up losing a lot of important tissue in your body which is not fat, plus it is not enough to support your organs to function properly.
Surprisingly, many brides do this diet since it gives quick results for their special day. However, it is not without danger for your health. It also makes your body retain more after the diet and I can imagine many people splurge and gain more weight back later.
The statistics show that 80% of people on diets regain their weight. Now why is that? One reason for it is that most diets are so extreme that people can’t stay on them. They get some results (often not as much as they are hoping for) and they get back in their old habits. Other diets revolve around pills, of which many are nonsense. Some that do have active ingredients may have some effect. However there is no such thing as a magic pill. Instead, you need to change your habits, eat well, work out responsibly and adjust your lifestyle.
Also please be wary of ‘before and after’ pictures. Just check out this video.
We all know obesity rates are extremely high and it is a huge problem. Even though we live longer than we did hundreds of years ago, we can do much better. Many companies and individuals take advantage of people feeling desperate and helpless and promise them amazing results. Unfortunately it doesn’t work that way and even more sad is that so many people believe these ads or claims.
Please do not let someone talk you into spending tremendous amounts of money for something that doesn’t really work or may be hazardous for your health. Instead, find an honest professional who will tell you the truth. And you may not really like it but at least you will do the right thing and get your body healthier. Instead of losing 30 lbs. in 30 days, it may take you 90 days but at least you can rely on this information and your body will become healthier without any exaggerated stress, chemicals or deprivation. Plus you will not have to spend an extraordinary amount of money.
With hard work, dedication and good support, you can change your lifestyle and become a healthier you. However, be cautious and critical when looking for ‘magical’ solutions.

Carb Loading for Athletes
If you are familiar with the term carb loading, you know it’s a method used by a lot of endurance athletes to increase the storage of glycogen (for energy use) in the body.
For many martial artists, this does not necessarily apply if you are cutting weight for tournaments. You can still cut carbs the days before (which you have to anyway) and then maximize your intake after weigh ins but you will by far not have the same exact effect as for example a cyclist doing carb loading because you do not have enough time to load carbs after weigh ins, which are often the day before the event.
An average person in normal circumstances has enough glycogen stored in the body to last you for 90 minutes when doing a physical activity, such as running, cycling, etc.
When you carb load, you can increase the amount of glycogen stored from 25-100% (for adult men shown in some studies, results for women are less steady), which means it your body’s reserves will last you longer than 90 minutes so any loss in performance by lack of energy will be postponed or not be present at all if you fuel your body during the activity.
First and foremost, it is important to increase your carb intake the last few days before your goal event or race. You do need to make sure this does not cause any intestinal problems that may affect your performance. If you have never done carb loading before, try it out before during training to see how your system reacts.
The first phase of carb loading:
A week before the race, decrease your carb intake (don’t cut them out all together) and resume your training as normal. Increase your protein and fat intake to compensate for the lowered carb intake. This will make your body react to the lack of carbs but not deteriorate your body of performance by cutting calories. About 50-55% of your caloric intake should come from carbs during these two to three days.
The second phase of carb loading:
Three to four days before the event or race, increase your carb intake drastically and cut back on your fat intake. At this point, about 70% of your total calorie intake should consist of carbohydrates. Lower your training intensity and frequency to allow your body to store more glycogen (converted from carbs) than normal. The day before the race, rest completely or do an extremely light workout to loosen your muscles.
Even though you do carb loading, you may still feel fatigued during or after the race. This may be muscle damage, buildup from lactic acid etc. Energy storage and processes are only one piece of the puzzle. However when done right, it may benefit your performance drastically. Don’t forget to continue to fuel your body during the race to prevent fatigue. When carb loading, a temporary weight gain is seen frequently. When your body stores more carbs it also stores more water, therefore the weight gain. This should however be temporary. If you have long term weight gain, you are most likely consuming too many calories overall.
Every individual responds differently to carb loading and discuss the process with your doctor, trainer or nutritionist in more depth before attempting.

Bolder Boulder & Tough Mudder
The last few weeks, I have been preparing for the consecutive races I had planned.

Either way, I had a great time and hope to be able to do it many more times. Maybe I should aim to finish under 50 minutes? I have done a 10k before around 45 minutes but that was many years ago and when my body was more designed for endurance sports. That should be a very realistic goal as I didn’t train specifically on running but also on biking, swimming, strength and cross training. Nonetheless, running is a great workout and boosts your cardio. A quality that is important for many athletes. I like to maintain a healthy balance of strength, cardio, speed, flexibility etc. That also means I can’t be a purely competitive endurance athlete but that is also not my goal at this point in time.
I was supposed to do the Sunrise triathlon this coming weekend and Tough Mudder next weekend. However, I will be forced to pass on the triathlon for following reasons:
- I have a wound on my arm that I don’t want to swim with in the Boulder reservoir. It is probably fine but I don’t want to risk any bad infections. I am sure you have heard of the horrible stories that have occurred lately with bad bacteria in lakes (not the reservoir but nonetheless, I’d rather be safe than sorry).
- By having a booth at the Boulder Creek Fest and a big yard project, I haven’t had a chance to recover in weeks. Therefore, I will pass on the triathlon so I can attend the Tough Mudder race. I don’t want to risk pushing my body too much and having to pass on Tough Mudder. We are doing it with a team and I want to participate. Too bad because my training was going fantastic but I don’t want to overtrain.
Unfortunately, the Sunrise Boulder organization was not very helpful in refunding my registration fees because of the wound that may get infected. Apparently they claim they never refund any fees under any circumstances, including medical conditions that may be dangerous to the athletes, whether it’s by own doing or infecting each other. As a business owner myself, I understand you need to reinforce rules but at the same time, also make exceptions. What if someone can infect other athletes, what if I get a heart attack a few days before? They would not refund an athlete? That doesn’t make any sense to me so I believe they should revise their policies as this is not fair or morally correct. I know for sure I won’t be registering with this organization anymore. When someone is unable to train with us because of a valid reason, we modify their membership to accommodate. Simply because it’s the right thing to do.
This week is all about recovery for myself with some cross training sessions to keep my body sharp for Tough Mudder. My cardio is great and I don’t expect an issue with Tough Mudder. And if my body were to let me down for some reason… I tend to be very determined (or stubborn?) in training & races. A quality that people around me don’t always appreciate that much :)

Instructor: Belgium born Sander Vanacker, co-owner and head instructor of Define Defenses, a martial arts and personal training gym, has a passion for fitness. Vanacker has been a martial arts devotee since childhood with extensive training in Wado Ryu Karate and Japanese Ju Jutsu.
Vanacker dabbled in semi-professional cycling in Belgium, triathlons, weight lifting and general fitness training, while getting a bachelor's degree in physical education, personal training and sports management.

Two months ago, Vanacker got TRX suspension band certified. The weight-free exercises allow for more control over workout intensity, he says. He began incorporating TRX into a cross training fitness class.
What is the workout?
The class is a combination of cross training and TRX exercises designed for a full body workout. Utilizing the entire space, Vanaker designs a circuit workout that keeps the entire class energized and alert while working on core, endurance, strength and cardio.
The workout started with running and then made its way through kettle bell lifts, undulation ropes, squats, crunches, TRX suspension bands, and a vibration plate -- just to name few. With music pumping in the background and calls of encouragement or instruction from Vanaker, the class was upbeat and extremely dynamic.
What's different?
The class is a mix of cross training and TRX band exercises enabling a very well-rounded workout. Although the class is challenging, it allows for individual pacing and modification.
"Sander is exceptionally good at being able to modify for injury or specific need," said Aaron Hamilton, a loyal client who has struggled with a shoulder injury for years.
Equipment used:
Vanacker's combination of traditional weights and medicine balls with undulation ropes and a vibration plate is key in keeping the class exciting. I had never used a vibration plate, TRX bands or undulation ropes, but Vanacker was a supportive and knowledgeable teacher who focused on explaining proper technique.
Cost:
The first class is free. Define Defense also has month-based memberships ranging from $85 to $110 for unlimited classes or punch cards, 10 classes for $200 and 20 classes for $350.
Level:
Although this class is not for the weak and weary, you work at your own level. A typical active person could step into the class, never having even seen or heard of circuit training or TRX bands, and be able to keep up.
What to prepare:
Workout clothes you can easily move in are a must, along with some water, although there is a drinking fountain. The class is taken barefoot on the martial arts mats, so workout shoes are unnecessary.
Muscles worked:
It truly is an all-encompassing workout targeting core and oblique muscles, shoulder and arm conditioning, glutes, inner thigh, calf and quad strengthening. It is a highly cardiovascular class that focuses not only on strength improvement but overall health and wellness.
What I loved:
I actually loved the whole class. I have never done anything remotely like cross training or TRX and I was pleasantly surprised. The TRX, though, probably was my favorite, because it's all based on your own strength and bodyweight. Oh and they validate parking, always a plus in downtown Boulder.
What I didn't like:
I didn't care for the shoe-free workout. We were on mats, which was fine, but sweat made my feet slippery and caused difficulty gripping the mat, which caused my balance to be off during some exercises.
How I felt after the class:
Sore, I am not going to sugar coat it. I left the class pumped up on endorphins and loving life, but woke up the next morning with a nice variety of soreness, including my shoulders, arms and upper back, as well as well as my oblique and calf muscles.

Review: TRX Suspension Bands
TRX has become very popular during the last few years. All our clients use it and many other people have used it or at least seen it before. TRX makes Suspension Bands and Rip Trainers (which are also coming to our studio soon).
Define Defense has been using TRX Suspension Bands since its opening weekend. We absolutely love using them for many different reasons. Because they are so great, our head instructor Sander completed the official TRX Suspension Bands certification course.
The background of it is pretty cool as well. The founder was a Navy Seal Team leader and made the Suspension Band when they were on missions and in safe houses. Since there is not much room in these places, they needed a way to stay in shape and work out their bodies. That is how the Suspension Band was created.
Now, years later, it has become one of the best pieces of equipment that I have ever used. My personal biggest reason of this is because you can work so many different muscle groups in ways that are hard to replicate. You utilize your body in such a way that many parts of it are working at the same time, therefore it is extremely functional. Although I do have huge reservations about ‘functional fitness’, the TRX band is the best example of how to do it right. More about my take on functional fitness another time, just realize that TRX bands do work the entire body in every plane of motion. Therefore, TRX training is very practical to strengthen your body for everyday use and activities. It is also perfect to avoid injuries, coordination and body awareness (something that is very important for everyone and especially elderly people).
A great aspect of them for myself is that you can choose any intensity you want. There are many adjustments you can do to change the difficulty and resistance of the exercise. There is no doubt that you can do an extremely hard workout with the TRX Suspension Bands. That is why it’s a perfect workout tool for any athlete because you can train for performance with them. Of course, variation is key and I am a huge believer of using many different pieces of equipment, exercises etcetera but you can absolutely get a very intense workout with simply the TRX Suspension Band.
Many of our clients train for self defense, MMA, Brazilian Jiu Jitsu and more. All of them are able to use the TRX bands very effectively. It strengthens them, makes them react quicker, makes them less prone to injuries, creates better body awareness and core stability etcetera.
Define Defense offers 7 TRX / Cross Training classes every week and utilizes all our equipment during our martial arts classes as well to provide our clients with a great workout as well as learning effective skills for self defense, MMA, BJJ etc.

Great job guys, we’re proud of you!

Training for triathlon & Tough Mudder 04/27/12
Since my last blog post about my training preparations for the triathlon, my schedule has been pretty crazy! However, that is great since that means I’ve been working hard and I’ve had the opportunity to train martial arts or do personal training with many people.
Overall, I have still managed to make progress in my training. I have gone swimming, which actually went much better than expected. I do need to swim more frequently but the initial feeling was good. I swam 1.75km (little more than a mile) with little breaks here and there. I will never be a fast swimmer and it is the weakest part of my triathlon but if I can get through it the same way or a little better than my first (and only so far) triathlon back in 2009, I’ll be happy.
I finished that tri in 2 hours and 34 minutes so you can imagine those 4 minutes have been bugging me. Therefore, one of my goals this year is to do an olympic tri under 2 and a half hours.
My plan is to run the Bolder Boulder on May 28th, do the tri on June 2nd and Tough Mudder on June 10th. The main goal is Tough Mudder so the other races are goals as well but will act more like good training sessions. Between this and the fact that my first tri was at sea level, I have no idea what to expect doing one here. I also gained much more mass since then which means more weight and more water & wind resistance. Nonetheless, I have no doubt I can break 2 and a half hours but it will probably be my next triathlon, which is in September. The Sunrise tri on June 2nd will be more of a practice round to see what my level is at the moment and what needs to be adjusted.
During the last few weeks, these training sessions are the ones that stuck out to me:
- 2 rides back to back: I rode with friends first and afterwards, I rode with my wife. The goal was simply to do more miles and get my body adjusted to the feel of the bike.
- A tempo run at the Boulder Creek Path which hurt but I wanted to see how my legs would feel as I normally run much slower. I do need to do more of these but my schedule has been limiting.
- A 3 hour ride to Lyons and Hygiene with a good amount of climbing for me (try to ride up 205lbs + bike and you’ll understand). We still managed to get an average speed of 17.1miles/hour which was satisfactory at this early point of my training.
- On April 16th, I went running (slow) for about 45 minutes and did a bike ride by myself. Both felt great and the feeling is coming back (thank you muscle memory). Especially the ride was fantastic as it was windy and I had an average of 18.1miles/hour.
- The biggest cardio workout so far: a bike ride to Carter Lake for a total of 3.5 hours at an average speed of 18.5miles/hour. This was a great ride and a very important workout since it will boost my endurance and I didn’t encounter any major problems.
In between these sessions, I did martial arts, cross training, hiking, tennis and some shorter rides/runs. This week has been a bigger challenge as I have not had as much time to do long cardio workouts so I am hoping for this weekend.
My goal for next week will be (in addition to my regular activities):
- A long run
- A shorter fast run
- 2 swimming sessions of 2km each
- A 3 hour bike ride
- A 2 hour faster bike ride
Even though training may not always be easy, find that motivation and satisfaction. That’s what will keep you going!

'If you talk the talk, you've got to walk the walk' - Goals & Determination
When growing up, my parents had a certain saying: It’s better to get a B or C after trying really hard than getting an A without trying at all. That being said, I was a very good student but it showed the values that were important to them. I guess it’s in line with the saying ‘Hard Work Beats Talent’ and I couldn’t agree any more. If things go too easy for you, then you never learn determination, the satisfaction and rewards of hard work.
The point is, you have to work and you have to try hard. If you put a lot of effort and determination in something, good things will come your way. The road may not be always full of sunshine and there will be bumps in the road but nothing ever goes perfectly. This absolutely applies to training as well. If you train hard (and smart but that’s for another article), then you will see progress. If you don’t put 100% in, then don’t expect all your goals to come true.
Now that has absolutely nothing to do with performance. As a trainer, I never expect our clients to perform the same or compare them to each other. For example: I prefer much more that a person is giving a 100% lifting a 20lbs. kettle bell than the person next to him/her lifting a 50lbs. kettle bell without breaking a sweat. Everyone works at their level and gets the equipment suited for them. However, we do expect everyone to do their best and to give a 100% in their workouts, whatever their fitness level allows.

I believe in perseverance or as the saying says: ‘If you talk the talk, you’ve got to walk the walk’ (last saying I promise). Of course, if you don’t enjoy something it is likely that you will quit at some point which is fine! There is so much out there that enables you to choose what you really love to do. Also, you will fail at some goals in your life and that is normal. Everyone does but as long as you gave it a fair shot and put your energy into it, then there is nothing to feel bad about.

My family was always very motivating in every hobby I had but also very strict. I could not be any more appreciative for that. It taught me discipline and determination. At the same time, that is why I was able to reach my personal goals. If they didn’t bother putting rules in place and taking the time to enforce them, I would not have learned the lessons that I did. So find motivation in your training, no matter what it is, be confident and persistent. As your trainer, I will do my part as well as I can but I need to see the focus and determination in your eyes.

Strength & Conditioning for BJJ
The most important thing in BJJ is time spent drilling and sparring. However, if you are planning on competing there are several other factors that matter. Two of the most important factors are strength and conditioning. Are you strong enough to get out of a heavier opponents mount? Do your arms give out when trying to do guillotines? What about your lungs? All of these issues can be addressed when you enroll in a strength and conditioning program.
In combat sports, you are usually matched with an opponent of equal weight and often, as the case with Brazilian Jiujitsu, equal skill or belt rank. Since this is true, it is a good idea to have every advantage over your opponent possible. If your technical ability and size are the same, then the opponent who did more and trained harder will usually win.
The great thing about our strength and conditioning classes is the variety of equipment. For example, when training with TRX bands you can make it as hard or easy as you want. You do this usually by moving closer or farther away from the anchor point. This saves a lot of time usually spent changing weights. Another great thing is the negative resistance training. Negative resistance concentrates on the lowering phase of the exercise. For example, when bench pressing, you would lower the weight very slowly then have assistance pushing it up. This type of training lends itself to great strength gains. It also focuses on stabilization muscles which greatly help your overall strength.
Your overall jujitsu game is by far the most important piece of the puzzle. The more you drill and train, the better you will be. However, if you are matched with an equally skilled and sized opponent, it is usually the stronger more conditioned athlete that wins. Make sure you are doing more than your opponents in all areas of your training. More drills, more rolling, more strength training and more cardio. This is the only way to ensure victory.

Training for summer & Tough Mudder: April 6, 2012
It is April 6th and I have less than 2 months before I do the Sunrise Boulder triathlon and about 2 months before doing Tough Mudder. My training at Define Defense has paid off well and my overall cardio, strength and muscle endurance are satisfactory.
It is time however, to start doing more miles to improve my cardiovascular endurance. I would advise to start of with training many miles and then work up the intensity once the races approach. However, with my work this was hard to accomplish so I trained hard during Cross Training / TRX classes, martial arts and weight lifting until now, which I will keep doing (it is so hard to sit out during classes, I always end up participating in most of them).
On Monday, I decided to wear my heart rate monitor during our Modern Martial Arts class to analyze the intensity of the class. During these classes, everyone works at their own level and will not be compared to one another. I tend to push myself pretty hard and wearing the heart rate monitor was also an extra motivation.

As you can see, my average heart rate was 149bpm and max was 175bpm. That is a pretty high average for me, meaning I pushed myself hard. Please note that everyone’s data would be different and you cannot compare your data to anyone else’s. My absolute maximum heart rate would probably be around 195bpm. This would be accomplished by going all out for a short period of time. During martial arts class, you want to sustain efforts for a longer period of time.
During the warmup, my heart rate elevated pretty quickly. About halfway through, we did some drills and when I was holding the bag for my partner(s), my heart rate dropped. The last part of the class had a higher intensity again and my heart rate stayed pretty much around 170bpm the whole time.
We did push ourselves pretty hard. Some classes will be cardio based and others will be technique based. They are not always this physically challenging and everyone works at their level, working on their strengths and also weaknesses. It does show you, that this class was a great workout and doing this will absolutely improve your cardio, muscular strength, endurance etc.
On Wednesday, I made my first real bike ride of the season. Because I raced back in Belgium, bike riding is a lot of fun for me and has a lot of memories. Therefore, I enjoy doing it and I want to continue to test myself, for example with triathlons.
I did not have an abundance of time so I only rode the bike for a little more than an hour to test my legs. I was pretty happy with the results. My average speed was 18.7mph with an elevation gain of 651 feet and an average heart rate of 145bpm. I held a pace I knew I could keep up but it was still challenging for my legs. I realized my cardio is great but the specific movements to cycling was hard for my leg muscles. This means I simply have to do more miles and train more specific to my goal (triathlon). Specific training to your goal is very important, for any sport. If you do a swimming race, you have to swim and if you do a running race, you need to run. However, cross training does have a very important role in all training.


This weekend, my goal is to ride 2-2.5 hours and in a few weeks, do bike rides of about 4 hours, once or twice a week. I am fortunate to have the experience with the bike and having a good overall foundation to work from. For beginners, I would not recommend increasing the work load like this.
Finally, on Thursday my wife, dog and I went to hike up Mount Sanitas and Dakota Ridge. Hiking is a great workout to work on your training base or foundation. As you can see, the average heart rate was only 122bpm but it is still challenging for the leg muscles when you have elevation differences. It is enjoyable and a good variation in my training. If I was competing with the bike, I would not be hiking too much or consider it a workout in season. But since I am only doing these races recreationally, I do consider this a workout and an aid to my training, especially for the Tough Mudder race on June 10th.

In between these workouts, I of course worked out more. I did some running and cross training, weight lifting and walking. These were simply some interesting notes on my training progress and heart rate data.
Heart rate data is very individual and do not base your performance and especially training program on someone else’s information. If you are interested in building a better training program for yourself, contact us and we can assist you in doing so.

30 Day Paleo Challenge: Final Article
During March, I participated in a 30 day Paleo challenge. As you may have read in my previous posts, my experience was double sided. I did really enjoy some of the healthy changes I had to make, such as eating more fruit, vegetables, soup and nuts. This made a huge difference and got me more into a routine of eating these items, which are of course fantastic for your body and health. Please note I will not go into the details of the diet and what to do, this is purely about my experience and not intended to explain what you should be eating.
Other things, I wasn’t as much a fan of. So many things were cut out of my diet that it caused me to get very bored of certain foods. Also, dropping so much water weight (6lbs. at a certain point) wasn’t very fun. I was thirsty all the time and got dehydrated very quickly, not to mention I looked very deflated (since you retain more water when you eat more carbs).
During the challenge, I ran into a bigger problem though. Since my work requires me to stand, run, exercise and do many more things for long periods of time, my total exercise duration every week (with individual training as well) easily exceeds 15-18 hours of sports. Doing the Paleo diet caused my performance to go down. As I wrote in my previous article, I switched to Paleo for Athletes and reintroduced carbs to accommodate my high levels of exercise. This made a huge difference and got my performance levels back to their original levels (and went up since). This was more in line with how I normally cut weight and watch my food intake when cutting. It is a very manageable way of eating and fueling your body right. The right amount of carbs in the right times are hugely important, combine that with the health benefits of some Paleo ideas and you’re on the right track! Since starting on March 1st, I lost 10lbs, am close to my goal competition weight and did not compromise my performance or lean mass.
In my opinion, athletes need to eat more carbs than the Paleo diet can offer, that is why Dr. Cordain, who wrote the books on the Paleo diet, recommends athletes to make these adjustments.
Even though it was not ideal for me (which I knew beforehand but I considered this an experiment), the Paleo diet may work much better for others. Certain ideas of it make perfect sense and most importantly of all, it does not allow you to eat manipulated and processed foods, chemicals etc. These foods are a huge reason why so many individuals are unhealthy and obese. In my opinion, eating unprocessed foods is one of the most important changes you can make in a diet.
People need guidance. Perhaps that is why the Paleo diet is so popular and I am positive it works for many people. If you are looking to cut weight and you are not very active, it is likely to do just that for you. If you are very active, it may still work but I think there may be better ways. There are many articles and studies out there that tell you why to eat and why not to eat certain foods. Many foods have changed (the nutritional value) over the last 10,000 and even 50 years. However, for every pro study there is a con study. At the end, you need to do what works for you, using common sense.
You should strive to eat as healthy as possible, fuel your body and give it what it needs and don’t get frustrated along the way because if you do, you are likely to give up. Go ahead and cheat a bit every once and a while, just be smart and disciplined about it. If you need help or you plan on starting a new nutrition or training program, go to a professional and ask for advice and motivation, both for nutrition and training needs.

Getting into the right mindset for working out
For training and working out, goals are extremely important. You need to set short and long term goals and make them challenging but possible. If they are not possible, you will not reach them and eventually become disappointed or frustrated. On the other hand, if they are too easy, you may not push yourself enough and not make enough progress, if any at all.
Another aspect of training, one that I feel has played a huge role for myself is having the right mindset. I'm not necessarily talking about what your motivation is for your workouts because there are thousands of reasons why you can, should or want to do it. What I'm thinking about is the attitude, the mindset, the personality you step into the gym with. When you have that mindset, nothing can stop you. You can just keep going and whatever is in front of you, you do not stop. When I go into a workout like that, I feel stronger, faster and better than any other moment. People call me nuts when they see me training (and I probably am) but it gives me great satisfaction and motivation. This is when I get my best workouts and earn some of the nicknames I have been given over the years (Beast, the Hammer,... All for different reasons).
Getting that mindset is not easy and I feel cannot always be planned ahead. It's a feeling of the moment. It may be influenced by your goals, motivation, your previous success and progress or simply how well you slept the night before. It depends on the individual and circumstances but also on the people around you. A good group of training buddies or trainer can get you in that moment, in which you feel invincible and full of energy (sometimes I have to step in to prevent injuries as a trainer when a client gets 'in the moment').
There is nothing like this feeling and sometimes you just start working out and you know you'll be killing it that day. Other times, you need more guidance from a trainer to get in the right mindset. Either way, it should be your goal to find that motivation. It is the perfect intrinsic motivation (because you want to for yourself, not for others or a reward) and when you work out like this, you will feel great after and again be looking forward more to the next workout. It's a vicious circle. If you feel bad for yourself when working out, it will probably not be any better next time. So give it your all. I guarantee that, if you work out hard but responsibly, you will experience that mindset more and more while enjoying every minute of it.
For the beginners out there: no matter what sport you practice, go for it, get over that beginner's hump and you'll find more enjoyment and great progress lying right ahead of you! Leave it all out there and you will experience more results than what you were hoping for!

Switching to Paleo for Athletes!
In my second week of doing the Paleo diet, I found myself to be lacking energy to work out hard and also my performance went down. Especially with weight lifting, the difference was remarkable. Perhaps I didn’t eat enough of certain things or too many of others but whatever caused this, it was a problem. The fact that I teach martial arts and do personal training for a living has surely something to do with it. My body definitely needs more fuel than others since I am on my feet all day and I try to participate when teaching as much as possible. This easily adds up to 18 hours of training every week.
One more problem I had with the diet (which is a personal fault) is that I got bored of most foods. As mentioned before, if you are a picky eater it will become frustrating since you can’t eat certain things and you have to eat tons of others. This is of course a personal problem and most people are not as picky as myself (if in doubt, talk to my mom or wife about my eating pickiness!)
With these issues in mind, I decided to keep the general ideas of the Paleo diet but modifying it so I could again eat more carbs. Therefore, I switched to the Paleo for Athletes diet. This is a customized Paleo diet with the needs of athletes in mind. Our bodies need more energy and need quicker recovery. When training in and outside of classes as much as I do, I believe it is necessary. The first week I seemed to have no issues but after, I felt this was the right thing to do for me personally.
After the first week I dropped 7 lbs. As mentioned before, most of that was water weight, which I didn’t like. Once I started eating carbs again, I retained that water weight back (thankfully because I seemed very deflated!) Once retaining the water put to normal levels, I weighed 210.5 lbs. Since I switched to the Paleo for Athletes method, I dropped to 207 lbs. I feel great and energetic and feel like this is the best way for me to go Paleo. I can sustain my blood sugar levels, am not losing lean mass and am dropping the right weight. I’m looking forward to keep going on the Paleo for Athletes diet and continue to get leaner in my preparation for my triathlon races and Tough Mudder!
Again, this is my personal experience and does not reflect on anyone else and should not be considered nutritional advice.

Cleaning and hygiene in the martial arts studio
Martial arts is a statistically very safe sport to practice, for both youngsters and adults. One of the dangers however, (which you have to be aware of when selecting a martial arts studio for yourself or children) is hygiene. Martial arts mats are vigorously used and are in contact with feet, sweat and the occasional blood (from little cuts on fingers, toes, elbows etc., just like any other sport). That in combination with skin contact can be a hazard.

Martial arts is not any more hazardous than any other sport, think about the equipment you sweat in doing football or soccer; or the materials you are in contact with when doing weight lifting or gymnastics. Simply think about how many people use a regular gym or rec center every day. If you are careful and train at a responsible facility, the risk is minimal!
A few other things we do:
- We offer 2 private showers for our clients to use after their workout
- We sell long sleeve Define Defense rash guards for more protection
- The weight lifting and cardio equipment is disinfected frequently
- We encourage everyone to wear clean and freshly washed gear
In our facility, we have had no issues whatsoever and strive to keep it that way by keeping the studio spotless and disinfected (while using responsible products instead of chemicals)!

30 Day Paleo Challenge: Day 7
Let’s start with the numbers: 7 lbs. in 7 days! I know, I was shocked too. However, keep in mind that a big part of this amount is water weight. Since I eat much less carbs, my body also retains less water. Fortunately, I still feel energetic and have no dips in my energy levels throughout the day. Also, after weight lifting my muscles seem to be recovering at the same pace as they did before the Paleo diet. This seems to demonstrate that my post training recovery is similar and this should prevent muscle atrophy (I hope)! I am keeping a close eye on feeling weak or lacking energy since that may be a concern (although there are no signs at all yet).
As I mentioned before, Saturdays are a pretty intense workout day for me. This is what I did last Saturday:
- Youth martial arts class (teaching and joining in the interactive games)
- 60 minutes of weight lifting (chest and shoulders)
- 30 minutes of a Modern Martial Arts class (Drew taught the rest of the class)
- 30 minutes of a Strength & Conditioning class (instructed the rest without joining)
- 1.5 hour Brazilian Jiu Jitsu, of which about 40 minutes rolling (grappling with your opponents)
As you can imagine, I was eating all day (to a point that my clients said: ‘Are you eating again??’) Nonetheless, I dropped a good amount of weight that day, mostly because I couldn’t keep up with my water intake vs loss.
Sunday and Monday I was mostly out of town, which did not make this diet any easier. Luckily, we were able to bring a lot of previously prepared foods and we had access to an empty fridge where we stayed. This made it more manageable but it was still not easy at all.
So far I have been able to keep up with the diet but it is definitely a challenge. This is not how I normally eat at all. I can imagine the Paleo diet is a slight change for many people but for me it’s pretty much a complete turnaround. The temptation is not a major issue right now, however the biggest problem is variety. This is why we’re exploring more options to cook the same foods, the problem is that I am a picky eater so I am forced to resort to the same foods pretty often. I have to say I am eating many different things but considering the amount of food I have to eat, it gets quite boring.
So far this week these have been my workouts:
Monday:
- 45 minutes weight lifting (chest and shoulders)
- Brazilian Jiu Jitsu class (60 minutes)
- 30 minutes Strength & Conditioning
- Modern Martial Arts (60 minutes)
Tuesday:
- 30 minute run
- 45 minutes weight lifting (back)
- Modern Martial Arts (of which I joined 30 minutes)
Wednesday:
- 60 minutes weight lifting (upper back and shoulders)
- 60 minutes Strength & Conditioning
- 60 minutes Modern Martial Arts
I have not yet measure my body fat % but will most likely do tonight. I will keep you posted!

30 Day Paleo Diet Challenge: Day 2
This is day 2 of my Paleo diet challenge. Please don’t consider me a Paleo specialist, all this is intended for is to share my experience :) Please consult a nutritionist or dietitian for nutritional advice.



Unfortunately, during the first day I couldn’t satisfy my hunger. I don’t think it was as much physical as it was mental. I do believe we are addicted to some foods and after eating those, you need more and more in order to satisfy yourself. Not being able to eat these items, makes it hard to satisfy my hungry feeling! However, since it is such a change in diet, I think it just needs time. The first 2 weeks I expect to be pretty rough. However, today (2nd day) I am doing better already and feel less hungry (believe me, I’m eating a large amount of food).
Training wise I was pleasantly surprised I didn’t feel a dip in energy! I am sure it has a lot to do with all the meals I had, which kept my blood levels more steady. Although, I was still surprised since I did not have any pasta, bread, rice, potatoes etc. and I didn’t feel weak at all. My training yesterday was:
- A light Modern Martial Arts class (60 minutes)
- A Strength & Conditioning class (50 minutes + 10 minutes stretching)
- Teaching a Self Defense class (some parts can be pretty intense when instructors are the subjects to takedowns, self defense techniques etc.)
Today, my wife and I went for an hour hike and I worked out for about 45 minutes (weight lifting) and still did not feel a drop in energy! This was a major concern for me but I’m happy to admit there is no such drop!
Tomorrow I’ll be training a good amount (at least 3 hours) so I’ll let you know what happens!

My Training Progress & Paleo Preparations
Last Thursday, Mike and his wife Jessica told us more about their experiences with the Paleo diet (aka Cavemen diet). The concept of doing the hunter/gatherer diet really appeals to me since it doesn’t allow anything that was not available at that time in history. And if that isn’t enough, just keep in mind that individuals such as Jason Statham, Frank Mir and Forest Griffin use the Paleo diet to cut weight!
I won’t get into the details since I’m not a nutritionist and also don’t know all the details about the diet but here are some great links if you are interested:
During the month of March, I will strictly follow the Paleo diet. It’s my intention to eat healthier (goodbye manipulated or processed foods) and also lean out. After all, many off the illnesses and diseases we deal with are caused by our nutrition.
To prepare, I have slightly adjusted my meal plan already before starting on the Paleo diet. Since last week, I have slightly dropped to 12% body fat. My workouts have been the same but my meals have been leaner. The 2% drop corresponds well with the weight difference on the scale, however I believe I was holding water before which played a factor in my earlier measurements. My body does adjust quickly and is very responsive, which helps a great amount and just makes me more excited for my Paleo experience!
A few examples of my workout days this past week:
Wednesday:
- Bag striking drills and kicks (45 minutes)
- Shoulder workout with cleans, shoulder raises and front raises (40 minutes)
- Full body strength & conditioning class (60 minutes)
- Modern Martial Arts class, leg heavy (60 minutes)
Thursday:
- Drills and games in the Youth martial arts class
- Full body strength & conditioning class (60 minutes, I focussed mostly on abs and back)
- Brazilian Jiu Jitsu class (45 minutes)
This wasn’t my hardest week since I took a few days off and lacked some time to work out. However, the training was plenty to maintain and in combination with my adjusted meal plan, good to cut some weight. My average week will contain 4 weight lifting sessions, 3 full on strength & conditioning workouts and a mix of Modern Martial Arts and Brazilian Jiu Jitsu 5-6 days/week.

Goal Setting: The Next Phase in my Training

The first few years after cycling and doing weight training off and on, I gained a great amount of muscle mass. At this point in time, I weigh about 215lbs with a fat percentage of approx. 14% (up from 8% when cycling). The reason behind the higher fat percentage is less cardio (I was on the bike 18 hours/week) and a less strict diet since I was no longer competing until now.
It was very important for me to retain my full range of motion, flexibility and speed. Mass means nothing if you can't put it to good use after all, especially as a martial artist. This is why I always focussed on explosiveness, speed drills, stretching and giving martial arts training 100%. The right attitude means everything. You can train 6 hours/day but if you only give 50%, results will stay behind. I was also very fortunate to study in a great college (while cycling) and since one of my majors was Physical Education, we had about 12 hours of different sports every week. This absolutely made me a more complete and diverse athlete, challenging me in every way. I feel stronger than ever and haven’t compromised my speed, flexibility etc.

Next week, we are doing a workshop about the Paleo diet. I will do a 30 day Paleo diet challenge throughout March and expect this to be a great help in my training. It will also be a great experience as I really like the idea behind the Paleo diet. I will be posting blog articles, updates and videos about my upcoming training, progress and Paleo diet experience. Every week, I will show you what I am doing and what differences I notice by changing my routines.
Until then, my training will be stepped up a notch and the focus will be on 5-6 meals a day with unsaturated fats, complex carbs and protein in every meal. Drinking lots of water is vital and fruits, vegetables and lean meats will be my refuge. Stay tuned for more updates!

Neuromuscular Electrical Stimulators
If you have ever seen someone using electrical stimulators, you may have thought they were in some kind of medical trouble or so. Fortunately, they’re not (although they are used in rehabilitation to strengthen muscles and prevent atrophy).
Neuromuscular electrical stimulators (NEMS) are used in the athletic world but there is still a lot of potential since many athletes are unaware of the technology. The Soviet Union started using them in the athletic world in the 60’s and claimed their athletes increased their strength by 40%.
Basically, what happens in our body all the time is that the nervous system transports electrical impulses. When it reaches a muscle it makes the muscle contract, therefore move (of course there are a lot more processes going on but this is the most relevant one for this topic).
The electrical stimulator works by the same principle. It send electrical current through the skin and makes the skeletal muscle contract. Depending on the frequency, different types and quantities of the muscle will contract.
At first, the feeling is extremely uncomfortable and this is a turn off for many people. However, you are in full control and can start off easy and build your way up to higher intensities. Different individuals will have different sensitivities so don’t compare levels and intensity of shocks between multiple people.
There’s a few different ways you can use an electrical stimulator as an athlete. The first one is low frequencies, which is great for recovery and ‘massage’. It makes your muscles gently contract to increase blood flow which increases recovery by supplying nutrients and oxygen and takes away metabolic waste products from the muscle. In my opinion, nothing beats sport specific active recovery but using the NEMS is absolutely advantageous, especially compared to passive rest.
The second method to use a muscle electrical stimulation machine (there’s many different names for it but they are all about the same) is to use higher frequencies. This will benefit your maximal strength and power output by targeting your 2a and 2b muscle fibers. The NEMS can make your muscles contract harder than a voluntary contraction (especially with large muscles), therefore recruits more muscle fibers and also offers a more intense training. Treat the sessions as a weight training workout. Do the same amount of sets, duration, rest etc.
The biggest problem of the NEMS is danger of overtraining. Because you are able to recruit more muscle fibers and you are not limited by other factors such as cardio or respiratory limitations, you are in danger of training too hard. This can result in massive muscle damage, too little rest etc. Start of very easy and build up. Many beginners without guidance can’t move the trained area for a few days after their first NEMS workout, which indicates that the intensity was too high.
There are contradictions about this type of training. Some use the argument that you need to train a muscle through the whole range of motion to really shape it and make it stronger. Since NEMS contracts the muscle in an isometric way, only a part of the muscle is being worked at that time (although isometric exercises have a solid place in a workout routine). Pro studies have shown that after using NEMS, many of the benefits are caused by an improved connection between the nerves and the muscle. This enables to muscle to recruit more motor units, which increases power output (therefore more efficient).
In my opinion, NEMS is a fantastic tool to supplement your training! However, sport specific training should always be the focus. You cannot skip training and use an electrical stimulator instead while watching tv and expect the same results. What you should do instead is train hard/smart and supplement your training with the NEMS. Put the focus on training specific, do exercises to maintain your full range of motion and keep shocking your body to make it adapt. A neuromuscular electrical stimulator absolutely has a place in a workout routine but you need to use it wisely.
Stay tuned for some video tutorials on how to use a neuromuscular electrical stimulator (coming this week).
Warning: when used properly, these devices are safe. However, there are many risk factors so check with the seller and your doctor before utilizing the NEMS. Also hire a trained professional to show you how to use the device properly.

About Self Defense Classes & Workshops - Crime, Reports and Bad Decisions
I'm sure you've heard or read about the 20 year old CU student who got ticketed for falsely reporting an attack on University Hill. You can read more about it here.
Her initial story was that she was walking alone when she was grabbed by a 200lbs. knife wielding man. After a struggle, she got away with some minor scratches.
Doesn't add up does it? It may be possible if she was very lucky and the attacker only had the intention to scare her with the knife but did not plan on actually using it. It is definitely possible if she acted and overwhelmed her attacker (you want to take away the attacker's confidence, therefore the Golden Rule of self defense: ACT CRAZY). However, if a 200 lbs. man was wielding with a knife, it would be extremely hard to walk away the way she did. Not just for her but for anyone, including me!
False reports are unfortunate and prevent law enforcement from investigating real crimes. For example:
The armed robbery which turned fatal for Todd Walker (March 2011)
The gunmen who robbed multiple people and sexually assaulted a woman (August, 2011)
A gunman outside the Boulder Community Hospital (April, 2011)
Bank robbery in North Boulder (September, 2011)
CU campus robbery (January, 2012)
Sexual assault attempts (October, 2011)
Does this mean Boulder is an unsafe or bad place to live? Absolutely not! However, as in every big town (and college town), you need to be aware and more importantly, not be naive. Not everyone is trustworthy, you need to be cautious and use common sense.
After all, things happen and you don't control everything or everyone. None of the above victims ever thought this would happen to them but unfortunately it did. We should all try to keep ourselves and others safe. There are many ways to do this but the first step is to realize bad things do happen. Being prepared doesn't hurt. The last thing you want to do is putting yourself in a situation in which bad things can happen.
As a self defense instructor, I spend a lot of attention to all aspects of self defense. It is not simply about the techniques and how to get back to safety but it's also about preventing, scanning, communication (verbal and non verbal), knowing vital points and very important: your mental state.
My wife pointed out an article about self defense a few weeks ago and Linda Fairstein (a former sex crimes prosecutor) addresses a few very bad choices that turned for the worst.
- Kenia Monge from Denver was planning on going to college to become a crime scene investigator so she was an intelligent woman. When she left her friends to go to the restroom when partying, she never came back. Travis Forbes was found guilty for the murder of Kenia. She made one mistake but it cost her and her family dearly. It is very important to use a buddy system when leaving the group, no matter how close or easy your destination is.
- Holly Bobo, a 20 year old student was kidnapped outside her Tennessee home. It seems like Holly did not resist enough, at least not in the initial part of her kidnapping. Traces of resistance were found but it was probably too late. If you feel unsafe, draw attention to yourself. It will lower your attacker's confidence and other people may be able to assist or call 911. Do whatever you can to draw attention and target vital points to maximize damage and pain. Please note that every situation is different and everyone's response is different. When there are weapons involved, it is also a very different scenario so this response may not fit all situations!
- Paula Sladewski had a fight with her boyfriend in a club, it came to a point that her boyfriend was thrown out and she stayed. When she left later, cameras show a man was following her. She didn't make it and up to this day, there is no suspect. Paula made the mistake of making a decision based on her emotions at that time. This affected her safety and it turned for the worst. Always be careful and don't take risks, even if you are upset.
The article focussed on these three situations that were caused by a certain decision. Other people doing the same actions may be fine and many other decisions will also turn out to be the wrong one. Should you lock yourself up and don’t take any risks? No but take calculated risks and please use common sense. It’s better to be safe than sorry. In my mind, every person should take a proper self defense course and know the basics (not because we teach these but I believe things can happen and you should be able to help yourself if needed).
We teach self defense classes 4 times a week and offer punch cards to give our clients the freedom to choose their own times. We focus on every aspect of self defense and make sure you leave with a strong basic knowledge and skill set. All levels and ages are welcome.

Our No Gi Brazilian Jiu Jitsu Program - Downtown Boulder
A little more about Brazilian Jiu Jitsu at our Define Defense studio:
Our No Gi Jiu Jitsu Classes
My main background in martial arts is stand up fighting and self defense (for almost 19 years now). I have also been training Brazilian Jiu Jitsu since 2008. For the first three years, I only practiced with the gi, based on Gracie Jiu Jitsu.
Before opening Define Defense, I met Drew (our BJJ instructor) and he introduced me to the world of no gi Jiu Jitsu. This was a huge change for me since I had never done Brazilian Jiu Jitsu without the gi before.
Drew doesn’t only teach no gi Jiu Jitsu, he also shows great techniques from catch wrestling, Judo and (my favorite): 10th Planet Jiu Jitsu.
This has made my grappling game improve tremendously and now, I feel much more confident and skilled. Of course, we still go over the basics to have a solid foundation but being able to supplement this with techniques from other forms of submission wrestling has made a huge difference. I am now able to catch Twisters, control people with Rubber Guard, catch calf slicers etc. For me, it has made a huge difference, both skill wise and mentally. I can put things together better and am able to think out of the box and make transitions easier.
Gi Jiu Jitsu is still great and I am very thankful I have learned the basics the way I did. However, I feel much more versatile now that I don’t have to rely on the gi anymore (my opinion, I am aware others may have different experiences).
Also, having so many classes each week makes it convenient for everyone else to fit it in their schedule. It’s also a great workout and combining it with strength & conditioning classes simply makes you stronger and more skilled.
More info on the No Gi Brazilian Jiu Jitsu Program here.
Brazilian Jiu Jitsu for Self Defense
For self defense purposes, Jiu Jitsu is the ultimate way to protect yourself on the ground. That being said, there is a certain amount of skills you should possess BUT more would be irrelevant for pure self defense situations.
After all, the chances of your attacker knowing a gift wrap choke is extremely small or doing a banana split would be useless. A great self defense course absolutely needs to teach some Brazilian Jiu Jitsu but it should never be the only thing to rely on. After all, if you can avoid going to the ground, you always should (for example: a sexual assault situation), no matter how good your grappling is. There is the issue of ground and pound, plus your attacker’s accomplice may be just around the corner.
Jiu Jitsu is extremely important for self defense since you do not have to rely on strength; instead, technique will help you get back to safety. Knowing how to avoid situations, accurate striking, stand up self defense locks and techniques etcetera play a very important role as well and a self defense course should offer a complete package of all these aspects.

Training the energy systems
Lactic acid tolerance training
This will improve your tolerance but also your body’s ability to buffer it and increase lactate removal from the muscle.
Intervals of less than 1 minute will require 4-8 repetitions with long recovery periods in between (15-30 minutes)
Longer intervals of 2-3 minutes are desirable but only if you can hold the intensity.
This is a very hard workout so don’t overdo it.
Maximum oxygen consumption training
Intervals of 3-5 minutes, max intensity. Heart rate up to 10 beats under your max.
Improve efficiency of the oxygen transport system.
Anaerobic Threshold Training
Tempo training with speed slightly above comfortable. Intensity should be 60-90% of max and you have to hold it throughout your training. Lactate levels will be above 4 millimol and will build up.
Phosphate system training
Short bursts of maximum intensity up to 10 seconds. Long recovery necessary to prevent lactate production.
Aerobic Threshold Training (Long Slow Distance Training)
More than 1 hour
No lactate production
Comfortable intensity (have to be able to talk)
Will improve endurance and recovery time

Energy Systems
Energy required for muscle contraction is released by by the conversion of ATP into ADP+P
Therefore, ATP sources need to constantly replenished by different energy systems:
Phosphagen System
Readily available in the body and can be used instantaneously for efforts up to 8-10 seconds. Very important for weight lifters, sprinters etc. No lactic acid production and no oxygen necessary.
After the effort, in the first 30 seconds, 70% of the creatinephosphate is replenished and in 3 to 5 minutes, a 100% is replenished.
Lactic Acid System
The lactic acid system provides energy for resynthesizing ATP for events up to 40 seconds (first 10 will be Phosphagen system). It breaks down glycogen stored in the muscle cells and liver and produces lactic acid (no oxygen used which creates an oxygen debt).
Restoring glycogen takes 2 hours for 40% and 24 hours for full restoration after a workout with breaks throughout. For a continuous, high intensity workout, it can take 48 hours.
95% of the lactic acid is removed after 1 hour and 15 minutes so the muscle pains you may feel for the next few days are not lactic acid but micro damage in your muscle.
Aerobic System
Fully activated after 60-80 seconds (warmup is important) to produce energy for resynthesizing ATP from AD+P. Energy sources are fats and glycogen (and protein occasionally).
Primary energy system for endurance athletes.
No lactic acid production or buildup.
However, in most cases, the aerobic system and lactic acid system work at the same time! The ratio depends on the intensity of your efforts.
The best indicator of which energy system you are actually using when exercising is measuring the level of lactic acid in the blood. The threshold (point where both energy systems are working but no build up of lactic acid) is 4 millimoles. Over that and you will get a buildup because your body is producing more than it can take away.
You can raise the threshold by training. An athlete with a good aerobic base (endurance) can work with higher intensity before crossing the threshold.

Supercompensation
Everything we do in our training and our training planning is affected by supercompensation. It refers to the biological state your body is after working out and rest. When you work out, your body is fatigued in many different ways and this reduces the functional capacities of your body. After resting, your body will recover and replenish and if the training stimuli were big enough, you will achieve a higher homeostatic level. This means your body will be stronger, you will have more endurance, more glycogen stored etc.
If you do not allow your body to rest before working out again, you will land in a negative spiral and exhaust your body more. This will lead to decreased performance and overtraining.
If you rest too much, you will lose the supercompensation results and you will be right back at where you started. The right (smart) training and the right amount of rest is key!

Multilateral Physical Development
Different people have different objectives of training. Some may train for a healthier body, others may want to break their own records and become stronger and some want to compete to test themselves with others.
No matter what your objective is, every athlete should work on their multilateral physical development. This serves as a training base and means you increase your endurance, strength, speed, flexibility, coordination etc. Even if it does not directly affect your goal or performance, it is important to work on these things because indirectly they will greatly help you in reaching your goal (and preventing injuries).
For example: a long distance runner still needs to strengthen their core, do speed drills etc. because it will improve their performance. Or a martial artist who runs 10 miles won’t punch harder but will have better cardio and recover faster.
Once you have a base, you need to work on your sport-specific development, which means training to improve in the specific area of your sport.

When and how much to work out?
When is the best time for weight training and how much should you train? It's a question that probably has been asked millions of times. It is a great question though. After all, if you put the time and effort in, you want to make sure that you reap the maximum benefits of it.
The answer is very difficult though. It depends on your physiological state, how much you have been working out, what your goals are etc. it is more important to understand the basics so you are more aware of what you're doing yourself.
I know there are many articles out there about the best time of the day to work out and when you burn the most, have the most energy etc. Fact is, for most people, the best time to work out is when it fits in your schedule! Better to have a great training when you have the time than rushing through a workout when you only have 20 minutes...
As to how often you workout. If you look at professional martial artists and other athletes, they put a lot of hours in the gym but they do split workouts for their strength, then they add cardio and at another time of the day, they will work on techniques. This is not realistic for most people either so a good guideline for someone that wants to add strength and size is to train 3 times/week full body. Work mostly on the large muscle groups and spend less time on the small ones (arms, shoulders). This way, you challenge all muscle groups multiple times a week. Downside is however, you can't spend as much time on each individual muscle group.
Another option is to do split workouts. For example you can do chest and triceps on Monday; legs, shoulders and abs on Wednesday; back and biceps on Friday.
There are many variations and it is up to your trainer to figure out what will work best for you, depending on your goals, level, limitations etc. The thing you want to accomplish is working your muscles hard and frequent enough to stimulate an increase in size and strength without overtraining and making sure it fits in the time you have available.
A few other training splits:
- Four days a week: you will work out half your body one day, the other half the other. After these 2 training days, you will take 2 days off. This way, you get 4 training days per week in and you can spend more time (sets) on the different muscle groups.
- Six day split routine: you will divide your training into 3 different workouts. You train for 3 consecutive days and then take a day off. Then repeat.
- One muscle per day: exactly what is sounds like. Disadvantage is that you can't work out the same muscle more than once a week.
The last question to answer is how long to work out. If your goal is to gain size and lift heavy weights, 30 to 45 minutes is ideal (depending if you work out one or two muscle groups - or more). If you go for high volume training, more sets and more reps for muscle endurance, then a typical workout will be 60 to 90 minutes. If you add cardio for weight loss or to lean out, it can go up to 120 minutes.
Please note that these are only some examples and there are many different options in training. Training planning depends on many different factors and needs to be put together per individual. After all, no two people are the same so the same workout routine will not have the same effects.

Delayed Onset Muscle Soreness
Delayed onset muscle soreness or DOMS is the muscle soreness most people start feeling 12-24 hours after a workout. During your workout, the burn you feel is caused by buildup of lactate, generated by anaerobic energy systems in your body which supply your muscles with energy (ATP).
DOMS however, is not caused by lactate. Instead, it is caused by micro damage in your muscles, especially after weight training, sprints, plyometrics etc. Physiologists used to believe the remaining lactate created the soreness but now we know better.
Even though the muscle soreness is welcomed by many people (it reassures them they had a good workout), it is not an indicator for a good workout. Athletes at higher levels don't get very sore after workouts, even though they trained very hard. It depends on the workout, your physical condition etc. Beginners will experience DOMS frequently until they reach a higher treshold.
If you know your body or your work out frequently, you will know the difference between soreness and an injury. If you feel an injury, immediately have it checked out and act accordingly. If it is soreness, it may last up to 3 days after your workout. If it lasts longer than 3 days or it limits you in normal day to day activities, you probably pushed yourself too hard in that workout.
A frequent question I get is whether you should work out the same muscles when you experience soreness. If the soreness is mild, go ahead and work out but know your limits. You do not have to train until exhaustion or failure every session! You need to shock your body and challenge it so you improve but that does not mean you should push your body to the limit every time.
When the soreness is significant, do not work out those muscle groups. If you do, you may risk overtraining and landing in a catabolic state. At that point, there is no progress to be made, the only thing that can be done is resting so try not to get to that point.
There are a few things you can do to reduce the soreness:
- Stretching when you are warmed up, preferably after your workout. Stretching will improve blood flow and you should stretch anyway to retain your range of movement.
- Cardio will also increase blood flow so there is better transport of nutrients, oxygen, waste etc. A short cardio session with low to medium intensity after your workout is ideal.
- Massages are great for reducing and preventing muscle soreness. It removes waste products from your muscles and increases delivery of nutrients and oxygen.
Even though muscle soreness satisfies us and shows us we trained hard, it is not necessary. You have to train hard but don't worry if you don't have sore muscles after a workout. It just shows your body has gotten stronger. Alternating your workout, using different techniques and switching it up will challenge your body again. Don't do the same workout for 6 months, you will hit a plateau. Make sure you have a lot of variety in your training.
