How to pick your personal or group fitness trainer
As a trainer, I’m very critical towards other trainers and expect the same from them. Everyone can always continue to learn and should take steps towards continuing their education and skills, no matter how long they have been a trainer.
Now how do you choose a trainer? I’d like to share some things I find important to ensure that you select the right trainer who can help you reach your goals. First, you have to figure out what you’re looking for in a trainer:
- Is there a certain style, workout program you want to pursue or a specific piece of equipment you want to focus on and is the trainer competent in teaching it?
- Are you looking for someone to give you tough love or to hold your hand?
- How much time and money do you want to spend on a trainer and does his/her availability and price fit into your plan? Many people can afford a trainer on a regular basis if the trainer proves to offer a big return in experience, knowledge and results!
- Important: are you ready for this?
- …
Next, once you know what you’re looking for, it’s time to learn more about your trainer:
- Does he/she have certifications and if so, are they valid and significant? Personal trainer certification companies just pop up every other day. Many require some reading and an online open book test. This doesn’t make a trainer. Intense classes, exams, hands on training and a whole lot of time makes a good trainer (and even so, there are some incredibly smart trainers out there who still don’t get results because of other factors).
- Is he/she in shape? I know this is discriminating but would you hire a dermatologist with bad skin or a child psychologist with badly behaved kids? I doubt it. It’s the same with trainers. If they take their job seriously and love what they do, they’ll do it for themselves. I know of many trainers and coaches (both fitness and martial arts) who have all these goals and years later, haven’t accomplished any of them. Not a good sign.
- Does the trainer have people skills? He/she doesn’t need to be the most social person in the world but they need to be able to push you, motivate you and help you when you need it.
- Are they experienced in many different workout methods, equipment and programs? Variation is huge in fitness training, both for your physical results and to prevent mental fatigue. The trainer needs to be able to switch things up and keep it fun by adding variety.
- Is the trainer open minded and critical at the same time? Being open minded is an important thing in training (and everything else). New equipment or methods may come out and it’s great to take advantage of that. A good trainer will take great things from different sources and put them together for a superior training experience. At the same time, being critical is vital because there are a lot of useless things in the fitness world. It is a multi billion dollar industry so many people out there promise you everything but give nothing but false statements.
- Does the trainer do any kind of assessments? These are great to check on your progress but also keep you motivated.
- Does the trainer offer packages, multi clients sessions etc. These might save you some money!
- As with some chiropractors (from my experience), a trainer who pushes you to buy their supplements, is a huge red flag. It’s ok if they introduce you to it or if you ask about it. However, if they keep being forceful about it, find someone else!

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!

This program combines all of the most effective and realistic ways to defend yourself against any dangers that may occur. We focus on prevention as well as protecting yourself and others. In this course, you will learn how to deal with a crisis situation, mentally as well as physically. Everything we teach is relevant to real situations and applies more realistic training methods for improved results.

Tentative Schedule for Fall 2012
Here is our tentative schedule for the fall of 2012. As you see, all programs have a great selection of classes and class times.
If you have any recommendations or comments, go on our forum and leave them there. We will be compiling and reviewing them and make any changes that are possible to accommodate your requests.

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.

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.

Define Defense is proud to announce that Conor “Hurricane” Heun is our new Mixed Martial Arts & Brazilian Jiu Jitsu instructor. Conor is teaching the following Friday nights and will be teaching 2-4 times every week starting the end of February. The other MMA classes will be taught by instructor Sander Vanacker. NOTE: All MMA & BJJ classes will be 1.5 hour long!
Conor is a highly skilled and experienced professional MMA fighter who fought under the Strikeforce banner and who also has a brown belt in 10th Planet Jiu Jitsu under Eddie Bravo. He is known for his will power and mental strength as well as his work ethic and technique.
Our 1.5 hour classes will be a blend of MMA and MMA specific Brazilian Jiu Jitsu. As for now, Conor is teaching MMA skills step by step, therefore since a fight starts standing, we cover the standing skills first. In March, we will go over grappling from the bottom, followed by dominant top position etc.
Come train at Define Defense with our instructors Conor Heun and Sander Vanacker now! This month, we give FREE strength & conditioning classes along with our MMA memberships (12mo: $125, 6mo: $140, 3mo: $160), which gives you unlimited access to our 15 classes/week in TRX, Kettle Bell and Warrior Training.

Unsatisfied and unwilling to give up on his goal of becoming champion, Conor enrolled at Div. III wrestling powerhouse, Ithaca College. Following a redshirt year on the sidelines, Heun notched 20 wins and qualified for the NCAA tournament. He failed to place. Faced with injuries and rising academic pressure, Heun would never again see the NCAA tournament.

After graduating with a BA in English Literature, Conor moved back to Boulder where he opened a silk screening business and became an assistant wrestling coach. Feeling like he was destined for bigger things, Conor moved to southern California where he took a job selling dental equipment. Looking for a way to stay fit, Conor began training at Eddie Bravo's 10th Planet Jiu Jitsu Academy. Encouraged by training partners Jason Chambers and Amir Rahnavardi, Conor stepped into the cage for the first time on May 12, 2006 winning his pro debut by rear naked choke.
Conor soon began training full time under the tutelage of Chris Reilly and Eddie Bravo at Legends MMA. His exciting and aggressive style soon caught the eye of Bas Rutten who recruited Conor to fight for the Los Angeles Anacondas in the International Fight League. After fighting in the IFL for one season, he moved on to fight for Elite XC and now is under contract with Strikeforce. Always one to bring the fight to his opponents, his never boring style continues to make him a star to watch as he battles for the belt.
