This blog post is… well about myself. I am not writing this because I love talking about myself or out of narcissistic tendencies. I am posting this because I have had many questions about my background in martial arts, fitness, education etc. This is a great visual way to show everyone what I’ve done since I was a child that relates to my profession now.
I have been involved with a lot of different sports (especially in college of which I don’t have any visual materials for) and always continue to learn and try new things.

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
About Self Defense Classes & Workshops - Crime, Reports and Bad Decisions
01/02/12 15:20 Filed in: Other | Self Defense
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.
