For me there is no reason why to go up in weight class, because when you go up in weight class you have to fight bigger guys - then you have to train against bigger guys. The guys are not better, they're heavier, but it means you have more chance to get hurt.

I don't want to be an exception, because I was very outspoken about Performance Enhancing Drugs. It would be bad for my reputation if I would have an exemption [for doping test] - I don't want to have a free pass, I want to be like everybody else.

It's not about how you are when things go well, what defines you is how you are when you fail from an obstacle.

The key to effective visualization is to create the most detailed, clear and vivid a picture to focus on as possible. The more vivid the visualization, the more likely, and quickly, you are to begin attracting the things that help you achieve what you want to get done.

There is a difference between a fighter and a martial artist. A fighter is training for a purpose: He has a fight. I’m a martial artist. I don’t train for a fight. I train for myself. I’m training all the time. My goal is perfection. But I will never reach perfection.

Sometimes I'm under the impression some of the fights happen that they shouldn't happen because a guy's cheating. Also, I think when something like this happen they should have not only a suspension but also monetary wise enforce a penalty. Maybe take the purse of the fighter to the other fighter.

Kyokoshin I've done most, but I competed in Sports Karate also, that's my style that I come from, and mixed with the wrestling that's how I got the takedowns.
