It's bizarre, a punch in the face hurts less when you win than when you lose.
I’m a martial artist, and I don’t train because I have a fight; I train because it’s my lifestyle, and I’ll train every day if I’m not hurt.
I had two ACL injuries in my life, and both of them happened when I was training with bigger guys; a heavyweight and a light heavyweight. Sometimes it's not even because the guy is good, you just get hurt.
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.
