Thought this was a little interesting. I think its kind of weird that everyone keeps making a big deal out of his green belt in kyokuskin karate. If he's been training for 20+ yrs in karate, which is what the article implies, it seems pretty reasonable to expect him to be a black belt. Seems like his martial arts credentials are pretty thin.
Probably more important is that he's walking around at 300+lbs right now with little bodyfat and the other guy is about 70lbs less than that. The size and strength difference is immense.
