human growth hormone - somatropin - - I agree with Alcatraz re: Oly lifts and explosive power. One needs explosive power and endurance for MMA more than just being big and strong ( though that never hurts). I have to admit that I gas before smaller, weaker oppenents in training because they have better conditioning. I'm 48 so I don't do more than train and spar now. In a match, round 3 is a bitch if you don't have the endurance to explode when an opening presents itself. My sensei emphasizes kettle bell work, plyometrics, and high rep counts with things like 1 1/2" steel rod doing sword exercises to strenghten forarms and hands, pinch grip carrys, throw and roll with heavy bag, heavy drags, and just repeated forms and rolls etc in his conditioning class. He does all this as one long class with very little rest time. It's very tough. I wish I could make it to class more often.
