LOL. Yeah, when I read "Rampage juiced" my first thought was, why didn't he use a steroid for endurance then? Hahaha. Good cardio WILL take you a long way. But at the top levels, athleticism makes a huge difference. It's a different game now. I mean, look at BJ Penn. Prodigy. Black belt in 2 years. Great fighter. Great technique. He just can't keep up with the athleticism of these guys anymore.
