LOL ya that's pretty crazy the most i've done was 30 rep squats and i was on the gym floor heaving after that, he must have some set of lungs on him. Can you just IMAGINE the burn in your legs from 100reps, lol. And ya i would have to say that i think that wouldn't do much for muscle growth i'm all for high rep squats but 100 reps I think is overkill. As Lee Haney once said "stimulate not annihilate".
