Good post and Holyfield working with Haney is another alarm bell signalling his clear PED abuse. No doubt about it he was a machine of a man but the amount of lean muscle he put on was incredible. Regarding tendon strength and working with light weights, I read a fascinating article which made sense, it was a workout plan that emphasised partial reps and other techniques, once you mastered them all you then added weight. It was much slower than your typical progressive overload routine, routines that are just not realistic once the weight starts adding up.
