Why does it work better?
Wouldn't it be the same if you went to failure with the same rest time? Your weights would probably be a tiny bit lower since you'd be more fatigued from the extra few reps, but it seems virtually the same.
not with 45 sec rest periods, and alot of sets. (which gives you more loading in the end) also eventho volume is higher , you spare cns ...(you will feel fresh instead tired and uninspired)...can workout more often and in a more positive state of mind.
haney was on to something with his "stimulate dont annihilate" (altho i dont agree with everything he did..but i agree about that)
