sure there might be some flaws in his HIT training as we all have observed but i think he was trying to revolutionize the way we would train like he said"more is better when it comes to economics, the more money the better". but this does not apply for weighttraining, more is always better. what im trying to say is that if its recommended to do 15-20 for a particular muscle why not 40-50 sets if more is better.MM TRAINING, I BELIEVE IS A NEW APPROACH TO THE WAY WE CAN TRAIN, BUT IN ORDER TO FULLY EXPLAIN OR UNDERSTAND HIS THEORY OF TRAINING WE MUST UNDERSTAND WERE HE MIGHT OF GONE WRONG. i GUESS IMMA LOOK INTO HIS THEORY.IMM GOING TO PUT HIT INTO PLAY AND SEE HOW IT TURNS OUT.
