my long, lost brother magoo is right. we all respond to the same stimulus. my system may not be as efficent as magoo's or vice versa but, the solution is never to up volume. i will say that if an individual hates training in hit or low volume fashion but, loves high volume then that is whgat they must do. training must first be looked froward to. to dread ones workouts is the first step to failure. personally, i dread the fact of spending hours on end in the gym since i work in one anyway. when a person does not respond to low volume it is usually obvious why when you watch them train. growth is not hard to come by. it is slow but, should not be stagnant. like magoo said, cause trauma (in other words cause a adaptive response) let muscle recup (in other words sound nutrition and rest) then hit it again. i truly believe anymore in the more frequent one can hit a bodypart the better one will respond to training. many will disagree but, ....the thing i tell my members is that if u can not train a muscle at least two times a week then you must a) reduce the amount of volume or b) reduce the in intensity so that you can hit that muscle more frequent. it is simple. when i was following a type of hit program i found that all i could do was two sets a bodypart if i went to failure. any more than that and i could not hit that bodypart again that week. yes, just one more set made it impossible for me t train that bodypart twice in a week. some might be able to get away with more but, not me. the thing that is universal in all is to stimulate growth as often as possible. when one comes to that conclusion then they will find high volume next to impossible. AND NO, ROIDS DO NOT GIVE YOU AN EXCUSE TO UP VOLUME. take advantage of their workings but, do not switch gears. you will only be disappointed.
