This is my monday routine, it usually takes atleast an hour and a half, and im dead after it, but i dont see any way around 29 sets. Monday is bi's/back, tuesday is chest, thursday is legs, and friday is shoulders/tri's...am i over training with this many sets? One thing that concerns me is that the only muscle that is sore the next day is my lower back from deads. am i doing something wrong?
