There is a lot of conflict out there as to how many times you should train a body part per week. Some say you should train each body part twice a week e.g chest monday and friday while others say that can leed to overtraining that you should only train body parts once a week.
currently i train body parts once e.g chest and tri on mondays. back and biceps on wed, shoulders and deltoids on fri and legs on saturday some times i add extra small chest work out on fri with my shoulder work out.
I have tried training twice a week program for each muscle group but didnt notice any gains.
But i never get big any way.
What do others find the best and do you notice much difference?
