I have been doing 1. shoulders and legs 2. chest and tris 3. bi and back then one day off and then repeat. I feel like im not gaining as much as id like so i am gonna switch from 12 10 8 6 to 10 8 6 and more weight and one body part a day. Im also startin a ph sus500. Question is does this sound like a good mass and strength work out?? or should I try something else??
