Hello All. Been back in the gym for about 5 months now and have made nice gains. Im up about 20lbs, natural of course. The difference is like night and day on a 160lb frame. My shoulders really need help. Its no surprise as they are my least favorite body part to train. Looking for some excercises that will give them some outer definition and that overall canonball look. How many sets should I be training them? Thanks for the help.
