i find lots of the moves work a lot of my body parts so it makes sense, however; i just cant believe that doing 15 reps of a bench press 1 or twice a week is enough for my chest. I've seen a shrinkage in my peck muscles since I have started and after my one set of chest excersizes I dont feel like I did anything. What other ss technique uses the chest? I'll be adding a dumbell press to my routine I think. Anyone else find this?
