Iv always been off the same thinking, but have tried different methods and got mixed results. Started training my back loads a while back and it got huge quickly then for a while I started doing stuff all over 3 or more times a week almost randomly...with rowing machine sprints in between. I struggled to put on size but I got fit as f**k and looked real good too, had people asking what I was taking to get in such good shape and I was completely clean not even any supps or shakes.
My goal isn't to put on size by squatting daily, but my quads will definitly grow I'm going for definition whi
