paul the man to listen to is paul egg, hes been doing it a while
also changine routine DOES help alot, ive been trying to get my back bigger for a while, ive joined a new gym thats just big weights and sterod gorillas in there ( hope non of you use it read this ) and my back is fucking killing me, but its growth pain rather than joint pain as ive been having that for a whlile too since i twisted my shoulder with a dumbell ( always get someone to squat you at all times when pushing big weights)
