Muelio im not claiming i no everthing about body building but i no that no one on here is 100% right everyone has there own way of doing things, if you go to the gym and afterwards are feeling sore and tired the chances are that you have done a good days work. your muscles can hold a maximum stress load so the only way to make them bigger, stronger is to push them. in a way you want to be breaking the muscle so that when you rest it in grows back bigger and stronger ... belive me alot of the people on here talk shit soo i would do what you doing if i where you just make sure your upping you weights very couple of weeks and that you working everything you what to be working cheers conor.
