I'm curious about the 5x5 routine. I've never really had a strict workout plan, I kinda just do whatever I feel like hasn't been destroyed enough and it works pretty well. I never liked doing the same stuff every week for a couple months it gets too boring. But the 5x5 seems cool. My question is whether its geared towards size gains or what?? I'm a pretty small build and have to work hard to gain even a pound after weeks. Would this routine be something that might be good for me or just stick to heavy weight and low rep routines.
