3 hard working sets per exercise is enough. whats your goal? just wondering because 3 mins is a long wait between sets..

My goal isn't really specific. Just to get big and strong LOL.

Seriously though, my goal is to bulk and I really don't care about definition (I realize diet is a big part of this).
