So most of you here are cutting like mad to get those 'abz' for the summer. Me, I'm only 140lbs at 5'10" at 10% bodyfat, i've been told I'm built but only from skinny people. Anyway, I've started lifting 2 years ago but it's been on and off. I've started seriously lifting for the past month and went up to 147(i know its not much but it's still some gains) and I recently got sick and went back down to 140. This summer is my senior year and I really want to make a change, I'm not expecting to come back to school huge and ripped, but how much mass can I gain if I am extremely dedicated over the summer break (2 1/2 months).
