Trying to gain some muscle mass cause i'm pretty darn skinny. I add push-ups to my routine sometimes. For a while I was doing 200 push-ups a night in sets of 25-30. After doin weights I usaully do sets of push-ups like wide, close, reg. and chair push-ups. By doing this is it gonna stop me from gaining mass?
Oh! and I run a mile or more a night except Sundays and do pull-ups too..
But I eat ALOT!
