here in a recent interview with FHM leonardo dicaprio claims to have gained 30 lbs of muscle....
FHM: You were scrappping all the way through "gangs of new york". how did you prepare for it physically?
Leo: i put on 30 lbs of muscle and i was working out like crazy
FHM: Do you enjoy "lifting"?
Leo: No, i dont. its my least favourite thing on the planet i spent six months working out five times a week and then it got postponed for another seven months. So i had to continue working out. I hate going to the gym. I hate pushing weights, it doesnt do anything for me
