whilst I don't completely disagree with that point, he would shoot for long periods of time. In Arnies new encyclopedia of bodybuilding he talks about time for regular people, mentions when he went to the gym in the morning there were a few dedicated people also their at 4am (attorneys and such), also when he was first bodybuilding professionally there was only a couple people making a living from the sport.
so whilst he would have time, he would also make time
one of my mates, skinny bloke, got on roids for a brief period of time, said he has never been so hungry in his life
