depending on ur workout ie if u spent most of ur time sittin around talkin and fookin about or if u work ur ass off and have next 2 no breaks.

if u work out for anymore then 40mins solid per session ur doin to much. and thats from some of the biggist fookers at the gym. but if u wonna go mad and b like mr olympia then u'll need to workout like 6 days aweek at least 2hrs a day (broken up of course)
