Prisons have universal sets and even some prisons have a weight training class with free weights... I think tht ur talking about just being in like a county jail.. Why wouuld you do jail workouts when there is a perfecally good gym for u to workout at??? Just asking.. Because tht kind of jail training really dosnt hit the mark if you ask me because u never know the true weight tht ur pushing and with workouts like tht there is a whoe bunch of room for injury because of the off balance it has in the weight.,,. My advice would be to stay in the gym.. You gain a whole lot more tht way my friend...
