lol No. Its funny to listin to all the shit heads talking about how big they will get in jail when serving for long periods of time. Unless you can steal the whole blocks worth of trays there is no way you could get in enought protien to get any mass. Its all starch. And you eat 3 small portions a day. The water you drink comes outta a toliet/fountain so that sucks. And its hard to do good workouts without weight. Some small guys can get pretty lean because they dont have anything in them and will do mad amounts of sit ups and other little cardio. You do have all day. I will just exercise all day just so I can sleep at night on the shitty plastic mats they give you. Other then that.....Its a walk in the park
