When your buddy gets in there he’ll find out how the other inmates workout, and use whats available. I’ve done my share of time in a few different places, and they all have different set-ups for working out. Dips, chins, pushups, and squats ( inmate on your back) are the same every where, but also different types of ropes made from sheets ( braided ) that allow for all sorts of variety on rows, shrugs, flys. We had a 4ft block wall, where I’d stand on one side, and my buddy would stand on the other side, I had a 6ft long rope with a hoop in each end, I’d pass it under his arms, and hold each end while he let himself fall back staying planked. Then I’d row him, with my chest up against the wall. Awesome exercise, I wish I could duplicate in the gym.
Also watter bags, in most jails the juice comes in clear plastic bags, so you drink them and fill them with watter, then fill pillow cases with these water bags, with handles on top. One place I was at, had water bags from 20lb up to 70lbs, they were a little big and akward, but they worked. Things get found and thrown out once and awhile by the guards, then the imates remake them, and get smarter each time, making things better, nothing but time to figure things out.
The point is, that your buddy will figure all this out when he gets there, getting in with the workout crowd is a good way to do your time, it fills your days, and keeps you safe. most jails lock you in your cell for lunch nowdays, so I would do my abs and cardio in the morning, then have a nap at lunch, while locked down. After lunch we would workout to kill time till dinner, lockdown. On a range of 32 guys, there’s usually 5-8 guys that workout serious everyday, and this becomes your group, other guys are running around trying to get dope or tobabaco, and other contraband. This causes fights and problems, but the guys working out usually don’t get sucked into this nonsense, and when somthing does happen, they will stand as a group, because of this, the workout guys get left alone.
Tell your friend, if he hasn’t gone in yet, and hasn’t done time before, just to sit quietly for a day or two, and see who’s working out. Find the right time to ask if he can workout with them, if he has workout knowlage, it’ll help. Most of the inmates I’ve seen, don’t know much about weights, and nutrition, and since I’m a trainer on the outside, I get treated like a hero, just don’t come off like a know it all, or step on the toes of the guy already designing programs
If he can quietly get himself in with this crowd, his time will go well. It’s not like the movies, it’s just a bunch of guys playing cards, and working out, just mind your buisness on everything else. Goodluck !
