Great topic. As for competing, hell no.
On one hand, if I were going, I'd definitely want to have the weights there. I would see it as a priviledge for sure. A huge problem is that there are some people in there that DO NOT need to be lifting.
It seems to kinda float along the punishment v. rehabilitation argument.
Some good "For" reasons -
Self defense - Based on image, you may not get fucked with as much. No one wants to mess with a bigger guy. Survival could depend on it. An assumption, based on my lack of experience.
Endorphin release - keep them happier. Happier means less problems. Another assumption (see above).
Keeping them active - activity builds upon itself. Someone who is busy is likely to stay busy. Plus they have a goal and a focus, no matter how mundane (we all want to make X amount of money, improve ourselves, get the hot girl, etc.. They could focus on the getting to the weight, strength and shape they want).
Against:
They do have access to pretty much anything. Juice would be pretty easy to obtain. You have the same guy who wants to survive from above against the sociopath who is looking at the immediate, wants to gain any advantage, and has no regard for other people. He gets out and is a bigger, stronger, more aggressive, testosterone filled sociopath. Could be a far larger problem to society.
Many view prison as a punishment and this extends into that realm. Why should they be given this chance to better themselves? They did fuck up (not saying I agree, just the argument for argument's sake.)
The violence in prisons is high enough. Why let them do something in which their test gets raised higher (naturally or unnaturally), making them (possibly) more aggressive?
All in all, I'm kinda on the fence about all of this. I can see both pros and cons.
A few things are certain - there are some criminals who do not deserve access to lifting. It should be decided solely on the individual, their behavior before the crime and upon entering. Having the lifting rights taken away can be a good thing.
Conversely, as for punishment, I think exercise could be used as a great way to do this for the younger, more capable prisoners.
When I was in military school (back in the old days, not now), I was punished for getting into it with an officer when I was a new cadet. My punishment? That fucker took me out every night for a week and forced me to do wind sprints until I puked, and then I did some more. I collapsed in my bed afterwards, dreading the next night. I got in shape, but the price was pretty steep.
Trying this with prisoners may not be such a bad idea.
The Good: They'll think twice before getting run into the ground, especially if they are in a labor camp.
They'll get in shape, just like they want to. Focus on their cardio, rather than their testosterone.
They would have to deal with possible consequences of being knocked out asleep.
Humility factor - the guy is getting run into the ground like some high schooler after football practice.
The Bad:
Injuries can and will happen.
Can't be used for everyone because mitigating factors (age, previous injuries, etc.)
Having to deal with being out cold asleep from exhaustion (see above, also a bad - leave the guy defenseless)
That's just an idea. Anyone on here who has spent time could probable tell me whether or not this is a good or bad idea. My .02.
