Look at the age range of cons, then you’ll see why gym facilities are not a luxury in jail, they are a necessity.
Cons are usually between ages 16 through to around 35, the main recreational physical activity age group.
Many cons come to jail heroin thin, fact is that were it not for jail, then a large number of them would be dead - just a question of how many others they take out with them.
Many cons overcompensate for their dangerously unhealthy lifestyles, and make the gym the centre of their world.
Active recreation is an outlet for stress and agression, if you work in a large enough company then you may have stress management counsellers, who will inform you that active recreation is one of the best therapies for controlling stress.
Jail is an extremely stressful environment, and remember that the more stressed out the cons are, the more duress the staff will undergo, it is their working environment and prisons management have a duty of care for their employees just as much as to the cons.
I cannot think of a prison in the UK that does not have organised work, it is seen as essential to the security of the establishment.
Mandatory training sounds all great and wonderful, but you are thinking in a non-con mode.
Cons usually will not do anything unless they can see a direct personal benefit, such as parole, movement to easier jails etc, and the result is that they may volunteer themselves for education and training, but they are only going through the motions.
Rare is the con that actually does want to learn, this would be seen as compromising himself to the prison authority by other inmates, not a very safe option.
You cannot force any person to learn using legal methods.
As for tough manual labour, its been tried for centuries, hasn’t worked in terms of rehabilitation although society itself might benefit from the work performed, however why should the prison system use cheap labour to unfairly compete with workers who have committed no crime and need a job ?
One thing that folk must remember, that the overwhelming majority of offenders will be relaeased into society, locking them up in isolation, or brutalising them is not a terribly good idea, you’d just get more psychopaths on the loose.
The fitness gained from using the gym is lost very quickly, any athlete can tell you that, not many cons on release have the abiltiy to structure their lives to maintain their physical fitness, given a few months they are pretty much like everyone else, maybe worse if they’re back on the drugs again.
Inmates do not get to work out all the time, they have to work, they have to complete courses ranging from anger management, to psychiatric evaluation, education, drug counselling, courses to improve reasoning etc.
Ture they do not pay for recreational facilities, if you want to take part just commit a crime, trust me, it’s price you would not want to pay, just for a few hours a week free gym time.
