I don't know what the beef is with work out rooms, it is good for anyone to burn up energy. Without the weight piles they just work out in their cells.
What you don't understand is the resiliency of the human being. The tighter you lock down a man, the stronger he comes back. You can't break someone by taking things away. He will survive, it is part of our biology. You are silly to believe that making prison horible is in any way a good thing. People thrive when put under pressure, and they come back 10x as bad. Believe it or not, this is true. Ping-pong, weight piles and tv do not make prison enjoyable. Get over it.
