I wouldn't dispute that technology has improved the likelihood of getting it right. At the same time, I think it would be naive to place too much trust in technology.
In fact, there's a worrying aspect to it. Jurors are largely, in my view, poorly equipped to judge the quality of scientific evidence. This may sound arrogant, but I don't think the standard of scientific literacy is very high. Jurors tend to be uncritical about prosecution evidence that sounds sciencey, in the same way they are uncritical about eye-witness testimony (which we now know is often less reliable than it might appear).
THIS ^^^ is the more important issue, not what they do behind bars, it's making sure the right people are behind bars.
My literal, unexaggerated solution would be for inmates to provide public services, so in regards to the original post, no they shouldn't be allowed to work out in gyms. But only because, like Trevor said, inmates shouldn't have the energy by days end to lift weights. Again, though, they're amenities are secondary, IMO.
