Well, it's likely been said already, but I've seen men who are clearly going to the gym to "fix" themselves, as you put it. While there are of course those that are there to perfect themselves (oddly, these are the guys that seems to spend more time hanging around the free weights talking than they do exercising).
At least at my gym, I notice that the majority of females I see at the gym don't appear to be in need of much fixing (ya know what ah mean (say that one in your best EMH voice

). Best ask them yourself though, I'm no expert.
Personally, I'm mainly there to keep fit, get a bit of tone and hopefully ward off the dreaded paunch while I'm at it! :O
