I just have a couple of issues;
Firstly the selective colour. Personally I don’t like it at all, but that’s subjective and besides the point, but here it seems very random and unconsidered. For example, in one image a lone weight in the b/g is red, in another her shoelaces. If it’s going to be used it should be used to emphasis the most important part of the image that you wish to draw our attention to. Her shoelace isn’t important, unless it’s an advert for shoelaces :). I got the impression you were asked to do selective colour as red seems to be part of the gyms branding? If they wanted that then that’s another issue, but still I would say be more careful with what is colour selected.
Another issue, is not with your images but with your ‘about me’, which, and I’m not trying to be mean, but sounds like a lonely hearts advert more than a professional profile.
