Being the workout nut that I am, I think that is is not only sexy visually when a woman is in good shape, but it is sexy emotionally to know that a woman puts that much time and effort into her nody. I think most men and women appreciate a woman who takes care of herself. Having said that, "different strokes for different folks". For every 1 person who is attracted to that look there is 1 that is not. I agree that too much muscle looks unnatural on a woman (or man) and takes away from the femininity.

But that is just my opinion and preferences...
