well for one thing, that looks to me like around 15% body fat. I don't think a woman can survive with 3% - and from the picture she's not cut like a bodybuilder. Not that it's not impressive!

It's true that swimmers and divers tend to have a lot more subQ fat than other athletes. I'm not sure why - I hope someone here can enlighten us because I've wondered about that too!

But also, that's a publicity shot. I don't really follow swimming, but obviously they don't compete in bikinis, so I don't know if I've ever seen a picture of a female swimmer's abs before. I wonder if she really is built any differently from her peers. From what you can see of her thighs, they aren't cut at all, and her arms, not much.
