Icon Inspiration

I want an exercise/fitness icon, and I'd prefer a manga one, but I'm having little luck remembering anything that would work, especially if I want to use a female character. I tried one of the frames of Revy (Black Lagoon) doing her crazy reverse pullups belowdecks from vol. 7, but it isn't coming out very well - too much of the scene was hidden by speech balloons to really get an idea of what she's doing once it's cropped in tightly.

Anyone have any ideas?

I can always do something with a photo from Flickr Creative Commons, but that's not what I really want.
