That's exactly who it looks like! But with less massive arms. Or the pecs at least. Someone at bioware definitely had a pecs fetish. Yeah, most swimmers have a very soft look to them, especially the women. Something to do with being in the water I think. And I didn't mean marathon runners obviously. Muscular atheletes- Sprinters, throwers, boxers, ball sports. One kind of "athlete" actually does have that bodyshape- olympic lifters. But that's you know, lifting things.
Hmm, maybe I'm remembering it wrong. It's been a long time since I played the games. I just seem to distinctly remember that Hawke seemed more slender and less buff than your usual video game protagonist. I just googled it and yes, you're right, he has massive pectorals xD
The thing about the word "athletic". It's just an adjective. The definition I was aiming for was more along these lines: having a sturdy build or well proportioned body structure (from dictionary.com). Nothing to do with athletes proper. I agree it's very vague, so I clarified "athletic but nothing over the top". As I said, the first example that comes to mind of the body type I'm referring to for a man is Andrew Garfield.
For a woman, I was thinking something more like female Hawke. You can clearly see she has well defined muscles and has an athletic build without her having to look like a "rugby player".
