Indeed such women are rare and are probably sick of men who are after them, however, I'm also the kind of man that women hunt after in a similar manner.
What about just visiting any place that attracts single women (wearing tanktops or dresses, hopefully) such as bars, for example?
If even a mega city like New York doesn't offer the diversity of girls to satisfy a certain taste then I'm glad I don't miss anything not living in such a metropolis. :DAnyway, my experience is the same as Chainers... athletic girls (next door types) aren't that rare. Btw - more muscular athletes are usually surrounded by their own kind. I'm pretty sure they expect similar athleticism of their vis-a-vis when it comes to dating. So better hit the gym :D
Seems to me it's never a good time to hit on girls. They always hit me back!
The Internet? 90% of the hot chicks, with muscles or without, are fake. :P Unless you're paying for their webcam ...You'll find plenty of female athletes in college but many of them bat for the other team.
