ABC of Fitness, great learning site.

A little hokey but the site is filled with a lot of good Flash videos. ABC-of-Fitness.com claims to be a complete fitness, exercise and health portal. From my poking around it is great at showing you correct movements and positions, along with pointing out muscle groups being work. The fitness area has always been a little tacky but still when you have individuals doing the basic exercises wrong, sites like this have real meaning.
