Introplay - A great site to track your workouts and keep motivated

A friend of mine just launched Introplay, a site where you can track all of your exercise workouts and also keep your motivation level high. It's a Web 2.0 site where you compete with friends or other members of the site in workout competitions, or leagues as they are called. Even if you didn't want to participate in the leagues, the site has a great workout tracker so you can monitor your progress.

Check out the blog or visit the site for more info.
