bodygain.com?

Hey dude, I just stumbled on a site that might be useful for us. It's a whole website optimized for tracking your workouts, with automated charts and calendars and all this other stuff. I'm wondering if we should switch from this blogspot to create profiles on bodygain so we can use all their features. Here's a sample profile in their charts section:
