Check this guy out!  He does WAY more than just work out on a treadmill at the gym. 

Watch the guy work out AND dance at the same time on the treadmill.  A stranger video taped the man after watching his moves every day.  I gotta give it up to him.  I can barely walk on a treadmill without falling.  And I know I can't dance like that on a non-moving platform!  He's in the zone and getting a way better workout than the guy next to him who's just doing his boring workout.
