Unless you work out at Crunch (which as far as I can tell is a giant adult playground made of oversized foam gears), spending hours at the gym can be incredibly boredom-inducing. Not for this guy, who turned a vanilla elliptical sesh into serious realness.
Unfortunately, we can't hear the invisible symphony that is inspiring him to move so angelically. Any guesses? The obvious choice here is Lady Gaga, but I can also see early 90's Madonna.
Probably definitely not Bon Iver.
