When you go to the gym you see all these super buff dudes doing all sorts of crazy routines that involve dumbells, barbells, kettlebells, BOSUs, handles, straps, and, of course, that torturer of abdominal muscles everywhere, the workout ball. How do they get so good on these apparatuses? They beat off on them, off course? This stud works on his balance while doing what looks like masturbatory crunches on his ball. Good thing he does it in his bedroom, because we have a feeling this would cause a bit of a scene (or a feeding frenzy!) if he did it at the gym.
