Forget Zumba, yoga, hot yoga, hip hop yoga, or whatever other kind of yoga there is. The latest fitness trend has nothign to do with breaking a sweat, or busting a move or doing anything more then walking around. It's called Prancercise, and it looks like an easy way to get your cardio in. 

We can't tell if this is a joke or not. If it is a joke, well done. If not, uh, what was that?
