Bodyweight Exercise from Mike Mahler

Stolen from a Mike Mahler bodyweight article (his main page here). Description:

"Go into a full squat and then do a half roll back. Touch your feet to the floor behind your head and quickly reverse the motion. Roll forward into the bottom position of a squat. From there jump into the top position of a pushup. Do a pushup and then return back to the bottom position of the squat. Stand up and repeat. Save this exercise for the end of your workouts on the road as a finisher. "

Looks like a decent alternative (if non-plyometric) to the burpee; more of a squat emphasis. It'll at least get you a few odd looks at the park.
