Half Burpee

To do Half Burpees, set up in the high plank position with your hands under your shoulders and your feet about shoulder-width apart. Then jump both feet up and outside your hands so your in a squat position. Try to really jump all the way outside your hands. 

Quickly jump back into plank. Try not to let your butt go way up in the air as you jump from the squat back to plank and from the plank into a squat. Move quickly jumping into the squat position and back out into plank. Do not let your hips sag or your butt go up in the air in the plank position.
