Begin in a standing position Squat and place your hands on the floor Kick your feet back while simultaneously keeping your arms extended so that you are in a plank position Perform a push-up Drive both of your knees back underneath you into a squat position Lift your hands off the ground, stand up, and jump with your arms above your head Land and repeat for the prescribed number of of repetitions. Despite the relative simplicity of this movement, it packs a punch in its ability to spike the heart rate and quite literally bring you to your knees. A case can be made, however, that this exercise may not be the best use of one's time and is, in fact, quite overrated. Breaking the movement down into smaller, more simple exercises could prove more effective.
