Start in the proper position for a standard push-up.
Drop down towards the ground like you would for a standard push-up.
When you reach the bottom of your range of motion, use your arms to push yourself in an explosive motion as high into the air as you can.
While in the air, reach down and touch your toes while keeping your legs straight. (Complete a pike in while in the air.)
Land as softly as you can on your hands and toes back in the push-up position.
