While facing a wall, place your hands on the ground two to four feet away from it. Then, using a bit of momentum, kick your left leg up over your head until it reaches the wall (A). Do the same with your right leg. Immediately bring your left leg off of the wall, and lower it to the ground (B). Then bring your right leg off the wall, and lower it to the ground so that you’re in the starting position. That’s one rep.
