Movement:
Begin in a push up position, with your weight supported by your hands and toes. Flexing the knee and hip, bring one leg forward until the knee is approximately under the hip, or if flexible and strong enough, just under the chest.
Explosively reverse the positions of your legs, extending the bent leg until the leg is straight and supported by the toe, and bringing the other foot up with the hip and knee flexed. Repeat in an alternating fashion for “X” amount of seconds or reps
