Put both feet up against a wall with your toes on the ground and get into the push-up position. Next, walk your hands in towards your feet, bringing yourself up into the “pike” position. Bend one leg and pick your foot up off the floor. This leg will stay in this position throughout the entire movement. On the other leg, bend at the knee and lower to approximately two inches off the floor, then squeeze the quads and straighten the leg. All the movement should come from the knee only. Repeat as many as you can up to 30 and then switch legs.
