Stand with all your weight in your right foot, abs engaged and chest lifted.
Reach your torso forward as you lift your left leg behind you. Reach your arms out to the sides for balance as your torso and leg come parallel to the floor.
Hold this position for a moment, and reach through your left heel to engage the back of your left leg.
Moving in one piece, lower your right leg toward the floor as you return to standing upright, resting your left foot lightly on the ground. This completes one rep.
