Start in an upright plank position. Bring your left foot to the outside of your right hand, then bring your right foot in and under your hips. Lift your right hand off of the floor. With your weight on your right foot, extend your left leg out to the front. Retract your left foot to meet with the right in a tucked position, weight in the left hand. Now, place all of your weight on your right hand, and extend the right leg in front of you. Sweep the right leg out and around the left leg, placing the foot under the left hip. Put your weight on the right foot and take a large step back with the left leg, while placing your left hand on the floor. Bring the right leg back into an upright plank position.
