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