Place your elbows directly under your shoulders, distributing your weight evenly over each. Straighten your body by raising your knees off the floor.

Slightly shift your weight to the left elbow as you fully straighten your right arm, so that your hand is placed where your elbow was.

Repeat by shifting your weight toward the right arm, allowing the left elbow to be lifted and fully extended.

Reverse this process and return to the start position. Do not let your hips drop or uper body sag into your shoulders.
