Lying on the floor, have your legs extended straight up with the ball between your feet. Arms should be straight out to the sides, head resting on the floor.
Inhale and motion ball with your legs towards your left side. When you reach a couple feet off the floor, exhale, and bring legs back up to center.
Continue with the same motion on the right side. This should be one continual motion without any pauses. Return to center for one complete rep.
