Supine Windshield Wipers

Instructions

1. Lie on your back and raise both legs to vertical (or to a 90-degree bend at the hip), arms extended out to the sides for support.
2. Keeping your legs together, slowly lower them to one side without letting your opposite shoulder rise.
3. Return your legs to center, then lower to the other side.
4. Continue alternating sides in a controlled windshield-wiper motion.
5. Keep your core tight and move only as far as you can control.
