Plank With Ball
- Place your palms against the top of the stability ball. Extend your legs and balance on the balls of your feet. (Note: the closer together you place your feet, the harder your balancing challenge will be).
- Firm you abs and flatten your lower back. Stretch forward through the crown of your head and back through your heels.
- Hold this position for 30 seconds. As your core becomes stronger, work your way up to a minute.
