Up your core workout with the addition of stability ball planks, demonstrated below by Rick DiScipio, Assistant Manager of Fitness.
- Get into plank position, placing your forearms on top of the stability ball while your feet are planted on the floor.
- Lift your chest up so that your weight is supported by your forearms.
- Squeeze your glutes and tighten your abdominals.
- Start by holding the plank position for as long as you can. To add an extra challenge, move the ball in small circles, making sure to go in both directions.
