Swiss Ball
Body Parts

Step-by-step instructions

1. Place the ball against a wall and lie back on it so your upper back is supported and your butt is in front of the ball hovering above the floor.
2. Place the soles of your feet together and rest them on the floor in front of you.
3. Brace your abs, push your knees out, and drive your feet into the floor to raise your hips until they’re level with your torso.
