Cobra on Swiss Ball

1. Lie your chest over a stability ball, keeping your legs straight and your arms touching the floor in front of you.
2. Extend your arm back in front of you to the starting position and repeat with your other arm.
3. Without bending your elbow bring one arm out to the side of your body - up to shoulder level - squeezing your shoulder blade.
4. Slowly lower both your arm to the ground and chest back to the stability ball, returning to the starting position, and repeat with the other arm.
