Sit on the stability ball with your knees bent and your feet flat on the floor. Hold the dumbbells in front of you with your arms bent at 90-degree angles and your elbows at your sides. Keeping your back straight, bend slightly from the hips.
Straighten your arms and extend the weights behind your back, turning your palms toward the ceiling once your arms are fully extended. Pause, then return to the starting position.
