exercise ball dip

Sit on the stability ball with your feet flat on the ground and your knees bent at a 90-degree angle. Place your hands on the ball beside your hips, fingers pointing forward. Engage your triceps and push through your hands to lift your body off the ball, straightening your arms. Lower your body back down by bending your elbows, keeping them close to your sides. Repeat for the desired number of repetitions.
