Shoulder Extension
Sit on the stability ball with your feet shoulder-width apart and your hands down at your sides. Keeping your back straight, lift your right arm out in front of you, continuing to lift until it's extended straight up, while keeping your shoulder in line with the opposite one, not lifting toward your ear. Slowly lower the arm and repeat with your left arm.

Lying External Rotation
Lie with the ball under one side of your body, with your lower arm resting on the ball for stability. Flex the upper arm 90 degrees at the elbow with your fist pointing in front of you. Holding that angle, rotate the upper arm until your fist points out to your side, then hold for a few seconds. Slowly rotate back and repeat with the other arm.

Swiss Ball Pushup
Lie on your stomach on the Swiss ball, with your pelvis on the top of the ball and your hands on the floor, shoulder-width apart, your legs straight behind you, and your feet pointed up at the ceiling. Push yourself up, straightening your arms until your elbows are just short of locking. Hold for a few seconds, then lower yourself back to the starting point.
Swiss Ball Overhead Press
Sit on a Swiss ball, holding dumbbells in an overhand (palms forward) grip just over your shoulders, in line with your jaw. Slowly raise the dumbbells straight overhead until your elbows are just short of locking. Hold for a few seconds then slowly lower back to the starting position.
