Sit on the stability ball holding the dumbbell with both hands. Slowly begin walking your feet forward as you tuck your tail under, lowering your spine onto the ball as you walk your feet away from the ball until your head, shoulders and upper back are resting on the ball. Feet should be parallel and shoulder width apart. Knees are bent to about 90 degrees with your thighs and torso at or nearly parallel to the floor. Distribute your weight evenly through your feet. Finally, lift the dumbbell straight up over your chest as the palms rest on the underside of one of the sides of the dumbbell.

Inhale and slowly lower the weight down in an arc behind your head, while keeping your arms straight, stretching out your chest.

Exhale as you return the dumbbell back to the starting position.
