Begin in a prone position lying over a stability ball. The feet should be shoulder width apart with the chest/sternum resting on the ball. Instruct the client to perform a chin tuck (cervical retraction). The arms will initially be positioned along the sides of the body with the palms down to perform shoulder extension, or the “I” movement.

“I” - slowly extend the arms lifting them up. Pause at the top and then return to the start position. Perform 10-15 repetitions.

“T” - the arms are now perpendicular to the body and resting on the ball. Palms may face down or the shoulders can be externally rotated with the thumbs pointing up. Slowly lift the arms up squeezing the shoulder blades together. Pause at the top and then return to the start position. Perform 10-15 repetitions.

“Y” - the arms are now elevated to about 135 degrees of shoulder elevation. Again, the palms may face down or the shoulders can be externally rotated with the thumbs up. Slowly lift the arms up squeezing the shoulder blades together. Pause at the top and then return to the start position. Perform 10-15 repetitions.
