Moving the elbow out

Do not lift your upper arm sideways and turn external rotation into arm abduction.

Bending the wrist backward

Do not move your hand through wrist motion instead of shoulder rotation.

Choosing excessive tension

Do not use a band that makes you swing beyond the control of the small rotator cuff muscles.

Pulling the shoulder back

Do not forcefully squeeze your shoulder blade back to imitate forearm rotation.

Returning inward too quickly

Do not let the band pull your hand into your abdomen.
