Anchor a band to the base of a bench or rack behind your head, lie back and hold the band with the upper arms vertical and elbows bent so the hands sit above the head.
Keep the upper arms still and the elbows in.
Extend the elbows to straighten the arms over the shoulders.
Pause at the top as the band is stretched hardest.
Bend the elbows slowly to return.
Breathing: Exhale as you extend, inhale as you return.
