If you don’t have a barbell, use a broomstick or a pipe of some sort.

Excellent rehab/prehab for the shoulder. Strengthening the internal shoulder reduces your chance of shoulder injury. Good stress is applied to the infraspinatus, a rotator cuff muscle.

Grab the barbell as if you’re trying to mimic scarecrow arms.

Bring the elbows up to shoulder height (while keeping shoulders depressed).

Rotate up overhead while keeping the elbows bent at 90 degrees.

At tempo, bring it down to shoulder height again, not all the way down.
