External Rotator Cuff Work with Gymnastics

I don't believe this has been addressed before. Any ideas on on working the external rotator cuffs using rings?

Thanks!

Body rows, front lever progressions and pullups.

I am sure you can hold with your body sideways, elbow in your ribs and rotate your shoulder. Play around with it.

You can do great work with elastic bands or circling your arms with real small free weights (verry cearlfully and do not exaggerate).
