@qurban I’m pretty sure it’s just for shoulder rehab. I don’t think it’s working any muscles, but instead stretching tendons/ligaments that you are about to work.
I guess there could be other uses for the movement though.
@qurban Bilateral External Rotation ?
I do this as rehab for my torn rotator cuff in my shoulder. I think there are options without bands, and instead you use a light dumbbell or other weight.
Is this what you’re seeing?
