Upper limb movement for further stabilization of the posterior aspect of the shoulder.

In order to engage the rear deltoid muscle more sufficiently, the arms should be elevated to almost 90°. The arms stay internally rotated to further foster rear delt activity.

Pull the cable as close to your face as possible while maintaining proper posture and a good connection with the ground. Try to keep scapular movement at a minimum.

Often the posterior structures of our shoulder joint are poorly developed. Especially in overhead movements we lack shoulder stability. I personally found it useful to then seek the overhead position in some form or another and move it under load.
