I use this simple exercise myself & with my clients as part of a routine to maintain healthy shoulder function. Why? - because its involves internal rotation, external rotation, thoracic extension  (great for our posture) & fires up the triceps! Yep we don't just do sports massage here at MassageHull.com, we're here to get you moving well & keep you moving well.
