Common Injuries to the Rotator Cuff Muscles (Subscapularis):

Here's a great video from our partners at The (P)ReHab Guys reviewing some shoulder stability rehab exercises. Listen to what they have to say about shoulder strengthening, “QUESTION: “Why is it important to keep a stable scapula?” . Think of it like this. If you were required to walk on a bunch of bosu balls to get to the opposite side of the room, wouldn't you think it would require more overall demand in comparison to walking on a firm or stable surface? Same idea applies with the shoulder. The Shoulder (Gleno-humeral) moves off of the Scapula. The scapula is a free floating bone, when this isn't stabilized your shoulder must work extra hard. #StabilizeProximally . What is the first joint that you loaded as a baby? Your Shoulders! It has been a while and it’s time to get back to loading those shoulders! A closed chain exercise is a great way to really feel the scapular stabilizers activate.” The Pre Hab Guys.
