Anyone doing weight training of any type NEEDS to be strengthening their rotator cuff, or they're toast (they are going to get rotator cuff tears, impingements, labrum tears, other shoulder injuries, etc.). But very few know how to adequately strengthen their rotator cuff muscles!!

The two most important rotator cuff muscles to focus on are the Teres Minor and the Infraspinatus.

Both muscles externally rotate the shoulder, but there's one all-important difference between them:

The Infraspinatus is engaged during external rotation with your elbow tucked into your side (aka shoulder adducted)... but the Teres Minor is ONLY significantly engaged during external rotation when your elbow is raised 90 degrees to the side (aka shoulder abducted). So you NEED to equally work BOTH positions, and along a variety of angles, for a healthy, strong rotator cuff!!
