The sleeper stretch targets which part of the shoulder?

The sleeper stretch is specifically designed to target the posterior capsule of the shoulder. When performing this stretch, the individual lies on their side with the shoulder to be stretched down. The arm is positioned out in front of the body and is gently pushed down towards the ground. This motion effectively stretches and mobilizes the structures at the back of the shoulder, particularly the posterior glenohumeral capsule, which can become tight and contribute to shoulder stiffness or limited range of motion.

The posterior capsule is critical for optimal shoulder function, especially in athletes and individuals who engage in overhead activities. Tightness in this area can lead to shoulder impingement and other related injuries, making the sleeper stretch a useful exercise for improving flexibility and overall shoulder health. This exercise is widely recommended in rehabilitation settings and by sports medicine professionals to address limitations in posterior shoulder mobility.
