Supraspinatus stretches help you to prevent injury and increase movement in this small but significant muscle. The supraspinatus is located in your rotator cuff and aids in rotating your arms. Using a side deltoid stretch is the key to stretching this muscle, which maintains your shoulder flexibility and range of motion.

One Stretch to Rule Them All
To stretch your supraspinatus, use the side deltoid stretch. According to Exercise Prescription, you can do this stretch with or without support from a bar. To do it without a bar, place one arm across your chest and the other hand on your elbow. Push your elbow toward your chest and hold for 20 to 30 seconds, then repeat for the opposite side. To do a side deltoid stretch with a bar, in what is called the fixed-bar side deltoid stretch, hold a stationary bar at chest height and turn your chest toward your arm. Hold the stretch for 20 to 30 seconds, then repeat for the opposite side.
