One of our favorite exercises for chronic shoulder pain is isometric shoulder strengthening. An isometric exercise involves using the muscle without moving the joint through a range of motion. This is a great initial start to a strengthening program to bring stability to a joint.
Isometric exercises can be done in all directions to strengthen multiple muscle groups. This easy exercise can be performed by positioning yourself near something that can provide resistance, like a wall. Then gently push your arm into the wall and hold for a few seconds. Sounds straightforward enough, but this is also an easy exercise to compensate with different movement patterns. The pattern we most often see people doing is performing a shoulder exercise using their trunk rather than actually using their shoulder (as demonstrated in the above photos, be like picture 2 not picture 1!) Trunk stability in this exercise is essential for proper shoulder strengthening.
