3 Exercises for Shoulder Impingement (That Actually Help)

Shoulder impingement - pain at the top or front of the shoulder during arm elevation - is one of the most common presentations we see. The term has fallen out of favour clinically because pinching isn't really what's happening, but the experience is real and the treatment is well established.

Why the shoulder hurts

The space between the top of the humerus and the acromion (the bony roof of the shoulder) narrows during arm elevation. When the rotator cuff is weak or the scapula isn't rotating properly, the head of the humerus migrates upward and the tendons get compressed. The fix is restoring normal movement mechanics, not just resting the shoulder.

Exercise 1: Side-lying external rotation

Lie on your non-painful side with the affected arm on top, elbow bent to 90 degrees. Keeping the elbow pinned to the side, rotate the forearm upward toward the ceiling. Pause at the top, then slowly lower. This directly targets the infraspinatus and teres minor - the most commonly weak rotator cuff muscles in impingement. 3 sets of 15 reps with a light dumbbell.

Exercise 2: Scapular wall slides

Stand with your back flat against a wall, arms raised to 90/90 (goalpost position). Slowly slide the arms upward toward full elevation, maintaining contact with the wall throughout. This trains the serratus anterior and lower trapezius - the muscles responsible for upward scapular rotation that creates space in the subacromial region. 3 sets of 10, slow and controlled.

Exercise 3: Thoracic extension over a foam roller

Place a foam roller perpendicular to your spine at mid-back level. With hands behind the head, extend gently over the roller, working segment by segment from the mid to upper thoracic spine. Restricted thoracic extension is a very common finding in people with shoulder impingement - the shoulder compensates by overusing the acromioclavicular joint. Even five minutes of this daily can produce noticeable improvement.
