Shoulder Impingement Exercises

What Is Shoulder Impingement?

Shoulder impingement happens when the tendons of your rotator cuff get pinched between two bones every time you raise your arm. Picture a rope sliding through a narrow tunnel. When that tunnel shrinks, the rope starts fraying.

The “tunnel” is called the subacromial space, a gap between the top of your arm bone (humerus) and a bony shelf on your shoulder blade (acromion). Normally, this space measures about 1 to 1.5 centimeters. That’s roughly the width of your pinky finger. When poor posture, muscle weakness, or repetitive overhead movements cause this gap to narrow, the tendons and a fluid-filled sac called the bursa get compressed (Michener et al., 2003, JOSPT).

This compression triggers inflammation, pain, and that classic “pinch” when you lift your arm to shoulder height or above. It accounts for 44 to 65 percent of all shoulder pain complaints, making it the most common shoulder problem physical therapists treat.

The good news? Exercise therapy works as well as surgery for most people at the one-year mark (Kuhn, 2009, JAAOS). That means you can likely fix this yourself with the right program.

Exercises That Fix Shoulder Impingement

The key to beating impingement is a phased approach. You wouldn’t run a marathon the week after spraining your ankle. The same logic applies here. Start gentle, build strength, then return to full activity.

Research shows that scapular-focused exercise programs significantly improve both pain and function in subacromial impingement (Haik et al., 2016, BJSM). The APTA recommends exercise-based rehab as the first-line treatment, and that’s exactly what this program delivers.

Phase 1: Pain Relief and Mobility (Weeks 1 to 3)

The goal here is simple: calm things down and restore basic range of motion. Do these daily.

Pendulum Swings Lean forward with your good hand on a table. Let your affected arm hang straight down. Swing it gently in small circles, about 1 foot in diameter. Do 10 circles in each direction, 2 to 3 times per day.

Passive Shoulder Flexion (Lying Down) Lie on your back. Use your good arm or a broomstick to push your affected arm up toward the ceiling, then overhead. Do 10 reps for 2 sets. This moves the joint without forcing your injured muscles to do the work.

Cross-Body Stretch Pull your affected arm across your chest with your opposite hand. Hold for 30 seconds, repeat 4 times. You should feel a stretch in the back of your shoulder, not sharp pain.

Doorway Pec Stretch Stand in a doorway with your forearm flat on the frame at shoulder height. Lean forward gently until you feel a stretch across your chest. Hold 30 seconds, do 3 reps each side.

Scapular Squeezes Squeeze your shoulder blades together like you’re trying to hold a pencil between them. Hold 5 seconds. Do 15 reps for 3 sets. This wakes up the muscles that keep your shoulder blade positioned correctly.

Phase 2: Strengthening (Weeks 3 to 8)

Once your pain has decreased and your range of motion is improving, it’s time to build strength. Do these 3 to 4 times per week.

Sidelying External Rotation Lie on your unaffected side with your elbow bent at 90 degrees. Hold a light dumbbell (2 to 5 pounds) and slowly rotate your forearm upward toward the ceiling. 3 sets of 10 reps.

Band Pull-Aparts Hold a resistance band at shoulder width in front of you. Pull it apart by squeezing your shoulder blades together. 3 sets of 15 reps. This strengthens the muscles between your shoulder blades.

Prone Y’s and T’s Lie face down on a bench or the edge of your bed. Raise your arms into a Y position (thumbs up), then a T position. 3 sets of 10 each. These target the lower trapezius and serratus anterior, two muscles that are almost always weak in people with impingement.

Wall Slides Stand with your back and forearms flat against a wall. Slide your arms up and down while keeping them pressed into the wall. 3 sets of 10. If you can’t keep contact, move your feet further from the wall.

Phase 3: Return to Function (Weeks 8 to 12+)

Serratus Punch Get into a push-up position (or a plank on your knees). At the top of each rep, push your upper back toward the ceiling, spreading your shoulder blades apart. 3 sets of 10.

Shoulder CARS (Controlled Articular Rotations) Stand tall and slowly make the biggest circle you can with your arm, keeping tension throughout the entire range. 5 circles each direction. This builds control at every angle.

Exercises to Avoid

While you’re recovering, stay away from these movements. They narrow the subacromial space and make impingement worse:

You can return to these exercises once you’re pain-free and have rebuilt adequate rotator cuff and scapular strength.

Treatment Options

Home Exercises

The program above is your foundation. Pair it with ice or heat therapy for pain management. Ice works best for acute flare-ups. Heat is better before stretching.

Physical Therapy

A PT can assess whether your impingement is caused by poor scapular mechanics, rotator cuff weakness, postural issues, or a combination. They’ll customize your program and use hands-on techniques to mobilize the joint. Most people see significant improvement within 6 to 12 weeks of supervised PT (APTA Clinical Practice Guidelines). If you’ve never been to a PT before, here’s what to expect at your first visit.

Medical Intervention

If 3 to 6 months of consistent exercise hasn’t helped, your doctor may recommend a cortisone injection to reduce inflammation or, rarely, arthroscopic surgery to create more room in the subacromial space. But remember: exercise therapy produces outcomes comparable to surgery at one year for most patients (Kuhn, 2009, JAAOS).

Warning Signs

If any of these apply, see a doctor before continuing your exercise program.

Recovery Timeline

Phase	Timeframe	What You Should Be Able to Do
Pain relief	Weeks 1-3	Reduced resting pain, basic arm movements comfortable
Strengthening	Weeks 3-8	Lift arm overhead with minimal discomfort
Return to activity	Weeks 8-12	Resume sports and overhead work tasks
Full recovery	3-6 months	Pain-free with full strength and range of motion

Most people achieve significant improvement with consistent exercise. The research backs this up. Patience and consistency beat intensity every time. In fact, one study found that gentle movement within pain-free ranges outperformed aggressive PT in the early stages (Diercks & Angevaren, 2004).
