Roll Ball Infraspinatus Stretch
The Roll Ball Infraspinatus Stretch targets the infraspinatus, a key rotator cuff muscle responsible for shoulder stability and external rotation. Using a small ball, you apply controlled pressure to areas that commonly become tight from pressing movements, overhead work, or extended periods of sitting.
Shoulder internal rotation deficits are common among athletes who perform repetitive overhead or pressing movements, and targeted mobility work on the posterior shoulder helps restore balance and reduce injury risk (Moradi et al., 2020). Rolling and holding pressure on the infraspinatus reduces stiffness, improves blood flow, and restores normal shoulder movement patterns.
The posterior deltoid and rotator cuff muscles work together during shoulder function, and each responds to different types of stimulus (Franke et al., 2015). Self-myofascial release with a ball addresses tissue quality in a way that active exercises alone cannot, making it a valuable complement to any shoulder training program.
Perform this stretch regularly as part of warm-up or recovery routines. It supports healthier shoulder mechanics, improves range of motion, and helps maintain long-term shoulder function with nothing more than a small ball.

Technique and form
How to perform the Roll Ball Infraspinatus Stretch
- Lie on your side with your knees bent at a 90-degree angle and a small exercise ball beneath your top arm's shoulder joint.
- Position your top arm at shoulder height with your elbow bent at 90 degrees, keeping your forearm perpendicular to your torso.
- Roll your body weight slightly onto the ball, allowing it to press into the back of your shoulder where the infraspinatus muscle is located.
- Breathe deeply and relax into the position, maintaining contact between the ball and the targeted area just below your shoulder blade.
- Slowly extend your top arm forward while keeping pressure on the ball, intensifying the stretch in your infraspinatus muscle.
- Hold this extended position for 20-30 seconds while continuing to breathe normally, allowing the muscle to release tension.
- To increase the stretch, gently rotate your arm inward while maintaining the extended position and pressure on the ball.
- Return to the starting position and repeat 2-3 times before switching to the other side, maintaining core stability throughout the exercise.
Important information
- Adjust the ball position until you feel a targeted stretch in the back of your shoulder rather than discomfort or pain.
- Keep your neck in a neutral position throughout the exercise to prevent unnecessary strain.
- If you experience any sharp pain or tingling, immediately reduce pressure or stop the exercise.
- Make sure to breathe continuously during the stretch to help muscles relax and maximize the effectiveness of the stretch.

Benefits of the Roll Ball Infraspinatus Stretch
Muscles Worked: Roll Ball Infraspinatus Stretch
The Roll Ball Infraspinatus Stretch is a targeted self-myofascial release technique that focuses on the rear shoulders and lats. Here is how the tissue responds.
Primary target
Rear Delts — The ball applies focused pressure to the rear shoulders, releasing fascial restrictions and trigger points that cause tightness and limited movement.
Lats — The ball applies focused pressure to the lats, releasing fascial restrictions and trigger points that cause tightness and limited movement.
The Roll Ball Infraspinatus Stretch targets the rear shoulders and lats to restore tissue quality and reduce muscular restriction.
Risk Areas
FAQ - Roll Ball Infraspinatus Stretch
This stretch primarily targets the infraspinatus muscle in your rotator cuff, while also releasing tension in the rear deltoids and latissimus dorsi. These muscles often become tight from daily activities like desk work or from intense upper body training.
For best results, incorporate this stretch 2-3 times per week, holding each position for 20-30 seconds. Consistent practice leads to improved shoulder mobility and decreased upper back tension over time.
Yes, you can substitute a tennis ball, lacrosse ball, or even a rolled-up sock in a pinch. The key is finding something firm enough to apply pressure but soft enough to comfortably sink into the muscle tissue.
The most common errors include shrugging your shoulders toward your ears, overarching your lower back to compensate for limited shoulder mobility, and stretching too aggressively. Focus on quality over intensity, keep your core engaged to protect your spine, and remember that consistent, gentle stretching yields better results than occasional forceful attempts.
While this is generally a gentle stretch, consult with a healthcare provider before attempting if you have existing shoulder injuries or have recently had shoulder surgery. Start with very light pressure and stop immediately if you feel sharp pain or tingling sensations.
