Shoulder pain and restriction often originate in the muscles surrounding the joint rather than the joint itself. The rotator cuff, scapular stabilizers, and chest muscles develop trigger points and fascial restrictions that limit shoulder mobility and create discomfort. A lacrosse ball reaches these tissues with precision, releasing the soft tissue component of many shoulder problems. The shoulder complex includes four joints that must work together for normal function. When surrounding muscles become restricted, this coordination breaks down. Lacrosse ball work addresses individual muscles, restoring the tissue quality needed for proper shoulder mechanics. Rotator Cuff Release Infraspinatus This muscle covers the back of the shoulder blade and externally rotates the arm. It is among the most common sites for shoulder-related trigger points, referring pain to the front and outer shoulder that mimics joint problems. Lie on your back with the ball positioned on the meaty portion of your shoulder blade. Locate the infraspinatus fossa, the depression below the spine of the shoulder blade. This is where the muscle bulk sits. Roll slowly across the muscle. Hold on trigger points for 45-60 seconds until tenderness decreases. Move your arm to different positions (overhead, out to the side, across the body) while on tender points to create pin-and-stretch effects. Spend 90-120 seconds per side. Supraspinatus This muscle sits above the spine of the shoulder blade and initiates arm lifting. It is frequently involved in shoulder impingement and rotator cuff issues. Position the ball in the depression just above the spine of your shoulder blade. This area is smaller than the infraspinatus region. Use a wall for better control of pressure. Apply moderate pressure and hold on tender points. This area often needs lighter pressure than other shoulder muscles. Spend 45-60 seconds per side. Subscapularis This muscle sits between the shoulder blade and ribcage, making it difficult to access directly. However, you work it indirectly through the armpit region. Stand with the ball between your armpit area and a wall. Position it toward the front edge of the shoulder blade. Apply gentle pressure and roll slowly, staying on muscle tissue rather than the armpit itself. This area is sensitive. Start with very light pressure. Spend 30-45 seconds per side.

Trigger points here cause aching between the shoulder blades and contribute to rounded shoulder posture. Lie on your back with the ball positioned about two inches from the spine, at the level of the shoulder blade. Hug yourself to spread the shoulder blades apart, exposing the rhomboids. Roll slowly up and down, holding on tender points for 30-45 seconds. Spend 90 seconds per side. Levator Scapulae This muscle runs from the upper shoulder blade to the neck. Trigger points here refer pain to the neck and upper shoulder, often contributing to neck stiffness. Stand with the ball between your upper shoulder blade region and a wall. Position it at the inside corner of the shoulder blade. Tilt your head away from the ball to increase stretch. Hold on tender points for 45-60 seconds. This area responds well to sustained pressure. Spend 60-90 seconds per side. Serratus Anterior This muscle wraps around the ribcage from the shoulder blade. Restrictions here affect scapular movement and overhead arm function. Lie on your side with the ball positioned on your ribcage, just in front of your shoulder blade. Roll slowly up and down, finding the finger-like muscle attachments between the ribs. This area is often tender. Use moderate pressure. Spend 60 seconds per side. Chest and Anterior Shoulder Release Pectoralis Minor This small muscle under the pec major connects the shoulder blade to the ribs. When tight, it pulls the shoulder forward and down, contributing to rounded posture and shoulder impingement. Lie face down with the ball positioned below your collarbone, in the space between your shoulder and chest. You should be slightly turned toward the ball side. Apply body weight pressure, starting light. This area often holds significant tension. Roll slowly and hold on trigger points for 60-90 seconds per side. Pectoralis Major The larger chest muscle often becomes tight and restricted, limiting shoulder mobility and pulling the shoulders forward. Stand facing a wall with the ball between your chest and the wall, near the shoulder. Roll slowly across the muscle from sternum toward armpit. Focus on the lateral portion near the shoulder, where the muscle attaches. Hold on tender points for 30-45 seconds. Spend 60-90 seconds per side. Anterior Deltoid The front of the shoulder often develops restrictions from pushing movements and forward posture. Stand facing a wall with the ball on the front of your shoulder. Apply gentle pressure and roll slowly. Stay on muscle tissue rather than bone. This area is sensitive and near important structures. Use light pressure. Spend 30-45 seconds per side. Complete Shoulder Routine (12 minutes) Infraspinatus (3 minutes): 90 seconds per side Rhomboids (3 minutes): 90 seconds per side Levator scapulae (2 minutes): 60 seconds per side Pec minor (2 minutes): 60 seconds per side Posterior deltoid/teres (2 minutes): 60 seconds per side Movement Integration After ball work, move your shoulders through their ranges: Arm circles: 10 each direction, each arm Shoulder shrugs and rolls: 10 each direction Cross-body stretch: 30 seconds each arm Doorway chest stretch: 30 seconds each position Programming Pre-workout: Brief work (3-5 minutes) on muscles that will be stressed during training. Post-workout: Thorough work (10-15 minutes) to address exercise-induced restrictions. Maintenance: Full shoulder routine 2-3 times weekly. Daily brief work on priority areas. For shoulder issues: Daily targeted work on problem areas until symptoms improve. Healthy shoulders require quality surrounding tissues. Lacrosse ball work maintains this tissue quality, supporting pain-free shoulder function. Start your free trial at simplmobility to build comprehensive shoulder health.
