The subscapularis is a large, triangular-shaped muscle that sits between the ribs and the scapula (wingbone). It is the largest and strongest of the four rotator cuff muscles and is responsible for stabilising the humeral head during motion and assisting with internal rotation of the arm. When the subscapularis becomes tight, weak or dysfunctional, it can cause pain in the neck, shoulder, ribcage and wrist, as well as affecting blood flow and nerves. To release a tight subscapularis, a combination of rest, activity modification, ice, physical therapy and massage can be used.

The subscapularis is a large, triangular muscle that sits between the ribs and scapula
The subscapularis is a large, powerful, triangular muscle that sits between the ribs and scapula. It is the largest and strongest of the four rotator cuff muscles, which are essential for shoulder movement and maintaining glenohumeral joint stability. The subscapularis muscle originates from the subscapular fossa, which is the medial and lower two-thirds of the groove on the lateral border of the scapula.
The muscle derives its name from its location under the scapula, with "sub" meaning under and "scapula" meaning wing bone. It is responsible for the internal rotation of the arm and assists in adducting the humerus. The subscapularis nerve innervates the muscle, and the subscapular artery provides its blood supply.
The subscapularis muscle is challenging to access for self-release, but it can be done. It sits between the front surface of the scapula and the back of the rib cage. When the subscapularis becomes tight, weak, or dysfunctional, it can cause pain in the neck, shoulder blade, tricep, bicep, elbow, wrist, and hand. This pain is referred to as pain from trigger points in the subscapularis muscle.
To release the subscapularis muscle, one can try foam rolling or massage therapy. Active Release Technique has been clinically proven to resolve impingement pain caused by subscapularis dysfunction. Massage of the subscapularis muscle should be done using the thumb technique, feeling the muscle contract, and then releasing the tension before beginning to massage. It is important to only massage the muscle and not the nerves.

It is the largest and strongest of the four rotator cuff muscles
The subscapularis is the largest and strongest of the four rotator cuff muscles. The other three rotator cuff muscles are the supraspinatus, infraspinatus, and teres minor. The subscapularis is a large triangular-shaped muscle that sits between the front surface of the scapula and the back of the rib cage. It is a powerful internal rotator of the arm, and it assists in stabilizing the humeral head during motion. When the arm is raised, the subscapularis pulls the humerus forward and downward, and it also adducts the arm to a lesser extent. This muscle is an important stabilizer of the shoulder joint, especially when the deltoid, pectoralis major, biceps, and triceps brachii muscles are active.
The subscapularis may include up to three trigger points, with two common points occurring near the outside edge of the muscle. Referred pain from these trigger points concentrates in the posterior shoulder region, with spillover into the shoulder blade region and down the back of the upper arm. A unique ""band" of referred pain around the wrist may also occur. An overworked subscapularis can cause a person to feel unable to lift their arm and may even result in a frozen shoulder.
To treat subscapularis tendonitis and tendinopathy, rest, activity modification, ice, analgesia, and physical therapy are recommended. Massage of the subscapularis muscle can be beneficial, but it is important to avoid massaging the nerves. Active Release Technique has been shown to resolve impingement pain caused by subscapularis dysfunction. This technique involves assessing the length of the muscle and tensioning the lesion in a slackened position while the arm is taken through a range of external rotation and elevation to release the adhesion.

When the subscapularis is tight, it can cause pain in the neck, shoulder and ribcage
The subscapularis is the largest and strongest of the four rotator cuff muscles. It is a large, triangular-shaped muscle that sits between the front surface of the scapula (the wingbone or shoulder blade) and the back of the ribcage. It is responsible for internally rotating the arm and assisting with arm-reaching, -pulling, and -lifting activities.
When the subscapularis becomes tight, weak, or dysfunctional, it can cause pain in the neck, shoulder, and ribcage. This is due to the muscle's proximity to the shoulder blade and ribs, which can affect the movement of the shoulder blade over the ribs. If the subscapularis is tight, it can cause the ribcage to stiffen up and place excessive strain on the rib and shoulder joints, leading to pain in the upper back, neck, and/or shoulder.
Additionally, the subscapularis has trigger points or "knots" that can decrease circulation and change the brain's perception of the muscle's health. These trigger points can cause referred pain in the neck, behind the shoulder blade, in the tricep/bicep, along the outside of the elbow, or down in the wrist and hand.
To release a tight subscapularis, one can try self-release techniques such as foam rolling or seek professional help through physical therapy, massage therapy, or aerial fitness. It is important to address the underlying cause of the tightness to achieve long-term relief.
If you are experiencing pain or discomfort in the neck, shoulder, or ribcage, it is recommended to consult with a healthcare professional for a proper diagnosis and treatment plan.

Trigger points in the muscle can be released with a foam roller
Trigger points in the subscapularis muscle can be released with a foam roller, but it is important to understand the muscle and its role first. The subscapularis is a large, triangular-shaped muscle that forms the largest and strongest part of the four rotator cuff muscles. It is responsible for internal rotation of the arm and plays a vital role in stabilising the shoulder joint. When the subscapularis becomes tight, weak, or dysfunctional, it can cause pain in the neck, shoulder blade, tricep, bicep, elbow, wrist, and hand.
To release the subscapularis with a foam roller, lie down on your side with the roller under the muscle you want to release. Adjust your body position to apply pressure to the muscle, and use your legs and free arm to control the pressure. Gently roll the foam roller around the area, focusing on any tight spots you feel. As you roll, internally and externally rotate your arm to help target tight areas within the muscle fibres. Spend 1-2 minutes on each side, or until you feel the muscle release and tension subside.
It is important to note that releasing a tight subscapularis may not be a comfortable process, and you may experience some discomfort. However, with frequent massages, you should be able to work more effectively in the area without pain. Additionally, while foam rolling can help restore normal motion and alleviate pain, it may not be a permanent solution for those with chronic shoulder issues. If symptoms persist or keep returning, it is recommended to seek a professional assessment by a skilled physical therapist.
Other techniques for releasing the subscapularis include using your fist or a massage ball. To use your fist, sit on a chair and lift the arm on the side of the subscapularis you want to release to shoulder height. Make a fist with your opposite hand and place it under your armpit, pressing it into the side of the subscapularis muscle. Rest your elbow on your thigh and lean forward slightly to increase the pressure. Gently massage the area in small circular motions, focusing on any tight spots. As you massage, internally and externally rotate your arm to target tight areas within the muscle fibres.

Massage the subscapularis with a thumb technique, then release tension and massage
The subscapularis is the largest and strongest of the four rotator cuff muscles. It is a large, triangular-shaped muscle that sits between the front surface of the scapula and the back of the ribcage. When the subscapularis is dysfunctional, it can cause shoulder pain and impair the biomechanics of the shoulder. It can even lead to a frozen shoulder.
To release and massage the subscapularis muscle, you can use a thumb technique. First, locate the subscapularis muscle by placing your hand on your back in the lumbar area. If you are unable to lift your hand off your back by further internal rotation of the arm, this suggests an injury to the subscapularis muscle.
Once you have located the subscapularis muscle, use your thumb to apply precise massage strokes or a pressure-motion technique. Search for tender spots in the muscle and, if needed, tense the muscle by performing a medial rotation to make it easier to massage. Press into the muscle and move your arm through various positions, such as lifting, lowering, and rotating. Concentrate on the painful ranges of motion.
After massaging the subscapularis muscle with your thumb, release the tension and start to massage it with your hand. Make sure you only massage the muscle and not your nerves. You can also try a self-soft tissue mobilization technique using a broomstick or dowel with a towel wrapped around one end. Place the towel on a tender spot on the subscapularis muscle and apply medium pressure. Slowly internally and externally rotate your shoulder while it is raised up beside you.
