subscapularis muscle

The subscapularis muscle is one of the four muscles that make up the rotator cuff in your shoulder. Located on the front of the shoulder blade (scapula), it helps you rotate your arm inward and stabilizes the shoulder joint during movement. Think of it as a key muscle that allows you to lift, reach, or throw with control. Its proper functioning is essential for shoulder strength and mobility, and issues with it can lead to pain or limited movement. Strengthening and maintaining this muscle supports overall shoulder health and performance.
