Shoulder impingement syndrome occurs when the structures in the shoulder-most commonly the rotator cuff tendons-get compressed between the upper arm bone and the acromion during movement. This irritation leads to pain when lifting the arm, reaching overhead, or lying on the affected side. Improving shoulder mobility, strengthening the rotator cuff, and correcting posture (especially rounded shoulders and a tight chest) are key for reducing impingement. These strategies create more space in the j
