shoulder impingement

Is caused by a mechanical dysfunction such as bursa, AC joint, acromion, humerus or rotator cuff/supraspinatus tendon beneath the coracromial arch. Clinically, the pectorals, posterior capsule and upper trapezius muscles are tight. Focus on training clients with SI, performing posterior capsule stretch, scapular retraction(mid row exercise) and external rotation strengthening to name a few.
