Are your shoulders rounding forward from desk work? This side-lying passive stretch targets the pectoralis muscles. By stabilizing the scapula and guiding the arm upwards and backwards into external rotation, we release deep tension in the chest and anterior shoulder to improve posture. 😮 Send this to someone with chronic shoulder tightness. #bodywork #mobility #posturecorrection #cheststretch #manualtherapy #thoracicspine #shouldertension
