Common muscle imbalance – pec minor dominates lower traps
A common muscle imbalance in the body is pec minor dominates or overpowers lower trapezius.
Pec minor is a muscle that sits on the anterior wall of the chest and affects the movement of the scapula (shoulder blade). Tightness in the pec minor will lead to anterior tilting and downward rotation of the scapula and prevent full upward rotation, elevation and posterior tilting of the scapula which is required for full shoulder elevation.
Tightness in pec minor can therefore, contribute to shoulder injuries such as shoulder impingement, rotator cuff pathologies, glenohumeral instability, internal impingement, adhesive capsulitis, to name a few. Read more
