The deltoid is a triangular shaped muscle that attaches at the spine and lateral third of the clavicle. It can be divided into three parts: anterior (front), lateral (side), and posterior (rear). When all three parts are contracting simultaneously, the deltoid can help abduct the arm past 15 degrees.
Throughout abduction, the anterior and posterior parts of the deltoid play an important role in stabilizing the arm. If you’re looking to raise your arm above 15 degrees, the lateral head also helps with this process. When walking, the anterior head of the deltoid moves your arm forward. This contrasts to the posterior part of the deltoid which works with a different muscle group to extend your arm when walking.
