Wellness Wednesday - Cross Body Deltoid Stretch

Last week we went over an effective tricep stretch. Today, keeping with the upper body, we will go over an easy cross body deltoid stretch. The deltoid is the muscle of our shoulder. It is comprised of three sections, all performing various movements of the arm. 

The deltoid muscle originates from the lateral part of the clavicle (collarbone), as well as the spine and acromion process of the scapula (shoulder blade). From these points of origin, the muscle then travels down the arm and inserts on the deltoid tuberosity of the humerus (long bone of the upper arm).

The anterior deltoid assists the pec major to flex the shoulder. The anterior deltoid also works in tandem with the subscapularis, pecs and lats to medially rotate the humerus. 

The lateral deltoid performs basic shoulder abduction when the shoulder is internally rotated, and perform shoulder transverse abduction when the shoulder is externally rotated. 

The posterior deltoid assists the latissimus dorsi to extend the shoulder. Other transverse extensors, the infraspinatus and teres minor, also work in tandem with the posterior deltoid as external rotators, antagonists to strong internal rotators like the pecs and lats.

  1. Take one arm and extend it across your body. 


  1. Gently press and pull your extended arm to deepen the stretch.

This is a great stretch we hope you take time to do at your desk today. Shoulder muscles don’t get stretched out often enough and we want to make sure we take the time to take care of all parts of our bodies. 

Next week we will take on a side stretch!
