Deltoids can be seen on the outside of the body and provide width to the upper body. Moreover, its deltoids contribute to the V-taper physique. Deltoid muscles further consist of three main parts. These include:

Anterior Deltoid:

The anterior deltoid is responsible for contracting the anterior side of the shoulder, thus helping in the arms’ forward movement. Besides, it helps with the transverse adduction using pectoralis major muscles (chest muscles).

Lateral Deltoids:

Lateral deltoids are responsible for the upper body structure’s overall width and are the head of the muscle. Bodybuilders need to build these muscles for the aesthetic look. Its primary function is the shoulder abduction.

Posterior Deltoid:

Infraspinatus:

Present in the back of the shoulder, it is attached to the head of the humerus. It helps your arms and shoulders to move and stay stable.

Supraspinatus:

It is a relatively smaller muscle than infraspinatus and is present in the upper back. It is separated from the infraspinatus through the spine of the scapula. Moreover, it helps the shoulder with the abduction movement.

Teres Minor:

It is a small, narrow, and intrinsic shoulder muscle. It originates from the lateral border of the scapula and ends at the tubercle of the humerus. Its primary function is to help the shoulder to rotate externally.

Subscapularis:

It is a sizeable triangular-shaped muscle and helps to move your shoulder internally. It is the most massive muscle of the rotator cuff group, which helps attach your upper arm to the shoulder.
