When we look closely at the shoulders’ anatomy, it consists of two main muscles; Deltoids and Rotator Cuff Group.

Deltoids:

The Deltoids can be seen outside 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

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

Lateral

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

Posterior

Regarding the structural stability of the shoulders, posterior deltoids play a crucial role. There is a misconception that posterior deltoids are involved in back exercises, but it is not valid. This muscle also helps with the transverse abduction.

Rotator Cuff:

As its name indicates, the rotator cuff helps you rotate your shoulders in all directions. Moreover, these muscles play a crucial role in stabilizing the movement of shoulder joints. Rotator cuff muscles further consist of four muscles. These include:

Infraspinatus

In the back of the shoulder, it is attached to the head of the humerus. The Infraspinatus helps your arms and shoulders to move and stay stable.

Supraspinatus

It is a relatively more minor muscle than infraspinatus and is present in the upper back. The Supraspinatus 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. The Teres Minor 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. The Subscapularis is the most massive muscle of the rotator cuff group, which helps attach your upper arm to the shoulder.
