anatomy of shoulders

What is the anatomy of the shoulders, and how to use it to build muscles? What is sexier than getting perfectly toned and defined muscles. Many people spend hours in the gym but still are unable to get results. To get an ideal body, try to give the right focus to each muscle group separately.

Therefore, in this article, we will explain how to build shoulder muscles in light of its anatomy.

The anatomy of the shoulders

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

     I.         Deltoids:

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 shoulder’s anterior side, 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 muscle’s head. Bodybuilders need to build these muscles for an aesthetic look. Its primary function is shoulder abduction.

Posterior Deltoid:

When it comes to the structural stability of 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.

  II.         Rotator Cuff:

The rotator cuff, as its name indicates, helps you to 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:


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.


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.


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.

How to build shoulder muscles

Once you have learned about the shoulders’ anatomy, it would be easy to identify the best shoulder exercises to build the shoulder muscles.

The best shoulder exercises in light of the anatomy of the shoulder:

Some special exercises and workouts specifically target your shoulder muscles and help them to grow. These include:

  • Barbell or dumbbell shoulder press
  • Seated side lateral raise
  • Upright rows
  • Single-arm lateral raise
  • Side lateral to front raise
  • Barbell push-up
  • Standing military press

In final words, what is the shoulders’ anatomy and how to use it to build muscles?

The key to getting powerful, broad shoulders is to do all the exercises correctly. Therefore, choose the targeted exercises for the shoulders to achieve your desired results.
