Apart from training your primary chest muscles, you should know the secondary muscles in the chest.

Types of secondary muscles for chest exercises

Muscles in the chest region are termed push muscles. Push muscles are the muscles that contract when weight is pushed away from the body. To support the pectoral (chest) region’s primary muscles, a group of secondary muscles, whose main purpose is to help primary chest muscles perform their function smoothly.

The main secondary muscles of the chest are of two types; deltoids and triceps.

1.    Deltoids:

Present in the uppermost part of the arm, the deltoid is a triangular muscle. Its name comes from the Greek word ‘delta,’ which is similar to the equilateral triangle. It originates from three regions: the clavicle (collar bone), acromion of scapula (shoulder blade), and spine of the scapula, whereas it is inserted in the humerus (upper arm bone).

Function: Deltoid performs three distinct functions corresponding to the three bands of the fibers. The anterior fiber of the deltoid acts along with a pectoralis major to flex the arm’s flexion in running or walking motion.

On the other hand, the deltoid’s posterior fiber helps extend the arm during ambulation and latissimus dorsi. Moreover, it also helps with the external rotation of the humerus. It helps to strengthen muscles and offset the shoulder’s tendency to rotate internally due to poor posture.

2. Triceps:

The second set of secondary muscles that help the primary muscles of the chest is the triceps. These are present in the upper part of the arm. They run along the humerus between the shoulder and elbow. It has three separate bony origins and then comes together to a common insertion point.

Its long head originates from the scapula, the medial head originates from the inferior of the radial groove, and the lateral head originates from the superior of the radial groove. The triceps is the primary extensor of the forearm.

Functions: The primary purpose of the triceps is to help the forearm with the extension or movement. Moreover, they act as an antagonist of the biceps and brachialis. They help to keep the head of the humerus in the correct position to stabilize the shoulder.

How secondary muscles affect chest exercises:

We concluded that without secondary muscles, primary muscles would not be able to perform their function. Thus, when you are trying to have a bigger chest and planning your lifts, you should not ignore secondary muscles.

Building and strengthening secondary muscles is as important as building primary muscles in the chest. So, you must also include lifts that can build these secondary muscles.

Anatomy of the chest

The chest or pectoral region lies between the neck and abdomen. When one looks at the chest’s anatomy, you will notice it is divided into three parts. The upper part is called clavicular, the middle region is called sternocostal, and the lowered part is known as the abdominal head.

However, when it comes to muscles, they are usually categorized into two categories; upper muscles make up the clavicular head, and the lower muscles constitute the sternocostal and abdominal head.

The primary function of the muscles in the chest region is to help the upper body in movement.

Pectoralis major, pectoralis minor, serratus anterior, and subclavius. Among these four, the pectoralis major is the most massive muscle present in the chest’s upper part. These four primary muscles help shoulder blades and arms move forward, backward, or move in any direction.
