The Chest Muscles
The chest muscles are made up of the pectoralis major and, underneath that, the pectoralis minor.1 Together they are often referred to as the "pecs." The pectoralis major is the larger muscle and has two parts—an upper portion (called the clavicular head) and the lower portion (called the sternal head). The pectoralis minor is triangular in shape and works in tandem with the pectoralis major.

The chest muscles are responsible for moving the arms across the body and up and down, as well as other movements like flexion, adduction, and rotation. Most chest exercises involve pushing the arms away from the body or the body away from the arms.

Any chest exercise you do will work the entire area, but specific exercises will stimulate the chest in different ways.

Functional Fitness
The chest includes some of the largest muscles in the upper body and you use the chest muscles all day long. For example, the chest muscles are needed to push open a door, wash your hair, or get up and down from the floor. It's important to keep these muscles strong for all your daily activities. 

The stronger your chest muscles are, the stronger your entire body is.

You also use the pecs in many common exercises, such as the pushup. Your chest muscles are big and can handle more weight, which allows you to burn more calories when you exercise them. In fact, when you work your chest, your shoulders and arms are also involved, allowing you to exercise more of your body at once. A chest workout also serves as a great warmup for those smaller muscle groups.
