What are pectorals?

In humans, the pectorals, also called the pectorals, are muscles found in the front upper part of a person's torso. The word pectoralis is generally used to refer to the pectoralis major, which is larger than the other pectoral muscle. The smallest muscle is called the pectoralis minor. The pecs are often the focus of weightlifting exercises and are quite easy to perform in a wide variety of exercises.

The pectoralis major muscle is thick and fan-shaped. In men, it makes up most of the upper chest. In women, this muscle is placed under the breast tissue. The pectoralis minor muscle is very different. It is thin, smaller and triangle-shaped.

An individual's largest pectoral muscle is important in movement. It acts on the humerus, the bone in the upper arm, when the shoulder has to move to pick up a child or throw an object to the side. It also helps in rotation of the humerus for movements needed in arm wrestling. Perhaps most importantly, it has the function of ensuring that a person's arm remains attached to their torso.

The smallest of the pectorals, the pectoralis minor has less to do with movement. Lower the tip of the shoulder and pull the scapula towards the chest, which is the part of the body that extends from the neck to the diaphragm, excluding the arms. This muscle helps an individual to shrug the shoulders forward.

There are many useful exercises to work the pectorals; among them are the basic push-ups. To perform a pectoral push-up, a person lies on the floor so that the front of the body is facing the floor and the hands, palms down, are resting on the floor. Then, extend your arms, keeping your knees straight and legs together. Finally, lower yourself back to the starting position. People sometimes have trouble doing push-ups and perform a variation of push-ups allowing their legs to bend and keeping their knees on the floor during the exercise.

Some people use weights to work their pecs. One of these exercises involves lying on your back on a weight bench and lifting a barbell from your rack. The athlete then lowers the weight to the mid-chest. Finally, he extends his arms and lifts the bar to his chest once more, repeating this movement several times.
