The pectorals are muscles in the upper front part of the torso, with the pectoralis major being the largest and the pectoralis minor being the smallest. They are important in movement and can be worked through exercises such as push-ups and weightlifting.
In humans, the pectorals, also called pectorals, are muscles found in the front upper part of a person’s torso. Usually, the word pectoralis is used to refer to the pectoralis major, which is larger than the other pectoralis muscle. The smallest muscle is called the pectoralis minor. The pecs are often the focus of weightlifting exercises and are easy enough to work through a wide variety of workouts.
The pectoralis major muscle is thick and shaped like a fan. In men, it accounts for most of the upper chest. In women, this muscle is positioned under the breast tissue. The pectoralis minor muscle is very different. It is thin, smaller and shaped like a triangle.
An individual’s largest pectoral muscle is important in movement. It works on the humerus, the upper arm bone, when the shoulder has to move to lift a child or throw an object to the side. It also aids in the rotation of the humerus for the movements needed during arm wrestling. Perhaps more importantly, it is responsible for ensuring that a person’s arm stays connected to their trunk.
The smallest of the pecs, the pectoralis minor has less to do with movement. Bring the point of the shoulder down and move the shoulder blade toward the chest, which is the part of the body that extends from the neck to the midriff, excluding the arms. This muscle helps an individual shrug their shoulders forward.
There are many exercises that are useful for working the pectorals; among them are basic push-ups. To perform a push-up to work the pecs, a person lies down on the floor, so the front of their body faces the floor and their hands, palms down, are flat on the floor. He then extends his arms, keeping his knees straight and legs together. Finally, he lowers himself back to the starting position. Sometimes people find it difficult to do pushups and instead do a variation of them, allowing the legs to bend and keeping the knees on the floor during the exercise.
Some people use weights to work their pecs. One such exercise involves lying on your back on a weight bench and lifting a barbell off the rack. Then, the exerciser lowers the weight toward the center of the chest. Finally, extend your arms and lift the barbell to your chest once more, repeating this movement several times.
