The pectoralis (pec) muscles are large, highly visible muscles located on each side of the chest. Their primary job is help the shoulders and arms move and lift. When you perform a push-up or chest fly, you are activating the pecs. Because they are among the strongest muscles in the body, they are less likely to be strained (pulled), but it can happen. Dave Cruz. Grade 1 strains involve a few torn muscle or tendon fibers.
The pectorals are predominantly used to control the movement of the arm, with the contractions of the pectoralis major pulling on the humerus to create lateral, vertical, or rotational motion. The pectorals also play a part in deep inhalation, pulling the ribcage to create room for the lungs to expand.
