The pectoral muscles, commonly known as the "pecs," are a group of muscles located in the chest area. They consist of two main parts: the pectoralis major and the pectoralis minor. The pectoralis major is the larger muscle, responsible for movements such as pushing and lifting, while the pectoralis minor lies beneath it and helps stabilize the shoulder. These muscles play a crucial role in various physical activities, including sports and daily tasks. Strengthening the pectoral muscles can improve upper body strength and enhance overall fitness. Exercises like push-ups and bench presses are effective for targeting these muscles.
