Understanding Chest Muscle

The technical name for chest muscles is the pectorals, but you can shorten the term to pecs. You have two pec muscles:

• Pectoralis major: The pec major is a skeletal muscle that draws the arm inward and rotates it. This muscle enables you to give hugs. Whenever you pledge allegiance, your hand is covering the meat of the pectoralis major.
• Pectoralis minor: The pec minor moves the scapula forward and down and also raises the ribs. This muscle resides underneath the pec major. Figure shows the location of your pectorals. With the help of other muscles, such as your shoulder muscles and triceps, your pecs are in charge of a variety of pushing and hugging movements.
