What is a Pectoral Muscle?
The pectoral muscle is often referred to as the “pecs” or “chest muscles.” It is a large muscle located on the chest of the human body. The muscle attaches to the clavicle, ribs, and sternum.
The pectoralis major originates from three parts: 1) clavicular origin, 2) sternocostal part, 3) costal origin. The sternocostal part originates from the cartilage of rib 2-5. The clavicular origin develops from cartilage of ribs 3-6 and inserts on humerus at tubercle of upper arm bone. The costal part arises from cartilage between ribs 8-11 and inserts at humerus along with sternocostal part.
Right vs Left Pectoral Muscles – Which Is More Important?
Our right and left pectoral muscles work together to keep our upper body in balance. The right pectoral muscle is more important as it helps us maintain our posture and balance.
The right pectoral muscle, also known as the “stabilizer” muscle, is the bigger of the two and is more important for maintaining balance. It holds up the entire upper body when we are upright or supine, by providing stability in all directions. It provides stability when we are walking, running or jumping.
The left side of your chest muscles play an important role in balancing your upper body. They are smaller but just as important as the right side pectoral muscle as they provide stability when you are lying on your left side or turning your head from one side to the other.
How to Perform a Bench Press and Why It’s Important
You can find a bench press machine in most gyms, and the exercise is a staple of weightlifting. But how do you perform a bench press? And what is the benefit of performing it?
In order to perform a proper bench press, lie on your back with your feet flat on the floor and grip the barbell with palms facing away from you. Take a deep breath and use your legs to push up from lying down into an extended position. Slowly lower yourself back down to lying down and repeat as many times as you need for desired reps.
The benefits of doing this exercise are numerous: it builds muscle in the chest, triceps, and shoulders; strengthens abdominal muscles; improves posture; and it also works out the lats (back).
