The Pec Deck, also known as the butterfly machine, is a popular exercise machine that targets the chest muscles. It is a great way to build strength, size, and definition in your chest muscles. But do you know which muscles are worked during this exercise? In this article, we will discuss the muscles worked during the Pec Deck exercise in detail.
The Chest Muscles
The chest muscles, also known as the pectoralis major and minor, are the primary muscles worked during the Pec Deck exercise. These muscles are responsible for the movement of the upper arm towards the center of the chest. They are divided into two separate muscles: the pectoralis major and the pectoralis minor.
The pectoralis major is the larger of the two muscles and is responsible for the majority of the movement during the Pec Deck exercise. It is a thick, fan-shaped muscle that covers the upper part of the chest. The pectoralis minor is located underneath the pectoralis major and is responsible for stabilizing the shoulder blade.
The Anterior Deltoid
The anterior deltoid, also known as the front deltoid, is a muscle located at the front of the shoulder. This muscle is also worked during the Pec Deck exercise. It is responsible for lifting the arm in front of the body and is activated during the movement of the upper arm towards the center of the chest.
The Triceps
The triceps, located at the back of the upper arm, are also worked during the Pec Deck exercise. They assist in the movement of the upper arm towards the center of the chest and are responsible for extending the elbow joint.
The Biceps
The biceps, located at the front of the upper arm, are also involved in the movement during the Pec Deck exercise. They act as stabilizers during the movement and are responsible for flexing the elbow joint.
The Serratus Anterior
The serratus anterior, located on the side of the chest, is also worked during the Pec Deck exercise. It is responsible for stabilizing the shoulder blade and assisting in the movement of the upper arm towards the center of the chest.
The Rhomboids
The rhomboids, located in the upper back, are also involved in the movement during the Pec Deck exercise. They are responsible for retracting the shoulder blade and stabilizing the upper back during the movement.
The Latissimus Dorsi
The latissimus dorsi, commonly known as the lats, are large muscles located on the back. They are responsible for pulling the upper arm towards the body and are also involved in the movement during the Pec Deck exercise.
Conclusion
The Pec Deck exercise is a great way to target and strengthen the chest muscles. However, it also involves several other muscles that work together to perform the movement. By understanding which muscles are worked during this exercise, you can tailor your workout to target specific areas and achieve your fitness goals.
