Cleavage muscle refers to a specific muscle group in the human body that is located in the upper chest region. It is a colloquial term often used to describe the distinct muscle definition or separation that occurs between the pectoralis major muscles, commonly known as the "pecs".
The cleavage muscle is situated in the center of the chest and plays a significant role in shoulder and arm movements, primarily assisting in their flexion and adduction. It is responsible for allowing individuals to perform a variety of everyday tasks, such as pushing, pulling, and lifting heavy objects.
This muscle group is formed by the thick bundles of muscle fibers that make up the pectoralis major, which can become visible and well-defined with proper training and conditioning. Many individuals aim to develop a prominent cleavage muscle as it is often associated with strength, athleticism, and aesthetic appeal.
To strengthen and enhance the appearance of the cleavage muscle, various exercises can be performed, including bench presses, push-ups, chest flyes, and dumbbell presses. These exercises specifically target the pectoralis major, contributing to increased muscle size and definition.
Overall, the cleavage muscle is a visual representation of the well-developed pectoralis major muscles, often sought after by individuals aspiring to build a robust upper body.
