The term "Pecs" refers to the pectoral muscles, which are located in the chest area. These muscles play a crucial role in various movements, such as pushing and lifting. The pectoralis major and pectoralis minor are the two main muscles that make up the Pecs, contributing to upper body strength and stability. Strength training exercises, like bench presses and push-ups, are commonly used to develop the Pecs. Well-defined Pecs are often associated with physical fitness and are a common goal in bodybuilding and fitness routines. Maintaining strong Pecs can also improve posture and overall upper body functionality.
