what are pecs muscle

Pecs muscles are the chest muscles, mainly the pectoralis major and pectoralis minor. They sit on the front of your upper chest and help move your arms and shoulders, especially for actions like pushing, bringing your arms inward, and rotating the upper arm.

Quick Scoop

• Pectoralis major : the large, visible chest muscle that makes up most of the “pecs”.

• Pectoralis minor : a smaller muscle underneath the major, also part of the chest wall.

• Main jobs : arm adduction, shoulder movement, and helping with pushing motions like bench press or push-ups.
