Looking to develop a stronger and more defined lower chest? Check out the most effective movements for building your chest muscles. The chest, also known as the pectoral region, consists of several muscles that play a crucial role in shoulder and upper arm movements. These muscles work together to help move the arms and shoulders, stabilize the shoulder girdle, and perform activities like pushing, pulling, and lifting. A strong chest is important for upper body strength, posture, respiratory function, and overall appearance. Incorporating exercises that target the chest muscles can help you achieve these benefits.
