The chest is made up of muscles called the pectorals. The main ones are the pectoralis major and minor. When you do chest exercises, these muscles help move your arms and shoulders. Your triceps (back of the arm) and shoulders assist in most chest moves too. Knowing which muscles are involved helps you focus on proper form and muscle engagement.
These moves prepare your muscles and joints for intense activity and reduce injury risk.
That’s it. No need for weights or gym machines.
