The chest muscles could be considered a defining part of strength anatomy. They are involved in actions such as squeezing a set of loppers to cut a tree branch and pushing a door open. They are also the primary muscles referenced when debating upper body strength.

this variation, the bench should be angled upward between 45 and 60 degrees, so you are leaning back slightly. It targets muscles of the upper chest and shoulders.

2 traditional chest press

This exercise is done lying down on a flat bench and pressing a barbell up and down at chest height. It works the pectoral muscles, shoulders, and arms.

3 Decline chest press

this variation, the bench should be angled downward, so when you lie down your feet are in a higher position than your head. It works the lower chest muscles and shoulders.

4 Chest butterfly

The chief muscle worked during the butterfly exercise is the sternal portion of the pectoralis major, according to ExRx.net, a physical therapy and training website. This muscle makes up most of your chest wall and not only adds definition to your chest, it also works with the shoulder muscles and joint to rotate the arm inward and outward.
