How to pump up your pectoral muscles
Think of the pectoral muscle as a rubber band that connects your shoulder, collarbone, and sternum. If you raise your arm to the side and then pull the elastic, it will move your shoulder forward. You make this movement all the time in everyday life - for example, when you close a door, forcefully push something away, or hit your jaw with your elbow.
Most chest exercises repeat this movement. The only difference is that they also use a barbell, dumbbells or crossover straps to provide additional resistance.
The pectoralis muscle has two heads: superior (clavicular) and inferior. Their functions are slightly different, and that's important. To make your breasts symmetrical, you need to pump both heads.
The fibers of the clavicular head are directed upward, so for additional load you need to move the shoulder forward in the direction from bottom to top.
And in order to load the lower part of the pectoral muscle more, you need to move the shoulder moved to the side forward and down.
