CHEST ANATOMY

The pectoral muscle sticking out of the shirt with stripes across the chest with the line that differentiates in the middle of the chest.

Is the dream of all of us.

But fortunately, dreams are meant to be fulfilled.

With correct work according to the anatomy we will be able to maximize our training on the chest muscles.

Brief anatomy:

The pectoral muscle is one large muscle [PECTORALIS MAJOR] with three muscle fibers in different directions.

All three are connected to the sternum bone which is located in the middle of the body.

And all three reach the humerus.

Every exerciser knows that training on a muscle is according to the direction of the fibers of the muscle, so this is also the case here.

Upper fibers will work more in a bottom-up lift like an incline bench press.

Medium fibers will work more on bench press without incline or cable fly.

Lower fibers will work more in a top-down lift, such as a cable fly for the lower chest.

Note: all chest fibers will work, especially in bench pressing without an incline, but in order to maximize the training on the chest it is important to emphasize all fibers.
