The Pectoralis Major

The Pectoralis Major is a muscle well loved by those who are into fitness, but is also a complex and convoluted muscle, much abused and often hypertonic.

The anatomy of the muscle is actually more complex than it first appears because the Pectoralis Major is a structure consisting of sheets, similar to a fan- positioned deck of cards, wrapped around the origin at the armpit.
