Chest Exercises - Training & Workouts
For Huge Pecs!
The
chest muscles are made up of the pectoralis major and the pectoralis
minor. The pectoralis major is the bigger of the two and spans most
of the clavicle and sternum and attaches to the upper arm. It has
several important functions at the shoulder: flexion, adduction
(towards body), and medial (inward) rotation. The pectoralis minor
is a thin triangular muscle that lies beneath the pectoralis major
and is responsible for similar functions. Your chest is helpful
in contact sports that require a lot of pushing such as football
and rugby.
