Clavicular pectoralis major

Upper front of the chest · Common, after training

What this muscle is

The part of pectoralis major that starts on the collarbone and reaches the humerus. It lifts the arm forward and draws it inward.

Why it gets uncomfortable

A lot of incline pressing; this bundle under the collarbone shortens when the shoulders round; the arms forward all day.

How it usually feels

Tight from under the collarbone to the front of the shoulder; a pulling pain when the arm opens back and down.

What helps

Forearm on a door frame, elbow below the shoulder, and lean the body slowly forward until it opens under the collarbone.
