为什么会不舒服

平板卧推、夹胸加得太急；含胸让这一大束一直处在缩短位。

常见不适表现

胸口正中两侧酸、发紧；向后展开双臂时胸口被拉住。

Sternocostal pectoralis major

Front of the chest · Common, after training

What this muscle is

The largest part of pectoralis major, from the breastbone and the rib cartilages to the humerus. Pushing relies mainly on it.

Why it gets uncomfortable

Bench press and flyes added too fast; a collapsed chest that keeps this large part shortened.

How it usually feels

Sore and tight on both sides of the middle of the chest; the chest is held back when you open both arms backward.

What helps

Forearms on a door frame, elbows level with the shoulders, and shift the body forward. Hold 20 seconds. If the chest stabs or you are short of breath, see a doctor first. Do not keep stretching.
