The Sneaky Effects of a Tight Pec Minor

When the pec minor is tight, it pulls the shoulder blade forward and downward, contributing to rounded shoulders and potentially compressing nerves that run into the arm.

Common symptoms of a tight pectoralis minor include:

This tightness also leads to altered scapular kinematics, meaning the shoulder blade’s movement patterns become dysfunctional.

This throws off the delicate rhythm between the scapula, pec muscles, and back muscles like the trapezius and levator scapulae.

Over time, it can affect everything from arm strength to breathing due to its influence on the rib cage.

Frequently Asked Questions

How do you release a pectoralis minor?

You can release the pec minor through stretching, self-myofascial release (e.g., with a lacrosse ball), manual therapy, or targeted exercises like doorway or corner pec stretches.

What causes the tight pec minor?

 Common causes include poor posture (especially forward head and rounded shoulders), overuse from activities like bench pressing, or prolonged sitting and slouching.

Do dips stretch the pec minor?

Not effectively. Dips primarily target the pec major, triceps, and anterior deltoid. They may actually tighten the pec minor if shoulder positioning is poor.
