The Pectoralis Minor is a shy little fella hiding under the Pectoralis Major.
It originates from the 3rd-5th ribs, where the rib connects to the cartilage.
It’s composed of three muscular branches that connect and insert together in the scapula (coracoid process).
It makes 3 actions:
🔹Scapula protraction with downward rotation.
🔹Stabilizes the scapula.
🔹When the scapula is fixed: It raises the ribs and thus helps in inhalation.
Weakening of the Pectoralis minor may cause increased respiratory difficulty for people who already experience difficulty in this breathing.
It’s a muscle that gets easily shortened, which may lead to rounded shoulders and bad posture, and limit the shoulder flexion range.
So it’s crucial to stretch it!
