Stretching Pectoralis Muscles - Dr. Jonathan Kuttner
The pec major eccentrically decelerates extension, horizontal abduction, external rotation, and retraction of the shoulder joint.
This muscle can develop multiple myofascial trigger points because of its clavicular and sternal fibers, firing pain across the anterior deltoid and down the lateral aspect of the arm into the thumb and fourth and fifth digits.
A rare myofascial trigger point can mimic the symptoms of angina pectoris. Pain from these myofascial trigger points can also be felt as interscapular and subscapular pain.
Here's our favorite stretch for the pec major. We often recommend this stretch in clinic, as it's easy to perform, and works simultaneously on pec minor, anterior deltoid, biceps brachii, brachialis, brachioradialis and coracobrachialis.
Stand with your arm extended to the rear and parallel to the ground. Hold on to an immovable object and then turn your shoulders and body away from your outstretched arm.
Keep your arm parallel to the ground and your fingers pointing backwards.
