Release your chest to help your back

Anatomy of a muscle

The pectoralis major is a large muscle located near the skin in front of the rib cage. It originates on the clavicle, the sternum, and the top of the abs. It runs across the chest to the insert on the upper arm. The muscles actions include:

  • moving the arm into horizontal adduction (arm comes across the body);

  • internal rotation of the arm (turning the pages of a book that is on your lap);

  • shoulder adduction (raising your arm out to your side); flexion of the arm (raising your arm in front of you)

Causes of tightness

The pectoralis major is shortened by bad posture habits, such as hunching over or working with your arms extended in front of you. Hairdressers, massage therapists, and people who work with laptop computers are often affected.

Symptoms of tightness

  • Vulture-neck posture (head juts out in front of the body)

  • Pain or muscle spasm between the shoulder blades

  • Pain across the sternum

  • Pressure across the chest

  • Tingling or numbness in the arms, especially at night

Check if for tightness through this flexibility test

  • Hold a pencil in each fist

  • With your arms by your sides, bend over slightly at the hips and shake out your shoulders

  • Stand up and look at the pencils

  • If they are pointing toward each other, you have a tight chest

The fix

  1. Lie on the ground on your stomach

  2. Your arm should be down by your side (It can be out to your side if tolerated)

  3. Place a tennis ball or lacrosse ball under your chest on one side of your sternum

  4. Find a tender spot and hold 30 seconds to 2 minutes or until there is just pressure, no pain

When you are finished, there should be some improvement in the range of motion. Take the pencil test again to verify.

Now you're ready to strengthen the muscles between the shoulder blades to keep your shoulders aligned permanently. The Hands-Free Middle Back Strengthener is an easy-to-use device that can be done anywhere. And it only takes 2 minutes a day! Get yours here.
