Trigger points (TrPs), or muscle “knots,” are a common cause of stubborn & strange aches & pains, and yet they are under-diagnosed. The 14 Perfect Spots (jump to list below) are trigger points that are common & yet fairly easy to self-treat with massage — the most satisfying & useful places to apply pressure to muscle. For tough cases, see the advanced trigger point therapy guide.

The “pecs” are popular: of 700+ muscles, the pectoralis major is one of just a dozen or so that most people can name and point to. It also harbours one of the most commonly-encountered and significant trigger points in the human body, and can produce pain much like a heart attack in both quality and intensity. And yet it’s little known.

Pectoralis major basics: the hugging muscle

The pectoralis major covers the top half of your chest. It is mostly an arm mover, although it also stabilizes the joint between your sternum and collar bone. It is the hugging muscle: it powerfully pulls and rotates the arms towards the center of your body.

Like all the big flexors, it’s crazy strong. The pectoralis major is so large that it can always do its job with at least some of its fibers, no matter what position the shoulder is in.

(The pectoralis minor, by the way, is quite a different muscle. As its name suggests, it is much smaller. It is completely covered by the pectoralis major, and does not move the arm at all!)

A manly muscle: the pectoralis gender gap

The pectoralis major is also, interestingly, one of the only muscles in the human body that is almost always much larger in men than it is in women, which accounts for much of the difference in upper body strength between the genders. Even the strongest women usually have relatively thin pectoralis major muscles — something I learned from massaging thousands of people during my massage therapy career.

Regardless, Perfect Spot No. 9 is a good massage location for both men and women.

Where is Perfect Spot No. 9?

Spot No. 9 is easy to find by touch: it’s on the edge of a distinctive pocket or hollow directly underneath your collarbone. The pocket is a small, unmuscled space between the deltoid and the pectoralis major. If you explore right below your collarbone, it is easy to find the soft spot between these two large muscles. Once you’ve found it, press towards the sternum against the edge of the hollow — that’s pectoralis major you’re pressing — and you’ve found Perfect Spot No. 9.

How to massage Spot 9

Thumb pressure is often adequate to stimulate this spot, but many people — especially men, with their larger pectorals — may need knuckles or even an elbow to get a clear “signal.”

Although No. 9 is a specific spot on the edge of the pectoralis major, it’s also quite effective to massage the entire space underneath the clavicle, using the big knuckles. You might need some oil or lotion for this, of course. Another trick is to trap a small ball between the chest and a wall.

Glide or roll towards the centre, catching Spot No. 9 along the way. Try stretching the muscle at the same time, or at least elongating it a bit.

How does Spot No. 9 in the pectoralis major feel?

This spot feels good because the pectoralis major is partly responsible for the common problem of a collapsed chest, the shoulders rolled forward and inward. Almost everyone feels tight in the chest because of this, particularly people who routinely work or play with computers (which is almost everyone, these days).

Pressure on Spot No. 9 tends to relieve that uncomfortable sense of constriction and stagnancy in the chest, creating a sense of having more space to breathe in, which is quite pleasant.

Bonus pectoralis major tip: strength training

A lot of men would like to have better developed and well-defined pectoralis major muscles for aesthetic reasons, because “huge pecs” are pretty much the definition of a masculine trait. Unfortunately, few men understand which exercises will achieve this effect!

The confusion arises from the fact that the bottom half of the pectoralis major performs some different functions than the top half. To build up the pectoralis major, you need to exercise the bottom half of the muscle. While all pectoralis major fibres adduct and internally rotate the shoulder, only the lower fibres extend the shoulder. Therefore, the best pectoralis major training exercises include some resistance to shoulder extension. Those exercises are:

Note that standard wide-position push ups are a good general pectoralis major exercise, but do not isolate any part of the pectoralis major.

Appendix A: Is trigger point therapy too good to be true?

Trigger point therapy isn’t too good to be true: it’s just ordinary good. It can probably relieve some pain cheaply and safely in many cases. Good bang for buck, and little risk. In the world of pain treatments, that’s a good mix.

But pain is difficult and complex, no treatment is perfect, and there is legitimate controversy about the science of trigger points. Their nature remains somewhat puzzling, and the classic image of a tightly “contracted patch” of muscle tissue may well be wrong. What we do know is that people hurt, and it can often be helped.

The Perfect Spots are based on a decade of my own clinical experience as a massage therapist, and years of extensive science journalism on the topic. Want to know more? This is the tip of the iceberg. I’ve written a whole book about it

Not too good to be true.

Just ordinary good. Trigger point therapy isn’t a miracle cure, but it is a valuable life skill. Practically anyone can benefit at least a little & many will experience significant relief from stubborn aches & pains. The first few sections are free.
