Superheroes usually have well developed pec major/minor mucle groups!
The pectoralis minor is such a little guy. He’s ignored, not understood, and often fed up. He’s not going to take it anymore. He’s tight with resentment. He needs attention, and he’s not going to let you forget how you ignored him for so many years.
One of his major functions is to help elevate your ribs during inhalation – particularly during aerobic exercise. Oxygen, anyone? Is anyone listening to this little guy?
Here’s 1) why I think YOU should be paying attention to your pec minor and 2) what you should be doing to take care of him. He will love you for it!
This post is geared to those of you out there who spend a lot of time during the day sitting at your desk or in jobs that require a lot of sitting. Particularly, for those feeling twangs of pain in your neck and shoulders that you haven’t been able to figure out how to fix.
Here’s the thing: when you sit most of the day with your arms out in front of you, you’re putting a lot of stress on the front quadrant of your body. Read this for more about exciting ergonomics tips. Gravity alone will compress those anterior (in the front) muscles, it is important get control of the situation early on.
Take a break and stretch, OK? Agreed?? (There’s a video at the end of this post as well as another great stretch at my previous post).
Understand where it is and how it’s connected…

Look at the image of the pec minor. See how it originates at the 3rd, 4th, and 5th ribs and inserts into the coraoid process of the scapula? Yeah, that’s right, it bridges the ribs to the inside tip (anterior) of your upper scapula, that blade-lookin’ bone in your back.
When the pec minor becomes shortened, contracted, or “tight” over time, it becomes harder to take a full, deep breath. As that pec minor shortens and becomes restricted, you’re taking shallower and shallower breaths. Not good.
Plus, as this muscle tightens, it can make you “think” pain is emanating from your trapezius (upper shoulders) or neck. But that’s why he’s so tricky! Your upper back hurts because those little pissed off guys (and other associated muscles like the serratus anerior) are pulling your shoulders and upper back down towards your lap, and now the shoulders/traps and scalenes (scalenes are in your neck) are getting angry. That group of muscles must do extra work to keep you upright, to keep your lungs from being trapped by the angry pec minor.
One big happy family…
Yeah, and all this time you thought the body was supposed to be a harmonious partnership, a big happy family of organs, muscles, bones, and connective tissue helping each other out. Well, I hate to break this to you, but if you neglect one guy over the other, the neglected dude will get even with you. Mark my words. (And I’m gender neutral, just happened to be calling body parts “he” today, forgive me guys—no offense.)
Support those arms, take a break and stretch, move around at least once an hour, stop slouching, get those shoulders back to neutral position, make the door stretch a habit. The more you neglect these little guys, the more lung capacity you loose, the more tired you feel, the more your shoulders and neck will start aching. Better yet, start a weight regime. (I know, I know, I am bored by the gym, too, but I make myself strength train anyway!) If you’re not sure what exercises to do, email me (contact info here).
I’m adding a video below to show you an alternate stretch you can do at home for both the pec minor and major (and no, that’s not me). I manage to incorporate this stretch at least a few times a day.
You only have one fortress—take care of the foundation, ropes, and bridges, and they will take care of you, too!
Create your day!


Ah, does this explain why my neck, shoulders and upper back get achy since I’ve taken up knitting?
Thanks, Lori!

Well, Gayze, it can be complicated regarding what could be causing your neck, shoulders, and upper back to ache. This post is about just one of the many possible causes.
That said, the pec minor is a good place to start. In general, the achy feeling you’re speaking of can be attributed to not moving around enough – staying in the same spot for too long. Try to vary your position and take a lot of breaks! Are your arms resting on a stable surface? Is your neck in a neutral position or are you looking straight down for extended period of time?
Also, congrats regarding your first scarf!
Good morning!
I do stretch often, at least whenever I think of it, and tried a modified (as in: “If I get down on the floor I’ll never get back up again” ) version of your stretch last evening, and it did seem to ease some of the strain. I’m sort of “stuck in one spot” due to my health situation, so the only think my arms are resting on when my knit is my belly.
I’m working on healthier modification ideas, thanks! (I’m also working on “less belly”, LOL)
And thanks for the congrats on the scarf, too!

Is that why, after you’ve been sitting hunched over your work for several hours, that it feels so good to lean back in your chair, stretch your arms out wide, and stretch as far as you can? It always seems to help you breathe easier afterward, and you feel more refreshed.
Thanks for introducing us to another great muscle, Lori!

You got it!! You’re right on the money!
Hey, Jay, thanks for reading this stuff. When I learned all these little tips and tricks in school, I was amazed at all the shenanigans muscles can pull on us (pun intended) – tricking us that pain is coming from a different source. Don’t be fooled, and, YES, keep stretching! Sooooo good!
Thanks for reading along. And, as always, thanks for stopping by!
Can you do a post on the rotator cuff which is the cause of shoulder pain? Thanks, Lori.

I’ve penciled in it, Gordie! You got it.
Have a great day!
Hi Lori,
I really like the looks of this stretch! In fact, I just felt myself sit up a bit straighter (that’s a good thing!). Good stuff!

Hi Lance,

Great! It’s a simple little stretch, but it goes a long way to helping us to feel better.
Keep on keeping on, Lance.
Enjoy your day!

Nice post…As someone who has had shoulder/neck problems for a long time, I know I need to pay attention to this more. It is amazing how all of our muscles are connected. I love the picture, as well. Thanks for sharing this!

Hi Tim,
I’m glad you loved the photo of the pec minor. I like that one, too. Beautiful, isn’t it?
I hope that this short post about this muscle (and the mayhem it can cause) can help relieve some of your shoulder/neck problems. If you have further questions or comments, please let me know via email if you’d like
Great to see you again.
This post was written for me; sore neck, tight traps and pissed off little pec minors!
It was too funny, as I was reading, even before I got to the part about not slouching, I pulled my shoulders back and sat up straighter!
OK, gonna give my pec minors some lovin and go stretch! Thanks Dr Lori, “Spokesperson and Supporter of all that is Muscular”!

Hi Sami,
Oh my, it has been a long time since someone has addressed me as Dr.! Just to clarify – I am not a doctor that treats patients. Give me your DNA, though, and all bets are off!
Hey, great, Sami! If I can get just one person to be aware of the stress he or she is putting on those poor little guys, I’ll feel my work here has been worthwhile. Thank you!
Enjoy your evening in the mothership, and I’ll see you tomorrow, Sami! ~xo
I was recently talking to an elderly osteopath. He said “most old people that you see all hunched over aren’t just old–they’re weak.” He recommended hip flexor stretched and a couple of shoulder stretches as “the fountain of youth.”
That hunched over look comes from the psoas dragging you down, and your shoulder round, and then all you can do is shuffle.
A couple of easy things that you can do every day and get benefits from for decades.

And there you go – that’s it! I should have mentioned this in my iliopsoas post, but you’re right on!
Thanks for contributing to the conversation, Josh. You rock!
Hi Lori,
Thank you so much for this information. Now I know why I feel the way that I feel when I am at work (besides the fact that I am surrounded with a bunch of cranky pants).
I will definitely do that exercise too. Very cool. Thank you for teaching me something new. It is much appreciated.
You rock!

Hi Nadia,
You spurred me to laugh already this morning! Cranky pants…ha ha ha! That can definitely do it, Nadia, all those cranky pants. I hope you can get outta there soon!
Thanks for reading, I always feel like I’m stuffing muscles down readers’ throats, but I really believe if everyone knew the secrets that their musculature holds – and wants to whisper to us- life would be such a better (and more comfortable!) place.
You’re the best, I love having you here. ~xo
