A student in one of my Yoga Tune Up® therapy ball classes pulled me aside after class recently to ask about nagging tightness that she was having at the front of her shoulder. Knowing her as a student, I am aware that she is both working on her PhD dissertation and is regularly powerlifting. Whoa. Between the keyboard and the barbell, that’s a whole lotta internal rotation of the shoulder! It’s no wonder she was pointing, with a grimace I might add, directly at her pec minor. Looking even casually at her shoulder girdle it was apparent that her shoulders appeared rounded forward from the pec minor pulling the scapula forward into protraction, and downwardly rotated towards the front of her chest. Even the inferior angle of her scapula was sticking out noticeably.

Her main complaint, along with the Pectoralis Minor pain and tightness, was that she felt she had “slumped” posture from sitting at her computer for so long. She tried to resolve this by shoving her mid thoracic spine forward towards her sternum, in a mock exaggeration of “perfect” 1950’s military posture. Not only does this flatten the mid thoracic curve (which is designed to support our spines in a way to keep strain out of our neck and shoulders), but it also does nothing to address her shoulder placement. While her shoulders may feel farther back because of the distortion she’s created with her spine, those little pec minors are, in fact, still shortened and giving her the appearance of slumped shoulders. All she’s doing is layering overworked paraspinal muscles on top of it all!

So what’s a brainy powerlifter to do? I suggested that she use her Yoga Tune Up® therapy balls to roll out that tight pec minor tissue for YTU therapy ball pain relief (as I demonstrate in the video below). Because of her tendency to to flatten her mid thoracic curve, I also cued her to be aware not to thrust her spine forward, as an Olympic gymnast might,  as she raises her arms behind her, but instead to work to maintain neutral in her spinal alignment.

This was a very effective technique for me, and simple as well! I try to stretch my pecs every day or two, but this allowed me to have greater progress and really unlocked the external rotation that was missing in my shoulder.

Lucy Beiler

What a great reminder for me to release the pec minor as I catch myself in a slumped posture at the computer, doing dishes or when I feel discouraged. All the ‘minor’ muscles are a rather major deal. Thanks for sharing.


Pec Minor sometimes is forgotten and most people don’t realize it attaches to the scapula. This post is great to share for those people who are lifters and also work in a flexed position. I know a ton of them and can’t wait to share this. The block is a great idea to get into that deep area.

This little muscle is often like invisible, we didin’t feel it work, buy when he’s wake, after exercise, we feel it for sure! I will try this rolling next time!

Isabelle Deschenes

Thanks! As a lifter and a desk worker, this made me realise that it will be a got thing to lift with an external engagement. Im gonna try this!


Very intelligent to be aware of the thoracic spine’s potential to compensate for poor scapular control! This is often the case with lifters in general; flat T-spines are very common. I’d be willing to bet her Lats are playing a big role in this as well, even just synergistically. The lats can also pull the scapula into an anteriorly tilted position indirectly by pulling on the humerus. As well, the lats have a tendency to overextend the spine is not used properly. Food for thought!

Nick Shrewsbury

Brooke, that’s really helpful for finding the pec minor with the roll model ball- and developing awareness about the activities that cause tension and adhesions in that muscle. Thanks!

Karen Bulmer

Thanks for this post and super helpful video tutorial. I have been pec minor obsessed for the past few months. I work with musicians, many of whom can’t get enough air in part due to the lack of mobility created by super tight pec minors! I am going to try this exercise with them.


Just wanted to say thank you. I’ve had an issue with my thumb, index and forearm going numb when my hands are in my lap during meditation. I’ve tried every other trigger point on the back and shoulder I could think of but this has brought some relief.

Lita Remsen

I often do pec releases on the Fall so it is good to be reminded to do it on the wall. I also find it helpful to do upper traps / levator scapulae releasee against the wall.

Kathy Shaul

This is hands down one of my favorite YTU ball exercises to do and share! Anyone that texts or uses a mouse all day will feel immediate relief. I find the alph ball great for this area too!

Tracey Arnold

Now I finally understand why my shoulders blades pop out! Teachers bring it to my attention but haven’t explained why or what I might do about it. Thanks so much Brooke for teaching me. For now on, they’re going to get rolled!


I am a massage therapist and teach yoga at a crossfit…and the poor pec minor is often as you said “a major pain” with my clients. Often novice lifters are lifting weight that may be too heavy for them and pulls their shoulders into depression and protraction, precisely the pec minors job. I advise them to lift lighter until they can do the weight with their scapula retracted, but in the meantime, the therapy balls have given much relief. Thanks for your article, happy to see one for lifters.

Delfina Bonilla-Lopez

Oh pectoralis minor! How you have haunted me for so long. I sometimes jokingly call the pec major and minor the ape-muscles because they can create so much scapular internal rotation that it can make you look like you’re walking around a bit like an ape or a gorilla. Moving on. I love this short roll sequence because it can make such a huge amount of difference in such a short amount of time. And, I love the guitar string description. I couldn’t have described what that might feel like when you roll on it any more perfectly. I’ve totally… Read more »

Ali Bell

Thanks Brooke. Another great reason to take my balls to the office with me – long hours working at a computer interrupted by pec minor roll outs.

Elizabeth Bond

I love this rolling technique. As a massage therapist that spends a lot of time in internal rotation this is is an everyday must for me. I had been doing a similar technique in a door jam, but the block against the wall made all the difference!

Emily Pantalone

This is my favorite YTU therapy ball routine to do. I have chronic tightness in the front of my shoulders from years of slouching and studying too hard. I remember that it blew my mind when I first realized that should and upper back pain could be a result of tightness in the FRONT of the chest. Ever since, I never massage or roll out my shoulders without also relieving the front of my body.


Very informative..I have the same issues with my pec minor due to being a massage therapist and a student that spends a lot of time on the computer typing.

Alison Pignolet

It’s such a revelation to students that this little bit of rolling on the front can make such a change to the shoulder. I like the way you hold your 3 fingers to show the muscle location – it looks like a boyscout cross your heart salute! such an easy way to remember how to demonstrate the muscle 🙂 And even after your quick demo your left shoulder looked different before and after.

Praveena Chinthaluri

Brooke, this is really nice. Thank you. I love the internal rotation of the arm while rolling the pec minor, it gets in quite deep into the muscle. A quick fix for the tablet posture. A must share with my students:-)


I am totally guilty of being on my laptop a lot as well, and I do have a more internally rotated right shoulder. Ever since I’ve been using the therapy balls I am able to see the amazing relief my pec minor has received. When I lay on my back now im able to not see a crease on my shirt due to shoulder internal rotation.

Thank you for the great advice!


I like adding the arm rotation! I have the same issue from overhead pressing the barbell & bench pressing. In my class the instructor had us using an Alpha Ball & I was sold on the therapy balls ever since!


Thank you! Reminds me to balance out my front body as much as the back


Very nice- thanks for sharing! I’ve done this release on the floor, but it’s very awkward/difficult for some clients that way. Standing upright is much better for some, and you can till get a good amount of pressure for that pesky pec!

Jill D

Thanks for the info Brooke! I’ve learned to pay much more attention to my pec minor and this is one of my absolute favorite areas to use the therapy balls. I partake in all those modern daily activities that lead to an over indulgence of internal rotation, so I try to be diligent about counteracting the action and using the therapy balls daily. I always receive an immediate response when using the therapy balls on the pec minor – when checking in after one side I can visually see a difference. I also feel more ease in my breath, more… Read more »


I love this one. I DO have a job where I spend the better part of every day typing, shoulders eventually drooping forward. I can almost feel pec minor squeezing shorter! :-(. This feels wonderful at any point during the day, and really helps restore posture, movement, freedom of breath, and lots of other good stuff! Thank you, Brooke!


Wonderful information – I have this same issue after working at the computer.

Alex Booth

I found this article very interesting as an ex powerlifter who suffered from shoulder issues. A lot of popular programming promotes high volume pressing which if not balanced out with tons of pulling work will cause all that internal rotation. I’ve personally used some of the techniques you described with great success. I don’t think I’d be able to do any pressing today if it weren’t for the soft tissue work and mobility I’ve done on my pecs and shoulders. An Ideal powerlifting bench arch really works to protect your shoulders preventing your elbows from going too far below your… Read more »


Well done, I find this one works really well for me. I also recommend trying the alpha ball, while laying on the floor, rotate from internal rotation to external rotation full flexion and watch the ball strum it’s way into action as well. For those looking for some additional sheer, don’t forget to pin and spin the superficial fascia.

Amanda Zerbini

Yes, this information and technique feels like the missing link to my shoulder issue. I followed along with the video on the ball massage technique and it already has helped. I’ll be adding that trigger point to my regular routine. Thanks!

Jenny Buchanan

Hi Brooke, This is an excellent video and helps me find just where my pec minor is. I also appreciate the demo on the block as two students I have are so rounded forward in the shoulders that I don’t think they could maneuver working on Pec Minor on the floor. Thank you!

Nicolette David

What I took from this article is how powerful a skill it is to really KNOW your students–what they do for movement or even what they do for work/study. Having this little background info really allows you to tailor both therapy ball work and YTU poses for them. I also happen to Looooove this particular ball technique. Just inspired my class for tmrw. Perfect!


This is one of my faves. I feel like everywhere I look I see excessive internal rotation at the shoulder joint. Including when I look in the mirror. I find this to move to be incredibly helpful to target those small but domineering pec minors. I love that you suggest placing the arm behind the back to allow the muscle to slacken a bit before massaging it with the balls.


Another great video. I love the tip about internal rotation of the arm to access the pec minor with the therapy balls. My shoulders are constantly internally rotated when behind the computer. It’s nice to get some relief.

Stephanie Fish

Great video – clear content and relaxed demo. Funny how lots of times when people “roll out” they “tense up” at the same time. I find a lot of the ball work is great to do at the wall as you showed so people can more easily find structures and stay relaxed and exploratory while rolling out. And I agree the pec minor is such a valuable structure to address to help folks out of the all-too-common schlump.


Brooke, thanks for sharing these great tips and demo. The YTU balls can “get in there” like modality I know of as of print. The relief is almost immediate after the drill. Thanks.

Lisa Cassidy

Wow, that description could have been about me minus the (powerlifting and PhD haha!) I have shoulder tightness from a guarding and positional comfort when I had a c-spine injury a couple of years ago that made my right arm go numb and shooting pain down my arm. I could not do much with my arm, other than keep it cradled in one position like it was in a sling. As I started to heal, I had no strength in my right arm and did a lot of compensating. This has created an internal rotation and makes my scapula stick… Read more »

Allison Shapiro

So amazing what just a few minutes with the therapy balls does. I thought all my tension was in my trapezius but NOOOO…lo and behold there IS tightness in my pecs too. The video was very helpful as were the YTU poses suggestions for helping with this tiny but significant muscle. Thanks!

Renee holden

Brooke, great article! We see far too many people with postural issues that can be corrected quite easily with specific Tune up ball exercises targeting the pec minor, with only minutes a day of rolling.small changes can make big differences , especially in the workplace with an ergonomically correct desk set up, and the knowledge of how to release the anterior muscles to bring that thoracic spine into better alignment. It will be interesting to see our society in 20 years, as our children now are doing for hours what we have done now as adults for only a couple… Read more »


Thank u! I had a fall 10 years ago on my right shoulder. I Injured it enough to get an X-ray …and then on down the road a cortisone shot. Over the years I have been careful with…not realizing that was not the best medicine. A few years ago I started to really play with the ROM and saw it was capable, but fearful. YTU balls have almost brought me back to a healthy range of motion. Hoo- ra!

Michelle Dalbec

Brooke – This is a great article and video, THANKS! The feedback that I get from the outside world is that other admire my posture. Until recently I thought I had optimal posture and while I’m close, I’ve come to realize how unbalance my shoulders are. Through lots of looking/feeling deep within during many practice I have become aware of two major imbalances: that the muscles of my chest are very tight, pulling the shoulder forward which is resulting in the muscles of my upper back (serratus posterior superior and rhomboids) doing overtime work to deal with my shoulder placement.… Read more »

brooke thomas

Hey Giancarla thanks for the great question! In my opinion, we should work our tissue (via therapy ball work like this or of course other YTU work to organize the shoulder girdle) so that our shoulders don’t have to do anything in pedestrian life! If you look at a skeleton, you’ll see that the bony architecture of our shoulders is designed to just sit there, like glorious shoulder pads. The clavicle into the scapula allows for the arms to just hang naturally, without any efforting. Now the rest of us have a good deal more living soft tissue than the… Read more »


I need to do this like ten times a day every day of my life! Even as I am sitting at a computer right now, I cannot help but feel the tightness in the anterior of my body and with my arms straining and clenched as they are protracted forward towards the keyboard. In your opinion, what would the arms want to practice doing in pedestrian life? I would assume the opposite of the internal rotation… which is external rotation, would you also depress and adduct the shoulder actively or keep it separate? Other than rolling out the pectoralis minor… Read more »


Just learned this YTU Ball exercise today in training – and establishing that balance from front to back makes so much sense for so many of us these days – especially with the technologies that put so many in a forward ergnomically incorrect position. I liked the reminder of how many people will try to overcorrect with the forceful extension of the thoracic spine – Thanks!


Thanks Brooke, great tip! I have several students (myself included) that need work to stretch through the pec minor and balance support tension through the shoulder girdle in general. More often than not, they’re weight lifters and/or on the computer a good deal. This Therapy Ball stretch will be a great addition that I can pass along!

Lauren Goodwin

LOVE.THIS.EXERCISE. Luckily I don’t have a job where I have to sit at desk typing away at a computer everyday all day long, but there are a day or so a week where I do unfortunately have to do so. No matter how hard I try to maintain correct and proper posture, I always leave the desk with tightness and discomfort in my pec minor area that I just couldn’t seem to shake. Once I started doing this exercise after I would finish my “office work” I felt so much better- no ore discomfort and I didn’t feel like I… Read more »
