I love this video! It’s always great to see Kstarr and Jill collaborate and connect their respective followers to one another. Two most eye opening things I got out of this post were: 1 – The diaphragm attaches to the lower 6 ribs … this is the skirt steak! (put’s it into perspective!) 2 – The tails of the diaphragm cross the psoas and string onto the lumbar spine 3 – #2 means that there’s a shared relationship between the diaphragm, the QL and Psoas 4 – You may have trouble with recovery and calming down if your diaphragm is… Read more »


Great action with the ball – very similar to a stretch in FST called the rhomboid roll. Looking forward to utilizing it to help my thoracic spine! Thanks.

Thanks for the video! I just wrote an essay on the diaphragm and coupled with this video and the other research I have done- I have a knew awareness as a teacher that I want to share with my students to support healthy diaphragm function. I find myself pausing throughout the day to perform mindful breathing techniques to exercise my own diaphragm. Thanks!

Great video to help deepen the awareness of the importance of freeing up the spine to more the diaphram. The diaphram allows deep breathing, mental relaxation and is supported by a healthy spine! Important stuff!


Great video which if paying attention covers a bunch of important notes- namely to free up a compressed rib cage in order to allow the diaphragm to be FREE to move 3-dimensionally. I cringe when I hear people saying that chest breath is not diaphragmatic and that belly breath is. I really appreciate that Jill and Kelly are so anatomically aware as to help steer the convo in the direction that we are looking for a freed up diaphragm – not one that is locked into a pattern of habitual tension.


Love this:”incorporating their understanding of biomechanics and anatomy into this ancient technology” of yoga. I second the motion:
Good video showing the relationship of a healthy, supple diaphragm and how it relates to our breathing. Going to try my YTU therapy massage the spinal tissues. Thank you very much..


Breathing improperly through the diaphragm when taking certain positions had not caused me too much aggravation when I was a younger athlete. However, now that I am older, I constantly find my back tightening throughout the day whether working out or not. The ball exercises Jill suggests are quite helpful at targeting hard to reach areas with as much pressure as needed. I didn’t even realize how tight I was in some areas until trying the ball exercise. In addition, I have found that prior to meditation, this is a great way to loosen up and relax the spine.


Diaphragm and Psoas control. The ability to release and contract these two muscle (or this one big muscle) with as much control as I would my arms, fingers, toes, legs, etc. Wouldn’t that be great?

Any information that help educate “the masses” understand the profound link between the breath and performance, and help them develop the actual skill to enjoy the benefits of breathing “better” is huge.

Starrett and Miller. A sweet combination.

Thanks for sharing. I learned a lot today.

Hey there I am so delighted I found your blog, I really found you by mistake, while I was researching on Bing for something else, Nonetheless I am here now and would just like to say kudos for a tremendous post and a all round enjoyable blog (I also love the theme/design), I don’t have time to browse it all at the minute but I have bookmarked it and also added your RSS feeds, so when I have time I will be back to read more, Please do keep up the excellent work.

I love seeing the relationship of the diaphragm to the mighty psoas and to spinal rotation. Though the sound quality is a little poor (hard to hear in places), this video was fun to watch. I will use Jill’s YTU therapy ball exercise to massage the tissue of the spinal muscles behind the diaphragm. Thanks.

Great short video explaining the importance of a healthy, supple diaphragm and it’s impact on breathing. I like the fact that you pointed out the connection with the nervous system. The diaphragm is controlled both by the unconscious (autonomic) and conscious (somatic) mind and therefor provides a unique key for bringing the body and mind together. Great technique for releasing the diaphragm with the YTU therapy balls – thanks.


This video needs to go viral! It has the potential help so many people. Even though yoga is 2000+ years old it is only fairly recently that Jill and other teachers of her ilk are incorporating their understanding of biomechanics and anatomy into this ancient technology. Thank goodness for that and Yoga Tune Up!


This was an interesting video because I don’t think many people realize they don’t breath full “diaphragmatic breathes.” Since asthma, low back pain, and stress are all so common, I think this exercise could be helpful to athletes and office workers alike. Before Yoga Tune Up, I only thought about my lungs when I breath. Now I realize that muscles, especially the diaphragm, support breathing. I think it is amazing that you can roll on these balls, tug at your ribs, and it will help you breath into your thoracic spine!
