Hi, all! I read the chapter on Breathing in a book called “Yoga Anatomy” by Leslie Kaminoff, and found the description of the diaphram to be amazingly informative. So I started “looking” anew at how I breathe, paying attention more to sensations that come from within my rib cage rather than behind my belly skin. (I was told that you breathe into your belly by choir instructors decades ago, and hadn’t questioned it too much.)
I notice that, not only does an exhale end a lot higher than I thought previously, but I have more exhale than I’ve been making use of. In fact, recently and almost instantaneously my energy level has improved when I allow my exhale to continue for as long and to end as high as it wants to.
Have a great day!!!
