In this Video I explain how to relieve low back discomfort with Yoga Tune Up therapy balls and your breath.
My suggestions for following this video are to give yourself a moment to breathe fully, smoothly and completely. Find a place to do this where you can introvert your attention to what you are feeling. Even if you are in a noisy gym, simply close your eyes and teach yourself that you can learn to be calm even in the most challenging places.
It's helpful also to think of your body as your feeling/sensation brain that is just as smart as your thinking brain and speak directly to that part of you where you hurt. Literally take a moment and ask it what it needs. You will be very surprised at the answers.
