I was doing the anchoring sacrum exercise and was amazed at the amount of change there was in the length and configuration of my spine. When I first laid down I felt like I was shorter on one side and my alignment was not good at all. During the exercise it was as if my spine just unfurled and the side that was shorter "normalized." I don't see how all that could be from gravity or even how my spine could decompress that much from just laying there. Amazing, just simply amazing.
