Fascia is the organ of posture. Nobody ever says this; all the talk is about muscles. Yet this is a very important concept, and because this is so important, we as Rolfers must understand both the anatomy and physiology, but especially the anatomy of fascia. The body is a web of fascia. A spiderweb is in a plane; this web is in a sphere. We can trace the lines of that web to get an understanding of how what we see in a body works. For example, why when we work with the superficial fascia, does this change the tone of the fascia as a whole.
