The second edition of Fascia: What It Is and Why It Matters, the first being the "must-have" book for everyone wanting to learn more about fascia as a tissue and a system, maintains the high standard of the first book while expanding on everything that made it so popular. By focusing first on the fundamentals of fascia as a tissue that surrounds, supports, and permeates all the muscle, bones, nerves, and organs, Lesondak takes the reader on a journey throughout their entire body from the perspective of the fascial system, making many stops along the way to make sure the reader understands what it is that's important and why it matters to the body. Following the new rules of biomechanics, biotensegrity, cellular processes, musculoskeletal issues, proprioception, neuroscience and cognition, somatic dysfunction, and restoration - Lesondak deftly weaves it all together with a deep appreciation for the history of science, fine storytelling sensibilities, and a sense of humor as well as a sense of wonder.
