Great book for anyone interested in somatics, biomechanics, Feldenkrais, running, Taiji quan (Tai chi), walking, moving or in pretty much everything you do in life. The book is like sending a message, let's talk effortlessly about effortless movements, let's talk about how to slow down a bit to speed up a bit. The second part is also nice with many Feldenkrais exercises. One those books that you get back to re-reminding yourself a bit on your moving habits. No matter if you are a recreational or professional athlete, passionate walker or you simply enjoy reading on human movements. Improving our comprehension on how human beings are using their bodies and the space is fascinating.
