Following the success of his Guide de la foulée (Stride Guide, 2016), which sold about 10,000 copies, Frédéric Brigaud explains in this new work how to act on one’s posture, correct joint instability and rebalance one’s body to forestall non-traumatic injuries of the osteo-articular system. A video is available with exercises on the publisher’s Youtube page. Frédéric Brigaud is a certified osteopath and a consultant in human biomechanics; he developed the posture-dynamic and biomechanical approach of the body in movement (EAD, Empilement Articulaire Dynamique©), for individuals as well as high-level athletes. His works have been translated into several languages, including Korean, Spanish and Italian.
