Tai Chi is a martial art which has gained worldwide popularity due to its many health benefits. The principles of Tai Chi can be applied to many other activities, helping to create fluid, graceful movement. Tai Chi movement is based on 8 techniques which are based on the foundation of the 8 Trigrams. Each of the 8 Trigrams is said to represent a unique movement energy, and it is said that every movement in Tai Chi can be explained using only these 8 energies or techniques. Despite Tai Chi's wide popularity, the mechanics of these techniques has never been fully explained, that is until now. The Tai Chi Code is a first of its kind mechanical analysis of the 8 techniques, explaining exactly how to move the core to create them. In The Tai Chi Code, the mechanics of each technique are explained and then applied to every movement of the Yang Style 40 Movement Form. The Tai Chi Code is one branch of the Quantum Movement System, created by Dr. Todd S Martin, a physician, Tai Chi practitioner, and professional Argentine Tango dancer.
