Everyone has Heard of Tai Chi. Since the earliest widespread promotion of the health benefits of Tai Chi, the art has developed a worldwide following of people for its benefit to personal health. It is said that focusing the mind solely on the movements of the body helps to develop a state of mental calm and clarity. Why are people doing it? The physical techniques of tai chi are characterized by the use of leverage through the joints based on coordination and relaxation, rather than muscular tension, in order to neutralize, yield or initiate attacks.
