About Yuan Yen Do Karate Centers

Our System

Yuan Yen Do Karate Centers

Yuan Yen Do, which when translated from the Chinese means “The Way of Change,” is based on the premise “Learn the Moves within the Moves – the Transition.” Yuan Yen Do seamlessly combines the hard style of Karate and the soft style of Kung Fu, with the emphasis on the extremes of the two. The results vastly improve delivery speed and power by allowing the sequentially arranged moves to progress without transitional lapses, one move feeding the next in a chain reaction where the whole becomes greater than the sum of its parts.

About us

Yuan Yen Do is a Martial Art that is designed to be both a defensive and offensive fighting system with multiple combinations of Blocks, Strikes, Kicks, Fakes, Feints, Checks, Deflections, Evasions, Grappling, Sweeps, Reaps, Leg Hauks, Throws, Ground Fighting and Multiple Attack Scenarios. Through the study of the Internal Systems of Tai Chi, Chi Kung and the Six Animals – Tiger, Leopard, Crane, Snake, Dragon and Monkey – each member learns to remove the “and” from Block “and” Strike, eliminating the transitions between the moves. As the Curriculum and Body Mechanics are refined, a higher level of Mind State is developed, empowering each member to effectively handle ANY opponent, regardless of age, size or strength.
