Hojo Undo
(supplemental Trainng)
Hojo undo, or supplementary training, is the term used in Karate to refer to training with equipment (also known as kigu undo). Since ancient times, Okinawan karateka have been using domestic tools to build up strength, develop impact power, and therefore enhance their martial practice. Using the tools is the key to developing the devastating power of Karate techniques. Miyagi Chojun Sensei stressed that the practice of kata without the correct physical conditioning of the body amounted to nothing more than gymnastics and could not be considered true bujutsu (martial art). By forging the techniques found in the kata, the value of hojo undo training becomes apparent.
"Supplementary exercises, hojo undo, are practiced with the aim of perfecting the kata. The purpose of these exercises is not only to develop strength and power in the body as a whole, but to develop each part of the body individually in order to develop complete body power."-Miyagi Chojun
