Hojo Undo translates as “supplementary exercises”. It is the study and practice of the ancient Kigu (equipment) used in Okinawan Goju-Ryu Karate-Do. Most of the Hojo Undo equipment, with the exception of the Okinawan Makiwara and the Kongo Ken, were brought to Okinawa by Master Kanyro Higaonna upon his return from Foochow, China. Hojo Undo strengthens and toughens the body, develops Qigong (practice of internal and external universal energy) and Kokyu-Ho (inhale/exhale breathing method). Ancient implements of Hojo Undo are Makiwara (striking post), Chiishi (stone lever weight), Nigiri Game (gripping jars), Ishi Sashi (stone padlocks), Tan (Chinese barbell), Tetsuarei (dumbbells), Kongo Ken (oval metal weight), Sashi Ishi (heavy stone), Tou (bamboo bundle), Tetsuwa (iron rings) and Makiagi Kigu (wrist roller).
