Hojo Undo – Exercises & Equipment

List of Hojo Undo Exercises & Equipment

Hojo Undo are strength training & conditioning exercises used in some Japanese & Okinawan martial arts, especially by more traditional Karate schools. Hojo Undo is also known as “Supplementary Exercises” or “Supplementary Training”. Hojo Undo exercises use specialized equipment such as stone hand weights and gripping jars.

Hojo Undo exercises are used to improve kicking powerpunching powerspeed, coordination, etc. Unlike traditional weight lifting, most Hojo Undo exercises do not focus on a single muscle group (i.e. lifting dumbbells to increase your biceps). Instead, many of Hojo Undo exercises (i.e. the swinging of Chi Ishi) are designed to enhance the natural body movements used in martial arts training. For example, some Hoju Undo exercises work on strengthening the motion and muscles used in a punch. This type of training is similar to modern “functional” strength routines such as medicine ball workouts and kettlebell workouts.

All stretches and exercises should be supervised by a trained martial arts instructor in order to prevent injuries and to ensure the proper technique is utilized. If you have had an injury or are in pain, please see a doctor before starting any stretching or exercise program. For additional stretches and exercises, please visit the main Martial Arts Physical Fitness section.
