Hojo undō

Hojo undō (補助運動) is a Japanese language term, translated as "supplementary exercises", that refers to the conditioning exercises specifically used in martial arts. Hojo undō training was designed to develop ambidextrous physical strength, stamina, muscle coordination, speed, and posture. This style of training uses simple, traditional devices, made from wood and stone.

Weighted items

Chi Ishi

Chi Ishi (weighted levers) are concrete weights that are attached to a wooden pole. The practitioner strongly grips to the end of the wooden pole (opposite the concrete weight), and moves his or her wrist and arms in motions used in techniques normally used in kata or against opponents. This weighted training helps strengthens the fingers, hands, arms, and chest.

Ishi sashi

Ishi sashi are hand-held weights in the shape of padlocks, traditionally made of stone.

Tetsu geta

Tetsu geta (iron clogs) are worn like sandals, but requires gripping the clogs with one's toes. The practitioner then moves around and kicks while wearing these. The extra weight required to move the foot strengthens the leg for kicks.
