Striking surface

Primary: fleshy area above the kneecap.
Avoid unintended contact with the side of the knee, shin or foot.

Basic principles

Hiza is a close-range weapon. Keep the body compact and transfer force through the supporting leg, hips and trunk into the knee.

Execution and use

Drive the knee upward or forward on a short path, use the hip to carry the motion and recover balance immediately. It appears in close-range and kumite situations.

Training

Use kihon, controlled close-range exercises and kumite drills. Focus on the correct knee zone, downward toes, strong hip action and stable balance.

Common errors

• wrong contact area
• toes not pointing down
• poor hip balance
• movement that is too large for close range

Summary

Hiza (膝) uses the knee as a compact close-range striking surface supported by strong hip action and balance.
