A hook kick (also called a Hooking Kick, 후려차기 or huryeo chagi) is a kick that strikes the target with a hooking motion.
The hook kick strikes with the heel of the foot (or with the flat of the foot in sparring), from the side of the target .
- The (Front) Hook Kick is initiated similar to a Side Kick: the kicking knee is raised to point at the target, then the off-foot pivots to the side, so that the hip of the kicking leg turns over. For a Hook Kick however, the kick is intentionally aimed slightly past the target in the direction of the kicking foot's toes.
- The leg is then extended to the side of the target, so that the target may be struck with the heel. At full extension, the knee is then bent and the foot snapped to the side, impacting the target with the heel.
Normally the striking surface is the back of the heel of the foot, but at closer range the back of the calf or the back of the bent-knee can also serve as the striking surface.
The most common variation of the Hook Kick is the more powerful Back Hook Kick. There are many other variations of the hook kick as well, generally based on different footworks: rear- or front-leg, oblique or half-pivot, dropping, spin-back and more. The hook kick can be delivered with a near-straight leg at impact, or with a hooked finish where the leg bends before impact to catch the target from behind. An important variation is the downward hook kick, delivered as a regular or a spin-back kick, in which the end of the trajectory is diagonally downwards for a surprise effect or following an evading opponent.
