Kick lesson 5 of 5 Brown belt Rear leg

Spinning hook kick

The showpiece. Tori spins backwards on its front foot, lets the leg rise out to the side as it turns, sweeps the back of its heel across Uke’s head guard and keeps turning until it faces Uke again. A full circle in about a second.

    At a glance

    What the spinning hook kick is

    Also called Ushiro mawashi geri Dwi huryeo chagi. Tori stands orthodox, with its left foot in front, and kicks with its rear (right) leg. A left-handed (southpaw) fighter mirrors everything on this page.

    The spin powers this kick and the leg goes along for the ride: the head turns first, then the shoulders, then the hips, and the leg is swung round last.

    Step by step

    What Tori does, frame by frame

    These are the same steps as the buttons under the 3D view. Freeze Tori on any of them, then turn the camera to look from every side.

    1. Guard. Fists up. Uke starts to look worried.

    2. Spin. Tori turns backwards on its front foot, head and shoulders first, keeping one camera on Uke over its shoulder.

    3. Extend. The leg rises out to the side as the spin keeps going.

    4. Hook. The back of the heel sweeps across the side of Uke’s head guard.

    5. Follow through. The leg keeps travelling round with the spin.

    6. Land. The foot comes down and Tori faces Uke again, a full turn later.

    Diagram seen from above: the path of Tori’s kicking foot in the spinning hook kick, from Tori on the left to Uke on the right. TORI UKE way inway backleg risescontact
    Seen from above: Tori turns a full circle and the heel sweeps a wide arc across the target (solid line), then carries on round and down (dashed). The roundhouse curves in from the front; this one comes round from behind.

    Watch it like a coach

    • Camera Top at ¼×: the whole circle, and where on it the heel meets the target.
    • Freeze on Spin: the head has turned before the leg leaves the mat.
    • Camera Behind Tori at ½×: the leg straightening as it swings in.

    Where the power comes from

    From the floor to the foot

    A kick isn’t thrown by the leg alone. Each link passes the movement on to the next, from the standing foot to the striking one.

    1. Head and eyes

      Turn first, to find the target over the shoulder.

    2. Shoulders

      Lead the spin.

    3. Hips

      Follow and swing the leg up and round.

    4. Heel

      Sweeps across the target and keeps going.

    Checkpoints

    What to look for in the demo

    Freeze Tori on Hook and check each of these.

    • Eyes on Uke The head is already round.
    • Back of the heel Not the calf and not the toes.
    • Leg nearly straight It swings in long and hooks at the end.
    • On the ball of the foot The standing heel is off the mat.
    • Follow through The spin doesn’t stop at the target.
    • Guard up The hands stay near the face during the spin.

    Common mistakes

    How the spinning hook kick goes wrong

    Robots make these mistakes too, until someone updates their firmware.

    Spinning blind

    The leg goes first and the head turns late, so the kick flies anywhere.

    What Tori does instead: Head first, then shoulders, then the leg.

    Braking at the target

    Stopping the spin at the target throws Tori off balance.

    What Tori does instead: Follow through and finish the turn.

    Too close

    The calf or the knee arrives instead of the heel.

    What Tori does instead: Start from further away.

    Flat-footed spin

    Turning on a flat foot is slow and grinds the joints.

    What Tori does instead: Spin on the ball of the foot.

    In a fight (between robots)

    How it’s used, and how it’s stopped

    Kicks rarely come alone. They are mixed with punches and with other kicks, so each one sets up the next.

    Combinations

    • 1-spin

      The jab covers the start of the spin.

    • Round-spin

      A missed roundhouse carries the hips round; the spin goes with it.

    • Back or hook

      The same spin can finish as a back kick or as this hook.

    • Low-high

      A low kick brings the guard down, then the heel sweeps high.

    How Uke could stop it

    • Duck

      Drop under it. Uke does this when it dodges one.

    • Step back

      Out of the circle.

    • Jam

      Step in before the leg gets going.

    • Cover

      The arm comes up to the side of the head.

    A robot demo, not a class

    This page explains how the spinning hook kick works so the animation makes sense. It isn’t a martial arts course, and it isn’t self-defense, fitness, medical or safety advice. Tori’s version is simplified and exaggerated for the camera, and robot joints bend in ways yours shouldn’t. Don’t kick anyone. If you want to learn a martial art for real, learn in person from a qualified instructor and check with a doctor first.
