Winding up
Pulling the hand back before the loop makes it easy to read.
What Tori does instead: The arc starts from the guard.
Punch lesson 5 of 6 Rear hand
A looping rear-hand punch that rises up, travels over the top of the opponent’s lead hand and comes down onto the head. It’s usually thrown while ducking slightly off the line, so it doubles as a defence.

At a glance
Loops over the top and comes down. Tori stands orthodox, with its left foot and left hand in front. A left-handed (southpaw) fighter mirrors everything on this page.
Think of it as a cross thrown on a curve: the same rear foot and hip drive, but the fist travels over the top instead of straight.
Step by step
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.
Guard. Hands up, eyes on the opponent.
Slip. Tori bends its knees and moves its head a little off the line to its left, as if slipping a jab. The rear hand starts to rise.
Loop. The rear hip turns and the fist travels up and over in an arc with the elbow high, like throwing a ball overarm.
Land. The fist comes down onto the side of Uke’s head, over its shoulder. Tori’s weight is forward over its lead leg and its own head is off the line.
Follow through. The fist carries on down and across as the body finishes turning.
Reset. Tori comes back up into its stance, guard high.
Where the power comes from
A punch isn’t thrown by the arm alone. Each link passes the movement on to the next, from the feet up to the fist.
The dip lowers the body, then the rear foot drives and pivots.
Turn hard, just like the cross.
Falls forward and down behind the punch.
Arcs over with the elbow high, turning the fist over as it drops.
Checkpoints
Freeze Tori on Land and check each of these.
Common mistakes
Robots make these mistakes too, until someone updates their firmware.
Pulling the hand back before the loop makes it easy to read.
What Tori does instead: The arc starts from the guard.
The opponent’s jab or counter lands first.
What Tori does instead: Slip first, punch second.
A miss leaves the puncher off balance and open.
What Tori does instead: Weight over the lead knee, not beyond it.
Swung round the side, it turns into a slow, wide hook.
What Tori does instead: Up and over, then down.
The fist
Tori’s hands have real robot fingers. Watch them in the Close-up camera: the grip is loose in the guard and clenches at the moment of impact.
In a fight (between robots)
Punches are called by number on the pads in many gyms: 1 jab, 2 cross, 3 lead hook, and the uppercuts 5 and 6.
The loop is slow, so distance works well.
Lead glove high, shoulder up.
Duck under the loop.
Move to the side the punch comes from, inside the arc.
This page explains how the overhand 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. Don’t hit anyone. If you want to learn to box for real, learn in person from a qualified coach and check with a doctor first.
