Duck

SubFamily

ダッキング(Dakkingu)

Transliteration

Translation: ducking

Overview

The Duck subfamily covers the defensive technique where the fighter rapidly drops their level by bending the knees, lowering the head below the path of an incoming strike. ^[1] The duck is a pure level-change defence — unlike the bob and weave which includes lateral movement, the duck is primarily a vertical drop. ^[1],[2] The duck is effective against high strikes, hooks, and spinning techniques, and it leaves the defender in a low position that can transition directly into takedown entries in MMA. ^[2],[3]

Biomechanical Mechanism

Primary Action — Moving the head off the centre line to avoid an incoming strike without retreating

Joints Involved — Cervical spine (lateral flexion), knees (level change for bob and weave), hips (rotation for counter position)

Force Vector — Lateral or downward — the head moves just enough to make the strike miss while maintaining counter-striking distance

Counter-attack Advantage — Slipping loads the rear hand or lead hook for an immediate counter — defensive movement becomes offensive positioning

Position & Entry

From fighting stance — Move the head laterally (slip) or vertically (bob-and-weave) to make the incoming strike miss by inches

As counter-setup — Slip the punch and immediately counter — the defensive movement loads the counter strike

Training Notes

✓The duck drops your level sharply by bending the knees — your entire body lowers to avoid a head-level strike

✓The duck is faster than a bob and weave but less versatile — it's a straight-down level change without the lateral component

✓Use the duck against wide punches, spinning attacks, and head kicks — any attack that passes over your lowered head

✓After ducking, immediately change levels for a takedown (in MMA) or rise with an uppercut or body shot (in boxing)

✓The duck is the wrestler's defensive entry: duck the punch and shoot for a takedown in one motion

✓Keep your eyes up and your hands ready — the duck should lower your body while maintaining fighting awareness

✓The duck transitions directly into a shot in MMA: the level change for the duck is the same level change for a penetration step

Common Mistakes

!Bending at the waist and putting your head down — duck by bending the KNEES; the head stays up with eyes on the opponent

!Ducking too slowly — the duck must be explosive; a slow duck gets kneed or uppercut

!Staying down after ducking — rise immediately or transition to a shot; lingering low invites knees and uppercuts

!Ducking against straight punches — the duck is for wide/hooking strikes; straight punches follow you down

!Not keeping the hands up while ducking — maintain your guard during the level change

!Ducking without a follow-up plan — counter-attack or shoot immediately after the duck

!Using the duck against a knee striker — ducking into knee range in MMA or Muay Thai is extremely dangerous

Sub-techniques

Standard Duck

Genus

The Standard Duck executes the fundamental ducking defence where the fighter rapidly drops their level by bending deeply at the knees, lowering the entire torso to bring the head below the incoming strike's arc. [1] The movement must be quick and compact — a sharp downward bend of the knees with the back relatively straight to maintain balance and vision of the opponent. [1,2] The standard duck finishes with the fighter in a low, athletic position from which they can fire counter-strikes, shoot for takedowns, or rise back to fighting height. [2,3]
