The Rolling Kimura is a dynamic Kimura Trap bottom technique where a figure-four grip on the opponent’s arm powers a roll-through that simultaneously threatens the shoulder lock and sweeps you up into back control or top kimura trap.
Rooted in the Kimura Trap bottom system, the Rolling Kimura turns a defensive-looking bottom position into a launching pad for sweeps and back takes. Once you own a deep figure-four on the opponent’s arm, their attempts to posture, drive forward, or extract the limb supply the very momentum you need: you roll through the trapped shoulder, dragging them over the top while their arm stays loaded with submission pressure.
The rolling motion is what makes the technique punch above its weight. Rotational momentum multiplies the leverage on the shoulder far beyond what arm strength alone could generate, so size and strength matter far less than timing. The opponent is caught in a genuine dilemma: defend the kimura by keeping the elbow tight and they feed the sweep; fight the sweep by basing out and they expose the shoulder. When the roll completes you typically arrive in back control, in a top kimura trap, or, if the roll stalls, in a neutral turtle scramble rather than back on the bottom.
The technique works in both gi and no-gi, though the connection differs. In the gi, cloth grips on the sleeve or lapel supplement the figure-four and slow the opponent’s escape; in no-gi the lock relies on tight wrist-and-elbow control and a closer body connection because the reduced friction lets a sweaty arm slip. Either way, the roll itself, not the squeeze, is the engine, which is why the Rolling Kimura remains a cornerstone of the modern half guard and Kimura Trap attacking system.

Playing as Attacker
Key Principles
-
Secure a deep figure-four near the opponent’s elbow before committing to the roll, because a shallow wrist grip slips during rotation and surrenders the sweep
-
Let the opponent’s forward pressure power the roll; you supply the timing and direction, not raw strength
-
Keep your hips and chest connected to the opponent throughout the rotation so you sweep them with you instead of rolling away underneath them
-
Maintain constant shoulder pressure through the grip so every defensive choice feeds either the sweep or the submission
-
Initiate the roll when the opponent drives in or postures, not when they are settled and based wide; read their weight before you commit
-
Have your finish chosen before you roll: back control, top kimura trap, or crucifix, based on what their free arm and base are doing
-
Consolidate the instant the roll completes, because the transition window is where the position is won or lost
Execution Steps
-
Secure and deepen the kimura grip: From half guard or Kimura Trap bottom, lock the figure-four on the opponent’s arm: your near hand gr…
-
Read the weight and bait the drive: Keep your elbows tight and your hips live, threatening the shoulder lock just enough that the oppone…
-
Turn to your side and set the rolling angle: As they bring weight forward, turn onto the shoulder of your trapped-arm side and tuck that shoulder…
-
Initiate the roll, pulling the shoulder under: Drive off your feet and roll diagonally over your tucked shoulder, pulling the kimura grip tight to …
-
Stay connected and surface on top: Throughout the roll keep your chest and hips wrapped to the opponent so you come up on top of them, …
-
Read the landing and choose the finish: As you come up, assess what the opponent gave you. If their back is exposed, drive to back control a…
-
Consolidate the position immediately: Lock down your chosen finish without pausing. For back control, secure the seatbelt and both hooks w…
Common Mistakes
-
Rolling away from the opponent instead of rolling them over you
- Consequence: You spin out from under them and surface on the bottom or give up the grip, often ending in their guard or worse
- Correction: Keep your hips and chest wrapped to the opponent the whole roll; think of rolling around and over them, never away from them
-
Loosening the figure-four during the rotation
- Consequence: The opponent frees the arm, kills the submission threat, and rides out the roll to land on top
- Correction: The grip should tighten as you roll; the loaded shoulder is what drags them over, so glue the figure-four to your chest
-
Initiating the roll against a settled, wide base
- Consequence: There is no momentum to redirect, the opponent simply posts, and you burn energy spinning into a stuck position
- Correction: Bait or wait for the forward drive and roll on their weight coming in, not when they are heavy and based out
Playing as Defender
Key Principles
-
Win the grip fight early and strip the figure-four before it locks deep at your elbow, because a wrist-level grip is far easier to clear
-
Keep the threatened elbow pinned tight to your own ribs so the arm cannot be isolated or loaded
-
Maintain a wide, heavy base and avoid committing your weight blindly forward, since your forward drive is the fuel the roll needs
-
If the grip is locked, post the far hand and far leg to wall off the rotation before it starts
-
Protect the shoulder first and the position second; tap to genuine joint pressure rather than risking the arm to save the back
-
If you are being rolled, ride it and counter-roll to land on top rather than fighting to stay put and feeding the back take
-
Stay aware of the secondary branches, because basing wide invites the Old School sweep and turning in invites the back take
Recognition Cues
-
The bottom player threads one arm under yours and clamps a figure-four on your wrist, sliding the grip up toward your elbow
-
Your trapped wrist is dragged toward your own back, loading the shoulder and pre-setting the rotation
-
The bottom player turns onto the shoulder of your trapped-arm side and compacts their knees toward their chest
-
You feel rotational pressure building on your shoulder the instant you post or drive your weight forward
-
Their hips dig under yours and their chest wraps tight to you, the signature connection that precedes the roll
Defensive Options
-
Strip the figure-four with your free hand and retract the trapped elbow tight to your ribs - When: The instant you feel the grip being threaded under your arm or clamped on your wrist, before it locks deep at the elbow
-
Widen your base and post your far hand and far leg to wall off the rotation - When: When the figure-four is already locked but the roll has not started; keep your weight off the trapped side
-
Ride the roll and counter-roll, driving your weight through their rotation to land on top - When: When the roll is already underway and you cannot stop it; commit to coming out on top rather than resisting in place
Position Integration
The Rolling Kimura is a central branch of the Kimura Trap bottom system, sharing its figure-four grip with the Old School Sweep, the Kimura Sweep, and Kimura to Back Take. From half guard bottom the same grip that threatens the shoulder lock also off-balances the top player, so the Rolling Kimura is simply the reaction you choose when the opponent drives forward or rolls to relieve pressure rather than basing wide. Each defensive response opens a different branch: a wide base feeds the Old School sweep, a forward drive feeds the roll, and a turn into the grip feeds the back take. Understanding the Rolling Kimura as one spoke of this interconnected grip-based hub, rather than an isolated trick, is what lets you flow between sweeps, back takes, and submissions off a single point of control.
