The kimura from side control works by locking a figure-four grip on the far arm, pinning the elbow to the hip before cranking, then stepping over to finish with rotation instead of arm strength. Beginners lose it most often by cranking too early or losing the grip mid-transition.
Why the Kimura From Side Control Is Worth Drilling First
The kimura from side control is one of the first real submissions most white belts land on a resisting partner because it does not depend on speed or strength. It works off grip, angle, and a rule about the elbow — not a scramble. That makes it a good place to start building a submission game from top position.
I teach this one early in private lessons at Darfight in Brighton Beach because it forces a student to slow down and feel the mechanics instead of yanking on an arm and hoping. Once you understand why it works, you start seeing the same grip and the same angle everywhere else — half guard, mount, even standing.
The Kimura Grip: What You're Actually Holding
The kimura grip is a figure-four on your opponent's wrist and forearm, built with your own two hands, not a sleeve or a collar. You are not grabbing the wrist with one hand and hoping — you are locking a bent-arm figure-four that gives you two points of leverage against their shoulder.
From side control, the far-side arm is the target. Their arm needs to be somewhere near their own hip or chest for this to make sense; if it is already stiff-armed out and away from their body, you are usually looking at an armbar or a different attack instead, not a kimura.
- Trap the wrist first with your near hand, thumb-side down, so the wrist can't rotate free
- Reach under or over their arm with your other hand and grab your own wrist, forming the figure-four
- Keep both elbows tucked tight to your own ribs while you set the grip — a loose figure-four is the whole problem
The Elbow-to-Hip Rule
The elbow-to-hip rule is simple: before you crank anything, their elbow needs to be pinned to their own hip or ribs, not floating in space. If the elbow is away from the body, the kimura grip alone won't finish anything — they'll just roll their shoulder and swim the arm back out.
This is the single biggest thing beginners skip. They get the figure-four grip, feel strong, and start cranking with the elbow still hanging out in the middle of the mat. All that does is give the bottom person room to posture, turn into you, or start defending with their free hand. Pin the elbow to the hip first. Everything else follows from that one detail.
The Step-Over: Taking the Back Route to the Finish
The step-over is how you go from side control to a finishing position without losing the grip you just built. Once the figure-four is locked and the elbow is pinned, you step your near-side leg over their head and drop your hip to the mat on the far side, effectively moving into a north-south-adjacent position with their arm still trapped.
From there you're not muscling the arm up — you're rotating your whole body and driving your hip down while keeping the figure-four tight. The rotation, not your arms, is what actually taps people. This is also the same step-over you'll eventually use to take the back or transition to mount if the kimura doesn't finish, so it's worth drilling on its own even before you add resistance.
A Note on Pace
Go slow the first dozen reps. The kimura is a shoulder lock — tap early in drilling and communicate with your partner, because a shoulder doesn't give you much warning before something feels wrong. This is standard practice for any submission, not unique to the kimura, but it matters more here because the grip locks up fast.
Two Ways Beginners Lose the Kimura From Side Control
The two most common ways beginners lose this submission both come from rushing the setup instead of trusting the grip. Fix these two things and your kimura success rate on resisting partners goes up more than any drill will do on its own.
- Cranking before pinning the elbow — the figure-four feels strong in isolation, but without the elbow pinned to the hip the opponent rolls their shoulder and swims free, or worse, uses the space to shrimp and recover guard
- Losing the grip during the step-over — moving your body before your hands are truly locked lets the trapped arm slip out during the transition, which is usually a grip problem, not a strength problem; re-set the figure-four tighter before you move your legs
Both of these show up constantly in side control escape work too, from the other side — a bottom player who understands the elbow-to-hip rule knows exactly when to keep the arm tucked and deny the grip in the first place.
Drilling This Without a Coach Watching Every Rep
You can drill the grip and the elbow position slowly with a cooperative partner, but the step-over and the actual finish are hard to self-correct without someone checking your hip angle and grip tightness in real time. This is exactly the kind of detail that gets lost in a crowded group class where the instructor can't watch every pair.
In a private lesson I can put you in side control, have you build the grip, stop you the moment the elbow drifts off the hip, and reset until it's automatic. That's the difference between knowing the steps and actually having the submission live under private lesson pressure. If you want the full picture of where this sits in a beginner's first sessions, what to expect in a first private lesson covers the basics of how that structure works.
Where This Fits in the Rules
The kimura is legal at every belt level in gi and no-gi, unlike some leg attacks that carry restrictions for lower belts. You can check the full technique restrictions by belt in the IBJJF rule book.
Booking Time to Drill This One-on-One
If you want to actually own the kimura from side control instead of half-remembering it from a video, book time on the mats at Darfight in Brighton Beach — B and Q trains stop right at the station. Sessions run solo or with a partner splitting the mat time, and you can see current pricing and session options before you pick a slot.

Questions people ask
Why does my kimura from side control keep failing even with a tight grip?
A tight figure-four grip alone doesn't finish anything if the elbow isn't pinned to the hip first. Most failed kimuras happen because the person cranks before the elbow is pinned, which gives the opponent room to roll their shoulder and swim the arm free.
Do I need to step over to finish a kimura from side control?
Not always, but the step-over gives you a cleaner angle by using body rotation instead of arm strength to finish, and it sets up a transition to the back or mount if the submission doesn't land.
Is the kimura legal for beginners in competition?
Yes, the kimura is legal at every belt level in both gi and no-gi under IBJJF rules, unlike some leg attacks that carry restrictions for lower belts. Check the full IBJJF rule book for complete details.
Can I drill the kimura setup without a coach correcting me?
You can drill the grip and elbow position slowly with a cooperative partner, but the step-over and finish are hard to self-correct without someone watching your hip angle and grip tightness in real time.
