BJJ Armbar Guide: Setup, Finish & Positions
The armbar is one of the first submissions every BJJ student learns, and one of the last that elite black belts still rely on. Here is how to finish it correctly.
What the Armbar Does
The armbar attacks the elbow. You control your opponent's arm, trap it between your legs, and extend your hips. Your body becomes a lever. Their elbow becomes the fulcrum. It works from almost every position: mount, guard, side control, and the back.
The armbar traces back to judo, where it's called juji-gatame. BJJ adopted it early and never let go. It remains one of the first submissions most white belts learn, and one of the last submissions elite black belts still rely on.
Setting It Up From Closed Guard
- Control one of your opponent's wrists and pull it across your centerline.
- Angle your hips out to the same side as the trapped arm.
- Bring your other leg up and over their head.
- Squeeze your knees together, pinning the arm between your thighs.
- Extend your hips upward while pulling the wrist down toward your chest.
The One Rule That Matters Most
Keep the thumb pointing up. If your opponent's thumb points toward the ceiling as you finish, you're attacking the elbow correctly. If it points sideways, you're off-angle and the lock won't work no matter how hard you extend your hips.
Common Mistakes
- Extending your hips before fully controlling the arm, giving your opponent room to pull free.
- Leaving a gap between your knees, which lets them bend the arm and escape.
- Finishing with your back flat instead of arched, which weakens the lever.
- Forgetting to control their far hip, which lets them roll out of the position entirely.
Defending the Armbar
The moment your arm gets isolated, clasp your hands together and pull your elbow tight to your body. This is the "hitchhiker" escape. From there, try to stack your opponent by driving your weight forward, which takes away their leverage and lets you pass or stand up.
Gi vs No-Gi
The armbar works identically with or without a gi. Sleeve grips can help control the wrist in the gi, but the core mechanics never change: isolate the arm, control the elbow, extend the hips.
Once you're comfortable finishing the armbar, our triangle choke guide and kimura guide share several of the same control principles from closed guard.

Frequently Asked Questions
Why does my armbar keep slipping?
Usually a gap between your knees or hips extended before the arm is fully controlled. Squeeze your knees together and secure the wrist before you extend.
Is the armbar legal at white belt?
Yes. It is legal at every belt level in IBJJF competition and is one of the first submissions most schools teach.
How do I defend an armbar once my arm is straight?
Clasp your hands together and pull your elbow tight to your body, then stack your opponent by driving your weight forward to take away their leverage before it fully locks out.
Does the armbar work in no-gi?
Yes. The core mechanics never change with or without a gi. Sleeve grips can help control the wrist in the gi, but isolating the arm and extending the hips works the same either way.
