Armbar
Classic elbow hyperextension attack from guard, mount, and back — one of the first submissions every white belt learns.
joint lock
Overview
The armbar attacks the elbow joint by trapping an arm between your legs and extending your hips. It appears in every major position — closed guard, mount, side control, and back — making it essential for both gi and no-gi grappling.
#Setup
- Isolate one arm and control the wrist while your legs cut across the opponent’s chest or face.
- Pinch knees together above the elbow and pull the arm so the thumb points up.
- Slide hips close to the shoulder and remove space under the elbow.
#Execution
- Fall or sit to the finishing angle with the arm trapped between your thighs.
- Pinch knees, flex feet, and lift hips while keeping the wrist pulled to your chest.
- Bridge upward gradually until the elbow hyperextends or the opponent taps.
#Finishing
- Keep hips tight to the shoulder — space allows the elbow to escape.
- Control the wrist throughout; never finish with a loose grip.
- Release immediately on the tap.
⚠️
Safety Note
Armbars hyperextend the elbow quickly. Apply hip pressure gradually, avoid slamming into a stacked finish, and release immediately on tap.
Primary Targets
- Elbow
- Shoulder
Key Concepts
- Thumb up, hips close, knees pinching above the elbow.
- Angle beats strength — rotate 90 degrees before extending.
- Attack chains beat single attempts; threaten triangle when they hide the arm.
Primary Entries
- Mount when the opponent pushes into you with extended arms.
- Closed guard after breaking posture and isolating an arm.
- Failed triangle when the opponent posts a hand to defend.
Defenses & Counters
- Expect stacks that pin your hips — create angle and keep the wrist before extending.
- Watch for hitchhiker rolls and arm hides that clear the elbow line; follow or switch to triangle/omoplata.
- If they clasp hands, break the grip or attack the free side rather than muscling through.
Follow-Ups
- Triangle choke when they stack or hide the arm inside.
- Omoplata if they turn away from the finishing angle.
- Back take when they roll to escape the lock.
- Triangle choke when the opponent stacks or hides the arm.
- Omoplata when they turn away from the armbar angle.
Training Drills
- Hip-escape to armbar flow from closed guard.
- Mount armbar entries with progressive resistance.
- Triangle-to-armbar chain rounds with timed reactions.

Summary
Master angle, hip placement, and knee control before power. The armbar rewards patience and appears everywhere once you learn to isolate the arm.
