What is the Wrist Lock?
Wrist locks attack the wrist by controlling the hand and forcing it beyond its normal range, usually with your chest, forearm, or figure-four structure. They appear when opponents post hands on the mat, frame with stiff wrists, or leave fingers exposed during grip fights. In IBJJF adult divisions they are generally illegal at white belt and legal from blue belt up — confirm your ruleset.
Setup
- Isolate one hand so the fingers or palm cannot escape your control.
- Pin the hand to your chest, stomach, or the mat to remove slack.
- Align the wrist for either hyperflexion (palm toward forearm) or hyperextension depending on the grip.
Execution
- Use your body — not just finger strength — to bend the wrist past its end range.
- Keep the elbow of the trapped arm from circling free; body position matters.
- Apply pressure gradually; wrist locks tap quickly when the line is correct.

Safety Warning
Wrist locks can injure ligaments and small joints with very little warning. Use slow pressure in training, avoid cranking posted hands explosively, and know whether wrist locks are legal in your division before competing.
Primary Targets
- Wrist
Key Concepts
- Control the hand to your body; chasing fingers in space fails.
- Body pressure finishes more reliably than hand strength.
- Opportunistic timing beats forcing wrist locks as a primary closed-guard plan.
Primary Entries
- Closed guard when they post a hand on your torso or mat.
- Mount or side control when they frame with a straight wrist.
- Grip breaks where fingers remain exposed after a sleeve or collar peel.
Defenses & Counters
- Expect them to make a fist and pull the elbow free — recapture the hand to your chest.
- Watch for posture snaps that clear your control; switch to a larger joint attack.
- If they roll the wrist out, abandon rather than ripping fingers.
Follow-Ups
- Kimura when the wrist escapes but the elbow stays available.
- Americana from mount/side on the same framed arm.
- Omoplata if they posture into a shoulder-line exposure from guard.
Training Drills
- Closed-guard posting-hand recognition drills to a light tap
- Mount frame-to-wrist-lock entries with cooperative partners
- Grip-fight rounds ending in controlled wrist exposures (training only)

Summary
Wrist locks are opportunistic finishes: trap a posted or framed hand to your body, bend with torso pressure, and tap early. Train them slowly, and verify belt/rules legality before using them in competition.
