This technique carries a high risk of serious injury, especially to the wrist joint. Do not attempt without qualified instructor supervision. Beginners should build fundamental grappling skills first.
Learn BJJ wrist locks: how to apply them from guard, mount, and standing, why they work as surprise submissions, and safety considerations.
Wrist locks are legal at all IBJJF belt levels yet are massively underused β making them high-percentage surprise submissions. Because defenders rarely train wrist lock defense, a well-timed wrist lock often catches black belts.
| Position | Setup | Application |
|---|---|---|
| From Guard | They post hand on your stomach | Grab wrist, fold fingers back, rotate |
| From Mount | They frame against your hips | Trap the wrist against your thigh and fold |
| From Side Control | Near arm extended | Figure-four the wrist while controlling |
| Standing (Clinch) | Grip break attempt | Redirect their grip into a wrist fold |
All wrist locks work by hyperextending or rotating the wrist joint beyond its natural range of motion. The key is controlling the elbow β if the elbow is controlled, the wrist cannot escape the torque.

While both attacks target the arm, a kimura is a shoulder lock that uses a figure-four grip to hyperextend the shoulder. A wrist lock, on the other hand, targets the wrist joint itself, often by bending it in a way it's not designed to move.
The primary defense is to keep your wrist straight and avoid allowing your opponent to isolate and bend it. Maintaining a strong grip and immediately attacking their base or posture can also disrupt their setup for a wrist lock.
