The kimura trap transforms a single shoulder lock into a complete positional and submission system. Once you control the kimura grip, you have access to the kimura finish, back takes, armbar entries, and guard passes — all from one grip.
The kimura grip is a figure-4 arm control: your hand grabs their wrist, your other arm passes under their elbow and grabs your own wrist. This creates a powerful lever against the shoulder joint.
Rotate their arm toward their back, moving their hand toward their shoulder blade. The shoulder joint has a limited external rotation range — when exceeded, the tap comes quickly.
When they defend the finish by rolling, follow the roll and take their back. The kimura grip controls their arm as you climb onto their back for seat belt control.
If they straighten their arm to defend the kimura rotation, transition immediately to an armbar. Their defense becomes your setup for a different submission.
From top half guard or side control, use kimura grip to control their arm while you pass. The arm control prevents their guard recovery and framing.
Attack kimura from closed guard by controlling their wrist and bumping their elbow up. Pull their arm across your chest before executing the rotation.
