Arm in a kimura

Position · Closed Guard

He holds your wrist with one hand and has his other arm over your arm, grabbing his own wrist — a figure-four — and starts turning your hand toward your back. Grab your own hand, belt or pants to lock the arm, keep the elbow tight to your ribs and your wrist close to your body. If the hands are still joined, turn toward him and drive the elbow back to the mat for the Kimura Defense, or roll with the rotation when the shoulder is bent too far. His goals are to pry your grip free, step over your head and turn the shoulder. Do not let the elbow drift away from your body: once the arm is behind your back, tap.

How to do it

  1. Grab your own belt or pants with the attacked hand as soon as they catch the wrist. The grip anchors your hand in front of your hip so they cannot fold the arm behind your back.
  2. Keep the elbow tight to your ribs and the arm bent. The kimura needs your elbow off your side to turn the shoulder.
  3. Turn into them, chest to chest, bringing the attacked shoulder close to their body. This turns the shoulder the opposite way to the lock and takes away their space.
  4. When their grip loosens, pull the arm free along your body, elbow first, and recover guard.

Key details

  • The grip on yourself holds the arm: their two arms against your one arm plus your anchor in the belt.
  • Turn in, never away: turning away rotates the shoulder in the same direction as the lock.
  • Tap when the hand reaches your back: from there the shoulder is already in the lock.

Common mistakes

  • Turning away from them. — The shoulder turns deeper into the lock. — Turn your chest towards them.
  • Letting the elbow move away from the body. — They take the arm behind your back. — Glue the elbow to your ribs.
  • Waiting for pain before tapping. — The shoulder tears before it hurts. — Tap as soon as the shoulder turns.

If they defend

  • They break your belt grip. → Grab your wrist or tap.
  • They switch to an armbar. → Thumb down and stack.

How to drill it

Partner sets a slow kimura, you grip and turn in, 8 each side.

Safety

Tap early: shoulder locks give little warning.
