Danaher - Kimura vol1

Mechanics of Kimura

System Overview

7 Kimuras

  1. Figure 4 - most common kimura
  2. Figure 4 Bicep - rnc type grip
  3. Cross Kimura - legs are employed
  4. Kimura Plata - mix between kimura and omoplata
  5. Trimura - triangle and kimura hybrid
  6. One Hand - single hand
  7. Legs Kimura - legs are used from beginning - attack against turtle

Foundation is the figure 4 kimura

Application of fig 4 creates the central problem - Hand behind back?

Hand Behind

  • Top Position -> Establish Top Powerline
  • Bottom Position -> Establish Bottom Powerline

Hand in Front

  • Employ Legs to Increase Power -> Cross Kimura -> Kimura Plata
  • Switch to Another Submission -> e.g. Armbar, Triangle
  • Switch to Another Position -> T Kimura, Head and Arm Kimura

If you get the hand behind go directly to submission hold

Two distinct powerlines - top and bottom

Otherwise you have to work when your opponent’s hands are in a strong defensive position

You can use your legs against opponents arms to force opponent’s hand behind their back

Core Concepts

  • Multiplicity Principle - never limit to one variation of a submission
  • Front Back Asymmetry - when hands are in front they are strong and coordinated (opposite when they are back)
  • Arms Legs Asymmetry - legs are much stronger than arms, use them to bring their arm behind their back
  • Head Chancery Principle - almost all effective defence comes down to opponent moving their head around. also when the head can’t move the shoulder becomes more vulnerable
  • Power from Position Principle - there is a powerline from top and bottom that will increase the power dramatically
  • Gateway Principle - gateway to many other positions and submissions

Trinity of Power

Best place to start is side kimura

Single clearest way to illustrate principles

Opponent is on their back

  • Hand relatively close to back
  • Almost all escapes involve opponent moving head
  • Further elbow is away from the shoulder line, worse the kimura is
  • You want elbow, shoulder and shoulder in a line
  • You can use your legs as part of the attack
  • Hands are the transmitters of power, legs and hips are backbone
  1. Always control your opponents head
  2. Shoulder line - elbow, shoulder, shoulder
  3. Use your legs and hips as backbone of power

Thumb or no Thumb

  • If you can turn your opponents forearm with thumbs it would add to breaking power
  • If your opponent is strong, your hand just rotates around their wrist
  • Position of your thumb is not critical to breaking power
  • General rule, smaller wrist opponent - use your thumb
  • Bigger wrist opponent - no thumbs
  • Don’t obsess over thumbs - in regards to breaking power
  • When setting up kimuras - thumbs matter

Essential nature of Kimura - A Twisting Lock

  • Linear lock - arm bar
  • With any twisting lock we have a pull hand and a push hand
  • Degree of arm is variable
  • Best kimuras are when the arm has less than 90 degrees (quite bent)
  • One hand provides a push on the wrist, the other arm pulls on the elbow
  • The push hand can often be used to simply “stop” the opponents hand

Hand and Arm Positioning

  • Grabbing opponents hand
  • Grabbing the wrist is further down the lever than optimal
  • Grabbing the fingers is grabbing over a flexing joint (even though lever length is long)
  • Best compromise is to grab right on the wrist

When grabbing your own hand

  • Bring your wrist where there is physical contact with your opponents wrist
  • There should be no daylight between your hands

Your elbow

  • Bring your elbow out as far as possible towards your opponent’s elbow
  • Push your elbow out to increase the pulling power
  • You want your elbow where their elbow is

Bending a Straightened Arm

Should your opponent’s arm be more or less than 90 degrees

Preference for arm bent more

From a relatively straight arm position

  • Opponent’s back is on the mat, so you can’t bend their arm behind their back
  • Put up a support leg (top leg by their head)
  • Point your elbow towards the ceiling (lean towards their legs)
  • This takes their back off the floor
  • Throttle your wrists like a motorcycle - over the top!
  • Bring their arm behind their back

Diagonal Power Line

  • 1 of the most crucial aspects of kimura
  • typically people try to attack kimura from a perpendicular angle
  • you want to line up your body from your opponent’s far hip to their near shoulder
  • your hip should dominate their close shoulder
  • your shoulder (side close to their feet) should dominate their far hip when getting the kimura
  1. walk forward and step over your opponent’s head
  2. bring your head up , straight back, towards their hip
  • your hip must come up upon their shoulder
  • step over their head

test this out with a no-hands kimura

try to just use the pulling hand to see if you can get the kimura

Pull Dominant Kimuras vs Push Dominant Kimuras

  • If you are pushing the shoulder their is a lot of movement in the shoulder
  • Rather than pushing, immobilise their hand and pull their elbow
  • Only way you can do it if your head moves back away
  • Create immobility in the hand and immobility in their head

Beating the Shoulder and Trapping Head

  • If your opponent is going to escape, they have to escape their head
  • Most defensive opponents will keep a near hand in on your hip
  • First problem to deal with is the framing near hand
  • Bring your hips up higher and point them towards your opponents feet
  • Twist your hips back, beat their arm and get your hip on the shoulder
  • Step your leg over their head
  • Don’t collapse the leg (even though it will trap their head better)
  • Keep the foot active so you can push off the floor

Shoulder Line

  • The elbow should be on the shoulder line (even if you can’t bend the arm in)
  • First bring your head over the elbow
  • Pull their elbow to the shoulder line
  • If their elbow is low, kimura is very hard

A Vexing Problem

  • When you are starting to get the kimura
  • You can’t reach your own wrist
  • Temptation is to bring the hand up - can be very bad
  • In this case, use a thumb grip
  • If your hands are unlocked and you don’t use thumbs your opponent can pummel out
  • Opponent is doing a good job of keeping their arm straight (so you can’t lock)

First method

  • Bring your body close and bring your elbow to theirs
  • Pull them up, turn the wrist in. Then you can grab your own wrist

Second method

  • Shorten the method by bringing your grip up on their arm
  • Once you lift them up adjust your grip back down their arm

Essential Skill of Kimura System - Roll Through Kimura Scrambles

  • Focus on keeping your opponents hand behind their back when in scrambles
  • A big part of the initial gambit is keeping your opponents head down when you bring your opponent’s back up
  • If your opponent sits up while you do this do not let go of the grip
  • Have confidence in the hand behind their back
  • Do not stay on the same side of their body (they can get the hand in front)
  • Bring your head to their elbow (dive over them kinda)
  • Continue to roll them over til you are back on top again
  • Make sure to cover their head with your leg as you come back up
  • Because mechanics are so good for you, you can give up position
