SAFETY: Kimura from Mount targets the Shoulder joint (glenohumeral joint, rotator cuff). Risk: Rotator cuff tear (supraspinatus, infraspinatus, teres minor). Release immediately upon tap.

The Kimura from Mount represents one of the highest-percentage shoulder lock attacks in Brazilian Jiu-Jitsu, combining the dominant control of mount with the mechanical advantage of the double-wrist grip. This submission targets the shoulder joint through a figure-four grip configuration that isolates the opponent’s arm while leveraging superior positional control. From mount, the attacking grappler can transition seamlessly between maintaining positional dominance and applying submission pressure, creating a strategic dilemma where defensive movements often expose additional attacks. The technique’s effectiveness stems from the ability to use bodyweight, hip pressure, and precise angle creation to generate overwhelming torque on the shoulder capsule. Unlike Kimuras from other positions, the mount variation offers exceptional control over the opponent’s ability to roll or escape, making it particularly reliable in both training and competition scenarios. The submission can be finished while maintaining mount or used as a transition mechanism to take the back or establish other dominant positions.

Key Attacking Principles

What are the key principles for executing Kimura from Mount?

  • Establish dominant mount control with heavy hip pressure before attempting the submission
  • Secure the figure-four grip with maximum distance between your hands to create leverage
  • Control the opponent’s elbow position - keep it tight to their body during setup
  • Create the proper angle by positioning your body perpendicular to opponent’s trapped arm
  • Apply rotational pressure in a circular motion toward opponent’s head, not straight up
  • Maintain mount control throughout the submission to prevent escapes or counters
  • Use progressive pressure application - build torque gradually to allow safe tapping

Prerequisites

What do you need before attempting Kimura from Mount?

  • Establish stable high mount or S-mount position with hips low and heavy
  • Control opponent’s near arm by isolating it away from their body
  • Secure initial wrist control with your same-side hand (right hand to opponent’s right wrist)
  • Break opponent’s defensive frames or grips using weight distribution and pressure
  • Position your chest and shoulder pressure to limit opponent’s movement and breathing space
  • Create angle by shifting your hips toward the trapped arm side
  • Ensure opponent cannot use their free hand to defend the trapped arm effectively

Execution Steps

How do you execute Kimura from Mount step by step?

  1. Establish Mount Control and Isolate the Arm: From high mount, use your chest pressure and hip control to pin opponent flat. Bait or force their arm across their body by threatening attacks to the opposite side, or wait for them to frame against your chest. When the arm extends, immediately trap their wrist with your same-side hand (if attacking right arm, use your right hand). Pin their wrist to the mat or their chest to prevent retraction. (Timing: 2-3 seconds to establish position)
  2. Feed the Wrist and Secure Figure-Four Grip: While maintaining wrist control, thread your opposite hand (left hand for right arm attack) underneath their elbow and grip your own wrist, creating the figure-four configuration. Your grip should be as deep as possible on your wrist - the further from their arm you grip, the more leverage you create. Keep their elbow bent at approximately 90 degrees and tight to their torso during this transition. (Timing: 1-2 seconds for grip transition)
  3. Create Angle and Establish Base: Shift your hips and upper body toward the trapped arm side, creating a perpendicular angle to their body. Your chest should now be oriented toward their head rather than directly down on their torso. Maintain one knee tight against their ribs on the trapped arm side while extending the other leg for base. This angle is critical - it aligns your body mechanics for optimal torque application. (Timing: 1-2 seconds for positional adjustment)
  4. Lift the Elbow and Control Height: Using your figure-four grip, lift their elbow off the mat while keeping their hand pinned toward their body or the mat. The elbow should rise to approximately the height of their ribcage or slightly higher. This creates the necessary leverage arm for the submission. Keep their wrist close to their body - if their hand moves too far from their torso, the submission loses effectiveness. (Timing: 1-2 seconds)
  5. Walk Hands Toward Head: While maintaining elbow height and grip integrity, begin moving their hand in a circular arc toward their head. The motion should be smooth and controlled, rotating the shoulder internally. Your hands move together as a unit - do not pull with one hand more than the other. The pressure increases progressively as you move through the arc. Watch for the tap, which typically comes when their hand reaches ear level. (Timing: 3-5 seconds progressive application)
  6. Finish or Transition: Continue the circular rotation until opponent taps. If they resist strongly or begin to roll, be prepared to transition: maintain your figure-four grip and follow their roll to take the back, or step over their head into an armbar position. Never release the grip prematurely - the Kimura control allows multiple submission and positional options even if the shoulder lock itself doesn’t finish immediately. (Timing: Until tap or transition initiated)

Opponent Defenses

How might your opponent defend against Kimura from Mount?

  • Grabbing their own gi pants or belt (defensive grip) (Effectiveness: Medium) - Your Response: Maintain pressure and use your bodyweight to break the grip by continuing the circular motion. Alternatively, post your hand on their head and use leverage to force their hand away from their body, then complete the arc toward their head. → Leads to Mount
  • Rolling toward the trapped arm to relieve pressure (Effectiveness: Low) - Your Response: Follow the roll while maintaining figure-four grip. As they roll, transition your legs to take the back with seat belt control, or use the momentum to transition to a crucifix position. The Kimura grip remains secure throughout the transition. → Leads to Closed Guard
  • Bridging explosively to disrupt base and mount control (Effectiveness: Medium) - Your Response: Lower your hips and widen your base immediately when you feel the bridge. Post your head on the mat on the trapped arm side to prevent being swept. Keep the figure-four grip locked and maintain elbow height - even if mount is threatened, the submission pressure continues. → Leads to Closed Guard
  • Straightening the trapped arm to prevent rotation (Effectiveness: Low) - Your Response: If they straighten the arm, you gain access to a straight armbar. Simply adjust your angle, bring your leg over their face, and fall back for the armbar. The Kimura grip naturally transitions to armbar control when they extend. → Leads to Mount
  • Using free hand to push your face or create distance (Effectiveness: Low) - Your Response: Pin their pushing hand with your head pressure or trap it with your free knee. Alternatively, threaten to transition your attack to their free arm, forcing them to retract the defensive hand. Your mount control and figure-four grip remain primary throughout. → Leads to Mount

Common Attacking Mistakes

What mistakes should you avoid when executing Kimura from Mount?

1. Releasing mount pressure while attempting the submission

  • Consequence: Opponent escapes mount position, or successfully bridges and reverses position before submission can be secured
  • Correction: Keep your hips heavy and low throughout the entire sequence. Your weight should constantly pressure down through your knees and hips into opponent’s torso. Never sacrifice positional control for submission speed.

2. Gripping too close to opponent’s arm on the figure-four (hands too close together)

  • Consequence: Insufficient leverage to generate adequate shoulder torque - submission lacks power and opponent can easily defend
  • Correction: Grip your own wrist as far from opponent’s arm as possible. Maximum distance between your hands creates maximum leverage. Extend your bottom arm fully when establishing the figure-four.

3. Lifting straight up instead of rotating in circular arc toward head

  • Consequence: Incorrect pressure angle fails to engage shoulder joint properly - submission feels weak and opponent can resist indefinitely
  • Correction: The motion must be circular and rotational, not linear. Move their hand in an arc toward their head while maintaining elbow height. Think of stirring a large pot rather than lifting a weight.

4. Allowing opponent’s hand to move away from their body

  • Consequence: Loss of mechanical advantage and submission pressure - arm position becomes too extended for effective shoulder lock
  • Correction: Keep their wrist pinned toward their body or chest throughout. The closer their hand stays to their torso, the more effective the rotational pressure on the shoulder joint.

5. Failing to create proper perpendicular angle before applying pressure

  • Consequence: Poor body positioning reduces leverage and allows opponent to defend easily or escape mount
  • Correction: Before attempting the finish, ensure your chest is perpendicular to their body, oriented toward their head. This angle alignment is essential for generating proper torque while maintaining mount control.

6. Applying explosive or jerking rotational pressure

  • Consequence: CRITICAL SAFETY VIOLATION: Can cause immediate rotator cuff tear, shoulder dislocation, or labrum damage without giving opponent time to tap safely
  • Correction: ALWAYS apply progressive, smooth pressure over 3-5 seconds minimum in training. The submission should build gradually, allowing clear opportunity to tap. Save competition speed for competition only.

7. Continuing pressure after hearing popping or clicking sounds from shoulder

  • Consequence: CRITICAL SAFETY VIOLATION: Joint sounds indicate structural damage is occurring - continued pressure causes severe injury requiring surgery
  • Correction: IMMEDIATELY release all pressure at first sign of joint noise. Follow release protocol and check partner’s shoulder health before resuming. Joint sounds are not normal and indicate injury in progress.

Training Progressions

How do you train Kimura from Mount (Attacker)?

Phase 1: Grip Mechanics and Mount Retention - Figure-four grip configuration and maintaining mount during submission attempts Practice establishing the figure-four grip from mount with a compliant partner at 0% resistance. Focus on proper hand placement distance, wrist depth, and threading the arm under the elbow. Drill mount retention separately, maintaining position while partner performs light bridge and hip escape attempts. Combine both elements only after each is comfortable individually. 20 repetitions per side per session.

Phase 2: Dominant Angles and Pressure - Body positioning, perpendicular alignment, and controlled rotational mechanics With the grip established, practice shifting to the perpendicular angle while maintaining mount pressure. Partner provides 25-50% resistance. Focus on the circular arc motion toward the head at slow, controlled speed. Drill elbow elevation and wrist proximity to the body. Partner provides verbal feedback on pressure direction and intensity. Emphasize the progressive pressure curve over 3-5 seconds minimum.

Phase 3: Counter Recognition and Transition Chains - Reading defensive reactions and flowing to alternative attacks or positions Partner provides specific defensive reactions in sequence: grip defense (grabbing belt/pants), rolling toward trapped arm, bridging, arm extension. Practice the correct response to each: grip breaking mechanics, following the roll to back control, base adjustment against bridges, and transitioning to armbar on extension. 50-75% resistance with emphasis on maintaining the figure-four grip throughout all transitions.

Phase 4: Live Application and Competition Simulation - Full-resistance positional sparring from mount with Kimura as primary attack Begin positional sparring rounds from mount with full resistance. Top player works to establish and finish the Kimura or transition to alternative submissions. Bottom player uses all available defenses. 3-minute rounds with role switching. Track submission rate and identify patterns in defensive responses. Develop automatic recognition of when to commit to the Kimura finish versus when to transition to back control, armbar, or reset to mount.
