SAFETY: Kimura from Modified Mount targets the Shoulder joint, rotator cuff, and shoulder capsule. Tap early and often. Your safety is more important than any training round.
Defending the Kimura from Modified Mount requires understanding that the opponent’s asymmetric positioning creates both a dangerous submission threat and exploitable structural weaknesses. The posted leg provides the attacker with stability, but it also means their weight is unevenly distributed — the posted-leg side has less control pressure, which becomes your primary escape direction. Your defensive priorities are layered: first, prevent wrist isolation by keeping your near-side arm tight to your body; second, if the wrist is captured, prevent the figure-four from being threaded by straightening the arm; third, if the figure-four is locked, prevent the wrist from being pinned to the mat. Each layer buys time and creates opportunities to bridge, hip escape, or force the attacker to abandon the submission. The critical safety awareness is recognizing when to tap — once the wrist is pinned to the mat and rotation begins, the shoulder joint is in immediate danger, and attempting to muscle out risks catastrophic injury to the rotator cuff.
Opponent’s Starting Position: Modified Mount (Top)
How to Recognize This Submission
How do you know when someone is attempting Kimura from Modified Mount?
- Attacker’s hand reaches for your near-side wrist on the posted-leg side while maintaining chest pressure through the across-body knee
- You feel the attacker’s second hand sliding under your elbow or tricep area, attempting to thread the figure-four grip
- Attacker begins incrementally walking your wrist away from your body using small hand-over-hand movements (paint brush technique)
- You feel the figure-four grip lock around your arm — your wrist controlled by one hand and the attacker’s other hand gripping their own wrist under your elbow
- Attacker drives your wrist toward the mat beside your head while increasing chest pressure to prevent you from turning
Key Defensive Principles
What are the key principles for defending Kimura from Modified Mount?
- Keep the near-side arm glued to your body with elbow tight to your hip — wrist isolation is the attacker’s first step and your first line of defense
- If the wrist is captured, straighten the arm immediately to prevent the figure-four threading — a straight arm cannot be Kimura-locked
- Escape toward the posted leg side where the attacker’s weight distribution is weakest and structural control is most compromised
- Frame on the attacker’s hips rather than chest — hip frames create space for escape without exposing your arms to isolation
- Recognize the point of no return — once the wrist is pinned to the mat with a locked figure-four, tap immediately rather than risking shoulder injury
- Use the attacker’s commitment to the Kimura grip as an opportunity to bridge and escape, since both their hands are occupied and cannot post
Defensive Options
What can you do to defend against Kimura from Modified Mount?
1. Grip your own belt, shorts, or opposite wrist to anchor the near-side arm against your body
- When to use: Early stage — as soon as you feel the attacker reaching for your wrist. This is your strongest and most energy-efficient defense.
- Targets: Modified Mount
- If successful: Prevents wrist isolation entirely, forcing attacker to either break your grip or abandon the Kimura for another attack
- Risk: Attacker switches to americana or uses paint brush technique to incrementally break your grip anchor
2. Straighten the arm completely to prevent figure-four threading
- When to use: Mid stage — if the attacker has isolated your wrist but has not yet completed the figure-four grip under your elbow
- Targets: Modified Mount
- If successful: A straight arm prevents the figure-four from locking. The attacker must either re-bend your arm or abandon the Kimura.
- Risk: A straight arm is the prerequisite for an armbar — the attacker may immediately chain to an armbar transition instead
3. Bridge toward the posted leg and hip escape to recover guard
- When to use: When the attacker has committed both hands to the Kimura grip, removing their ability to post against your bridge
- Targets: Closed Guard
- If successful: Creates enough space to hip escape and recover closed guard or half guard, escaping both the mount and the submission
- Risk: If the bridge is poorly timed, the posted leg absorbs the momentum. The attacker may also follow your bridge while maintaining the Kimura grip.
4. Turn into the attacker to close the shoulder angle and reduce rotational pressure
- When to use: Late stage — if the figure-four is locked and the wrist is being driven toward the mat. Turn your body to face the attacker to reduce the effective rotation angle.
- Targets: Closed Guard
- If successful: Relieves immediate shoulder pressure and may create enough space to extract the arm or transition to a scramble
- Risk: The across-body knee may prevent effective turning. If only partially successful, you may end up in a worse position with the Kimura still locked.
Escape Paths
How do you escape Kimura from Modified Mount?
- Bridge toward the posted leg and hip escape to recover half guard or closed guard while the attacker’s hands are committed to the Kimura grip
- Straighten the arm to defeat the figure-four and immediately frame on the attacker’s hips to create space for a hip escape
- Turn into the attacker to close the shoulder rotation angle, then use the turning momentum to drive into a scramble position
Best-Case Outcomes for Defender
What is the best outcome when defending Kimura from Modified Mount?
→ Closed Guard
Bridge explosively toward the posted leg when both of the attacker’s hands are committed to the Kimura grip, then hip escape and recover closed guard by locking your legs around their waist before they can re-establish mount control
