SAFETY: Kimura from Crucifix targets the Shoulder joint, rotator cuff, and shoulder capsule. Risk: Rotator cuff tear (supraspinatus, infraspinatus, teres minor, subscapularis). Release immediately upon tap.
The Kimura from Crucifix exploits the defining advantage of crucifix position: complete bilateral arm control that eliminates the defender’s primary escape mechanism. With one arm trapped in your leg triangle and the other isolated by your hands, the figure-four grip on the free arm encounters virtually no resistance from typical Kimura defenses such as clasping hands, gripping the belt, or framing against the shoulder. The attack represents a natural secondary threat after choke attempts are defended, creating a seamless attack chain where chin defense directly exposes the arm to shoulder lock finishing mechanics.

Key Attacking Principles
What are the key principles for executing Kimura from Crucifix?
- Maintain crucifix leg triangle control throughout the entire Kimura attack—the trapped arm is your primary positional anchor that makes this finish viable
- Secure the figure-four grip on the free arm before committing to rotation—premature rotation without proper grip depth leads to grip slippage and escape
- Pin the opponent’s elbow tight to your torso before applying rotational pressure to maximize mechanical advantage and eliminate the hitchhiker escape
- Apply rotation slowly and progressively behind the opponent’s back, treating the shoulder joint as a hinge requiring controlled angular displacement
- Use your body weight and hip position to reinforce the rotational force rather than relying on arm strength alone for the finish
- Transition between choke threats and Kimura seamlessly—when the opponent defends the neck, the arm becomes exposed, creating a forced-choice dilemma
Prerequisites
What do you need before attempting Kimura from Crucifix?
- Established crucifix position with one arm securely trapped in your leg triangle and constant inward squeeze maintained throughout
- Control of the opponent’s free arm through wrist grip or overhook—this arm becomes the Kimura target
- Opponent positioned on their side or back with limited hip mobility preventing explosive escape movements
- Your upper body positioned close to the opponent’s head and shoulders providing weight pressure and direct submission access
- Opponent’s choke defense (chin tuck or hand fighting) has redirected your attack from neck to the exposed arm
Execution Steps
How do you execute Kimura from Crucifix step by step?
- Consolidate crucifix control: Ensure your leg triangle is locked tight around the opponent’s near arm with constant inward squeeze. Your chest presses into their upper back, and your hips are positioned perpendicular to their torso for maximum stability and control. (Timing: 0-3 seconds)
- Isolate the target arm: Identify the free arm controlled by your hands. Transition from a basic wrist grip to controlling the arm at the wrist and forearm. Pull the arm slightly away from the opponent’s body to create the entry angle for the figure-four grip. (Timing: 2-4 seconds)
- Establish the figure-four grip: Thread your hand under the opponent’s wrist and forearm, reaching across to grip your own wrist in the classic Kimura figure-four configuration. Ensure the grip is deep with your palm controlling the back of their wrist for maximum rotational leverage. (Timing: 1-3 seconds)
- Pin the elbow to your body: Clamp the opponent’s elbow tight against your ribcage using your arms and body pressure. This eliminates the hitchhiker escape and creates a fixed fulcrum point around which the rotational force will be applied to the shoulder joint. (Timing: 1-2 seconds)
- Begin controlled rotation: Start rotating the opponent’s wrist behind their back using your figure-four grip while keeping the elbow pinned. Move slowly and progressively, painting their hand toward their opposite hip. Use your entire body to generate force rather than relying solely on arm strength. (Timing: 2-4 seconds)
- Apply progressive finishing pressure: Continue the rotation arc behind the opponent’s back while simultaneously lifting their elbow slightly away from their body. This combined rotational and lifting force attacks the shoulder’s range of motion from multiple angles, creating the tap-inducing pressure on the rotator cuff. (Timing: 1-3 seconds)
- Complete finish and release safely: If the opponent taps, immediately stop all rotational pressure and return the arm to neutral position by slowly reversing the rotation path. Release the figure-four grip completely. If they resist, maintain steady progressive pressure without jerking while monitoring for tap signals. (Timing: 1-2 seconds)

Opponent Defenses
How might your opponent defend against Kimura from Crucifix?
- Straightening the arm forcefully to prevent figure-four grip establishment (Effectiveness: Medium) - Your Response: Use both hands to bend the arm at the elbow by pushing on the wrist while pulling on the elbow crook, or transition to a straight armbar attack on the extended arm which becomes vulnerable when straightened from crucifix → Leads to Crucifix
- Rolling toward the Kimura side to relieve rotational pressure on the shoulder (Effectiveness: High) - Your Response: Follow the roll maintaining leg triangle and figure-four grip, adjusting your hip position to stay perpendicular. Use their rotational momentum to accelerate the Kimura rotation—the roll often works in your favor if you maintain both grips → Leads to Crucifix
- Explosive bridge and hip escape to create space and disrupt crucifix control (Effectiveness: Medium) - Your Response: Stay tight to their back and maintain the leg triangle squeeze. Use the bridge momentum to accelerate your Kimura rotation while they focus on movement rather than arm defense—their escape attempt becomes your finishing opportunity → Leads to Closed Guard
- Gripping own clothing, shorts, or belt to anchor the arm against rotation (Effectiveness: Low) - Your Response: Strip the grip by peeling fingers individually or apply steady rotational pressure which overwhelms their hand strength through sustained mechanical advantage. The single-hand grip cannot withstand figure-four leverage → Leads to Crucifix
