What is RNC Defense?

RNC Defense encompasses the systematic defensive framework for preventing, defending against, and escaping the rear naked choke from back control positions. This concept integrates multiple defensive layers including proactive hand fighting, chin protection mechanics, arm positioning strategies, and emergency escape protocols. The defensive hierarchy begins with preventing the choke from being locked in the first place through proper hand fighting and posture management, progresses through active defense once hands are in position, and culminates in last-resort escape mechanics when the choke is partially secured.

The concept operates on the principle that defense must be layered and progressive, with each defensive layer buying time for the next. Early prevention through hand fighting is significantly more effective than late-stage escape attempts when the choke is deep. Understanding the mechanical requirements for a successful RNC - namely the choking arm across the neck, the opposite hand securing behind the head, and proper body positioning - allows defenders to systematically deny each requirement. The concept emphasizes that defending the neck is the absolute priority from back control, superseding all other positional considerations.

RNC Defense represents one of the most critical survival skills in BJJ, as failure to defend this submission can result in unconsciousness within seconds once properly applied. The concept requires developing specific tactile sensitivity to recognize when the attacker’s hands are approaching the neck, reflexive hand positioning to block choking attempts, and the mental composure to execute defensive sequences under extreme pressure and oxygen deprivation. Mastery involves not just knowing the techniques, but developing the automatic responses and panic control necessary to execute them when partially choked.

Core Components

• Hand fighting must begin before the choke is attempted - proactive defense is exponentially more effective than reactive defense
• Protect the neck first, escape the position second - positional hierarchy is irrelevant if you are unconscious
• The chin is your first line of defense - tuck it to deny neck access and create structural barriers
• Two-on-one hand control defeats one arm - focus defensive efforts on controlling the choking arm before it crosses
• Create space between your neck and their choking arm through constant movement and frame creation
• Address the lock before addressing the squeeze - if hands are locked, break the grip before attempting to remove the arm
• Emergency escapes require immediate explosive action - hesitation when partially choked leads to unconsciousness
• Breathing control and mental composure are as important as technical defense - panic accelerates the choke’s effectiveness
• The non-choking arm is equally important - it secures the position and prevents your defensive hand movement

Component Skills

Proactive Hand Fighting: The ability to recognize and intercept choking attempts before the arm crosses the neck. This involves maintaining constant hand awareness near the neck area, using two-on-one grips to control the choking arm, and creating frames that prevent the attacker’s hands from getting into position. Skilled practitioners develop tactile sensitivity to feel when hands are approaching the neck and reflexively engage defensive hand fighting without visual confirmation.

Chin Tucking Mechanics: The technical execution of chin protection that creates structural barriers without exposing the jaw to strikes or pain compliance. This involves tucking the chin into the chest while maintaining the ability to breathe, using the chin to block arm insertion while the hands work to clear the threat, and understanding when to sacrifice the chin position for more effective hand-based defenses. The skill includes knowing when chin protection alone is sufficient versus when it must be combined with other defensive layers.

Grip Breaking Under Pressure: The specific techniques for breaking the attacker’s hand clasp once their hands have connected behind your head or neck. This requires understanding the mechanical weaknesses of various grip configurations (gable grip, palm-to-palm, figure-four), the proper angle and leverage for breaking each grip type, and the ability to generate explosive force despite being compressed from back control. Advanced practitioners can break grips while simultaneously creating escape angles.

Shoulder Positioning and Rotation: The use of shoulder alignment and rotation to create gaps between the neck and choking arm, making it difficult for the attacker to achieve proper choking depth. This involves lifting the shoulder on the choking arm side to create space, rotating the body to maintain this space, and using shoulder frames to prevent the attacker from achieving flat back control. The skill extends to recognizing which shoulder movements create space versus which invite deeper chokes.

Arm Extraction Sequences: The systematic methods for removing the choking arm from across the neck once it has been inserted but before the choke is fully locked. This includes peeling techniques using both hands, creating rotational movement that loosens the arm’s position, and transitioning defensive hand positions from blocking to extracting. The sequences must be executed with proper timing and explosive power to overcome the attacker’s strength advantage from back control.

Emergency Escape Mechanics: The last-resort defensive actions when the choke is deep and consciousness is fading. This encompasses explosive back escape attempts, sacrificial positional movements that trade inferior positions for neck freedom, and the specific sequence of clearing the choking arm then the supporting arm. These mechanics require maximum effort execution and acceptance of positional damage in exchange for survival.

Breathing Management Under Duress: The physiological and psychological control required to maintain effective breathing patterns while being attacked from back control and during partial choking attempts. This includes taking deep breaths during defensive moments, avoiding panic-induced hyperventilation, and maintaining the mental clarity necessary to execute technical defenses even when oxygen-deprived. Advanced skill involves recognizing the difference between air restriction (trachea compression) and blood restriction (carotid compression) and adjusting breathing accordingly.

Tactical Recognition and Priority Management: The decision-making framework for determining which defensive layer to employ based on the current threat level and arm positioning. This involves instantly assessing whether to prioritize hand fighting, grip breaking, or emergency escape based on how deep the attack has progressed. The skill includes recognizing when to abandon positional escape attempts in favor of pure defensive survival, and conversely when the choke threat is minimal enough to pursue positional improvement simultaneously.

Related Principles

• Chin Protection (Prerequisite): Chin protection serves as the foundational defensive layer that RNC Defense builds upon. Understanding proper chin positioning and structural frames created by the jawline is essential before developing more advanced hand fighting and escape sequences.
• Hand Fighting from Back (Complementary): Hand fighting from back control is the primary proactive component of RNC Defense. The two concepts work in tandem, with hand fighting preventing the choke from being attempted while RNC Defense addresses situations where hand fighting has been bypassed or defeated.
• Defensive Strategy (Extension): RNC Defense applies the broader principles of defensive strategy specifically to the rear naked choke threat. It exemplifies the defensive hierarchy of prevention, active defense, and emergency escape that applies across all submission defense scenarios.
• Escape Fundamentals (Complementary): RNC Defense integrates with general escape fundamentals by applying core escape principles (creating space, hip movement, explosive action) specifically to the context of defending chokes from back control. The concepts reinforce each other in developing comprehensive defensive skills.
• Submission Defense Concepts (Prerequisite): General submission defense concepts provide the theoretical foundation that RNC Defense applies to the specific context of rear naked choke attacks. Understanding submission mechanics, defensive timing, and threat recognition are prerequisites for effective RNC-specific defense.
• Back Escape Series (Complementary): Back escape sequences and RNC Defense must be coordinated, as positional escape attempts can create vulnerabilities to choking attacks while defending the neck can limit escape options. Advanced practitioners integrate both concepts fluidly, defending submissions while simultaneously working toward positional improvement.
• Frame Creation (Complementary): Frame creation principles apply directly to RNC Defense through the use of shoulder frames, chin frames, and hand positioning to create structural barriers against the choking arm. Effective framing buys time for more active defensive measures.
• Space Creation (Complementary): Space creation between the neck and choking arm is a critical component of RNC Defense. The general principles of creating and maintaining space under pressure apply directly to defending the rear naked choke from back control positions.
• Energy Conservation (Complementary): Energy conservation is essential in RNC Defense as panic-driven responses rapidly deplete energy reserves. Understanding when to expend maximum energy versus when to use technical efficiency allows defenders to maintain defensive capacity throughout extended back control scenarios.
• Grip Breaking (Extension): RNC Defense applies general grip breaking principles to the specific context of breaking the attacker’s hand clasp behind the head. Understanding leverage, mechanical weakness of grips, and explosive application of force are prerequisite skills for effective RNC Defense.
• Defensive Framing (Complementary): Defensive framing concepts provide the structural foundation for RNC Defense, particularly in using the chin, shoulders, and hands to create barriers against the choking arm. Proper frame maintenance prevents deep choke establishment.
• Hip Escape Mechanics (Complementary): Hip escape mechanics integrate with RNC Defense when creating angles and space to facilitate arm removal and positional improvement. However, practitioners must balance hip escape attempts with maintaining neck protection throughout the movement.

Application Contexts

Back Control: The primary application context where RNC Defense is essential for survival. All defensive layers from proactive hand fighting to emergency escapes are directly applicable. The defender must maintain constant neck protection while working toward positional escape, creating the fundamental tension between defensive and offensive priorities that defines back control defense.

Seat Belt Control Back: When the attacker has established the seatbelt grip configuration, RNC Defense focuses on controlling the choking-side arm before it can transition to the neck. Hand fighting targets the arm that will cross the neck, while secondary attention monitors the arm behind the back. The asymmetric grip creates specific vulnerabilities and defensive opportunities that skilled defenders exploit.

Body Triangle: The body triangle eliminates lower body escape options, making neck defense even more critical as positional escape is severely limited. RNC Defense becomes the primary defensive focus, with all energy directed toward preventing and defending choking attempts rather than escaping the position. The compression from the body triangle also affects breathing, requiring adjusted breathing management strategies.

Standing Back Control: Standing back control presents modified RNC Defense challenges due to different base and balance requirements. The defender can use gravity and dropping movements to create space, but must also maintain balance while defending. The standing context allows for different escape angles and emergency movements not available from grounded back control.

Crucifix: From crucifix, RNC Defense principles apply to defending various choke attacks including rear naked choke variations. The arm entrapment of crucifix limits defensive hand options, requiring emphasis on chin protection, neck positioning, and the use of the free arm for maximum defensive effectiveness. Emergency escapes often involve sacrificing positional control entirely to free trapped arms.

Turtle: When defending turtle position, RNC Defense concepts apply proactively to prevent the attacker from establishing back control with hands in choking position. This involves protecting the neck during the transition from turtle to back control, fighting hands before they can establish dangerous grips, and understanding that defending chokes from turtle is easier than from established back control.

High Mount: While less common, RNC threats can emerge from high mount positions when the attacker transitions toward the head. RNC Defense concepts of hand fighting and neck protection apply during these transitional moments, preventing the attacker from securing back-control-like choking positions from mount variations.

Side Control: RNC Defense principles apply when the top player is attempting to transition to back control or when attempting certain choke attacks from side control variations. The defender uses hand fighting and neck protection concepts to prevent the establishment of choking positions during the transition phase, when defensive action is most effective.

North-South: From north-south position, RNC Defense concepts adapt to defending against choke attacks that target the neck from different angles. While not traditional RNC attacks, the defensive principles of hand fighting, neck protection, and grip breaking apply to various choke threats from this position.

Defensive Position: When in defensive shell or fetal positions during scrambles, RNC Defense concepts guide neck protection priorities. The defender maintains awareness of neck exposure even while defending other attacks, ensuring that defensive postures don’t inadvertently create choking opportunities.

Guard Recovery: During guard recovery attempts from inferior positions, RNC Defense principles prevent the opponent from capitalizing on exposed neck positions during the transition. The defender maintains neck awareness and hand positioning even while executing complex recovery movements.

Standing up in Base: When executing technical standup from bottom positions, RNC Defense concepts guide the protection of the neck during the vulnerable standing transition. The defender must maintain hand awareness and neck protection while changing levels and establishing base, preventing opponents from capitalizing on the transitional vulnerability.

Harness: The harness grip configuration is a direct precursor to rear naked choke attempts. RNC Defense in this context focuses on preventing the transition from harness to choking position, controlling the opponent’s hands before they can adjust to neck attacks, and maintaining defensive awareness throughout.

Gift Wrap: Gift wrap positions create unique RNC Defense challenges as one arm is trapped. The defender must maximize the effectiveness of the free arm while using chin protection and body positioning to compensate for the trapped arm. Priority shifts to preventing the second hand from establishing the choke.

Rear Triangle: When caught in rear triangle positions, RNC Defense principles apply to defending combination attacks where triangle control sets up rear naked choke attempts. The defender must address both the triangle pressure and the neck attack simultaneously, often prioritizing neck defense when both threats are present.

Decision Framework

1. Assess immediate threat level - are the attacker’s hands currently near your neck or already in choking position?: If hands are not yet near neck: Implement proactive hand fighting to prevent initial approach. If one hand is approaching: Focus two-on-one control on the approaching arm. If both hands are in position or one arm is across neck: Escalate to active defense and grip breaking protocols.
2. Evaluate current chin position and neck accessibility - is your chin protecting the neck or is it exposed?: If chin is up or neck exposed: Immediately tuck chin to chest to create structural barrier. If chin is already protected: Maintain position while hands work to address arm threats. If choking arm is under chin: Use chin to trap arm while working hand-based defenses to clear it before opponent can adjust.
3. Determine which defensive hand position provides maximum protection based on current arm configuration.: If choking arm is approaching but not across: Use both hands to grip and control the wrist/forearm, preventing it from crossing neck. If arm is partially across: Use near-side hand to grip the wrist while far-side hand blocks the opposite hand from connecting. If hands are connected: Focus both hands on breaking the grip at its weakest point.
4. Assess whether you can breathe effectively - is the choke affecting air or blood flow?: If breathing is unrestricted: Continue systematic technical defense while conserving energy. If air is partially restricted: Increase urgency but maintain technical precision. If blood flow is being restricted (feeling light-headed): Immediately escalate to emergency explosive escape procedures regardless of positional cost.
5. Evaluate whether grip breaking or arm removal is the current priority based on hand connection status.: If hands are locked together: Use both hands with maximum explosive force to break the grip at the weakest point (typically between fingers or at the wrist connection). If hands are not yet locked: Prevent the connection by controlling one or both arms. If grip is broken: Immediately work to remove choking arm from neck before opponent can re-establish.
6. Determine if shoulder positioning can create additional space and defensive leverage.: If choking-side shoulder is flat: Lift shoulder toward ear to create gap between neck and arm. If shoulder is elevated: Maintain elevation while rotating body to expand the gap. If rotation is creating space: Combine with hand-based defenses to remove arm from neck entirely.
7. Assess whether you’re making defensive progress or if the situation is deteriorating.: If defenses are working and pressure is decreasing: Continue current defensive sequence while looking for opportunities to improve position. If defenses are failing and choke is tightening: Abandon current approach and attempt alternative defensive layers. If consciousness is fading: Execute emergency explosive escape immediately, accepting any positional consequence to clear the choke.
8. Once immediate choking threat is neutralized, determine whether to continue defensive mode or transition to escape.: If choke is fully cleared and opponent’s hands are away from neck: Transition focus from pure defense to positional escape while maintaining neck awareness. If choke is only partially cleared: Maintain primary focus on defense until threat is completely neutralized. If opponent is resetting for another choke attempt: Return to step 1 and implement proactive hand fighting protocols.

Common Mistakes

• Mistake: Focusing on positional escape before adequately defending the immediate choking threat
  • Consequence: The practitioner expends energy on hip escapes or back escapes while the opponent secures the choke, resulting in being submitted during the escape attempt. The fundamental error is prioritizing positional improvement over survival.
  • Correction: Establish the absolute rule: defend the neck first, escape the position second. Only begin positional escape attempts once the immediate choking threat is fully neutralized and controlled. Accept that you may remain in back control longer, but you will remain conscious.
• Mistake: Using only one hand to defend against the choking arm while the other hand is passive or pushing the opponent
  • Consequence: The single defending hand is typically overpowered by the choking arm, especially once the opponent has mechanical advantage with the arm across the neck. One-handed defense is almost always insufficient against a committed choking attempt.
  • Correction: Commit both hands to defending the choking arm using two-on-one control. Release ineffective pushing or framing attempts and prioritize neck defense. Only use one hand defensively if the other hand is performing a specific critical function like preventing the second hand from connecting.
• Mistake: Attempting to pull the choking arm away from the neck using bicep strength alone
  • Consequence: This creates a pure strength battle that strongly favors the attacker, who has superior leverage with the arm across the neck and body weight compressing from behind. The defender exhausts their arm strength rapidly while making minimal progress.
  • Correction: Use proper leverage mechanics: grip the wrist with both hands, create angles by rotating the body, use whole-body movement rather than isolated arm strength, and attack the grip connection rather than trying to pull the entire arm away. Technique and leverage must supplement raw strength.
• Mistake: Keeping the chin elevated or looking up during the defensive sequence
  • Consequence: An elevated chin creates a clear opening for the choking arm to slide deeply under the jaw, eliminating a critical defensive layer and allowing the opponent to establish the choke more quickly. Visual orientation upward provides no defensive benefit.
  • Correction: Maintain chin tucked to chest throughout the defensive sequence unless tactically lifting it for a specific technique. Develop the ability to defend effectively without visual confirmation, relying on tactile awareness instead. Accept that you cannot always see what you’re defending against.
• Mistake: Panic breathing or holding breath when the choke is being attempted
  • Consequence: Hyperventilation rapidly depletes oxygen reserves and accelerates the onset of fatigue and panic. Breath holding creates artificial oxygen deprivation that compounds the effects of any actual choking pressure. Both patterns severely compromise defensive effectiveness.
  • Correction: Practice controlled breathing patterns during RNC defense drills, consciously taking slow deep breaths during defensive moments and avoiding breath holding. Train the physiological and psychological response to remain calm under choking pressure. Recognize that panic is more dangerous than the actual technique in many cases.
• Mistake: Waiting too long to implement emergency explosive escapes when the choke is deep
  • Consequence: Hesitation when consciousness is fading leads to unconsciousness before the escape can be executed. The window for emergency escapes is extremely narrow - typically 2-3 seconds once blood flow is fully restricted. Late execution equals failure.
  • Correction: Develop recognition of the point of no return where technical defense has failed and emergency action is required. Practice explosive escape sequences until they become reflexive. Accept that emergency escapes will damage your position but preserve consciousness. Better to be in mount bottom than unconscious in back control.
• Mistake: Ignoring the non-choking hand and allowing it to connect behind the head unopposed
  • Consequence: Once both hands are connected, the mechanical strength of the choke increases exponentially and the difficulty of defense rises dramatically. Allowing the second hand to easily find its position essentially gives the opponent a completed choke setup.
  • Correction: Divide defensive attention between preventing the choking arm from crossing and preventing the second hand from connecting. Use one hand to control the choking wrist while the other hand blocks or redirects the second hand. Understand that preventing the connection is vastly easier than breaking an established grip.
• Mistake: Attempting the same failed defensive technique repeatedly without adjusting approach
  • Consequence: If a defensive technique isn’t working after the first sincere attempt, continuing the same action wastes precious time and energy while the choke tightens. This represents both tactical inflexibility and failure to recognize when to change strategies.
  • Correction: Develop a hierarchy of defensive attempts: if the first layer fails within 2-3 seconds, immediately progress to the next defensive option. Move from hand fighting to grip breaking to arm removal to emergency escape in a progressive sequence. Never commit more than a few seconds to a technique that isn’t producing results.

Training Methods

Progressive Resistance RNC Defense Drilling (Focus: Developing automatic defensive responses calibrated to the current threat level, building muscle memory for each defensive layer, and creating smooth transitions between defensive techniques as the situation deteriorates or improves.) Partner drill where the defender practices the complete defensive sequence against incrementally increasing resistance. Begin with the attacker slowly approaching with hands toward the neck, allowing the defender to implement proactive hand fighting. Progress through stages of increasing speed and resistance: arm approaching, arm crossing, one hand connecting, grip established, and partial squeeze. The defender practices the appropriate defensive layer for each stage, developing the recognition and response patterns for different threat levels.

Positional Sparring from Back Control with Survival Priority (Focus: Building defensive endurance, testing defensive techniques against fully resisting opponents, developing the mental composure to defend under sustained pressure, and identifying which defensive techniques work reliably in live situations versus which fail under pressure.) Live training from back control bottom position where the defender’s primary objective is to avoid being choked for a set time period (3-5 minutes) rather than to escape the position. The attacker has full permission to attempt chokes while the defender focuses exclusively on implementing RNC Defense concepts. This isolates the defensive skill from the positional escape skill, allowing focused development of neck defense under realistic pressure.

Grip Breaking Specific Training (Focus: Developing maximal explosive power for grip breaking, understanding the mechanical weaknesses of each grip type, building grip-specific breaking techniques, and creating the confidence that grips can be broken even when very tight.) Isolated drill focusing exclusively on breaking various hand grip configurations once they are established behind the head. Partner establishes different grips (gable grip, palm-to-palm, figure-four, wrist-over-wrist) with varying degrees of tightness, and the defender practices the specific breaking mechanics for each. Include variations with body position (flat back control, side-to-side, sitting up) to practice breaking grips from different angles and contexts.

Scenario-Based Emergency Escape Training (Focus: Building the explosive power and technique required for last-resort escapes, developing the mental threshold for recognizing when emergency action is required, practicing the acceptance of positional sacrifice for survival, and conditioning the panic response to remain functional even under extreme pressure.) Training methodology where the partner establishes various degrees of choke tightness and the defender practices emergency explosive escape sequences. Include scenarios ranging from arm just crossing the neck to partially tight chokes (stopping before any actual danger). The defender practices the full emergency sequence: explosive bridge, hip escape, arm clearing, and positional sacrifice movements. Critically, include mental preparation for executing these techniques under oxygen deprivation and panic.

Flow Rolling with RNC Defense Emphasis (Focus: Integrating RNC Defense with general movement and position transitions, developing awareness of when neck threats are emerging, practicing the balance between defensive and offensive priorities during back control scenarios, and building the habit of automatic neck protection across all rolling contexts.) Moderate-resistance rolling where both partners flow between positions, with specific emphasis on the defender implementing RNC Defense concepts whenever back control positions emerge. The attacker provides realistic but not maximum resistance, allowing the defender to practice defensive sequences in a dynamic context without the full stress of competition-level sparring. The goal is to develop fluid application of defensive concepts across position transitions.

Instructional Role Reversal and Teaching (Focus: Deepening conceptual understanding through teaching, identifying gaps in personal knowledge through the requirement to explain techniques clearly, developing coaching and correction skills, and reinforcing proper technique through demonstration and repetition.) Training approach where practitioners take turns teaching RNC Defense concepts to less experienced partners, explaining the mechanics, demonstrating the techniques, and coaching the partner through the execution. The teaching process requires deep understanding of the concepts and reveals gaps in knowledge through the attempt to articulate and demonstrate techniques clearly.

Expert Insights

• John Danaher: The rear naked choke represents one of the highest percentage submissions in all of grappling precisely because of the mechanical advantages it provides the attacker and the limited defensive options available once properly applied. Understanding RNC Defense requires first understanding the mechanical requirements for a successful choke: the arm must cross deeply under the chin or across the neck, the opposite hand must connect to secure the position, and the attacker’s body position must create forward pressure that prevents the defender from creating space. Your defensive strategy must systematically deny these requirements in reverse order of difficulty - it is far easier to prevent the initial arm crossing than to escape once the choke is locked. The concept of defensive layering is critical here: your first layer is proactive hand fighting before any arm approaches the neck, your second layer is chin protection and hand blocking as the arm approaches, your third layer is grip breaking if hands connect, and your final layer is emergency explosive escape if the choke becomes tight. Each layer buys time for the next, and mastery involves recognizing which layer you’re currently in and applying the appropriate defensive response. Most practitioners fail because they skip defensive layers, attempting emergency escapes when proactive defense would work, or continuing technical defense when emergency action is required. The key to effective defense is calibrating your response to the current threat level.
• Gordon Ryan: In competition, the rear naked choke is the submission I’ve both finished most often and had to defend most often at the highest levels. The reality is that against elite-level opponents, if you let them fully establish back control with hands in choking position, you’re already in serious trouble. My RNC Defense strategy prioritizes preventing the setup over defending the finish - I focus intensely on hand fighting and controlling my opponent’s arms before they can even attempt to go for the neck. The specific detail that changed my defensive game was understanding that you need to commit both hands to defending the choking arm once it starts crossing. I see so many people try to defend with one hand while pushing with the other, and it just doesn’t work against high-level opposition. They’re stronger with one arm across your neck than you are with one arm trying to stop them. My approach is simple: as soon as I feel a hand coming toward my neck, both my hands go to that wrist and I fight like my life depends on it, because in competition, my consciousness certainly does. The other key detail is maintaining offensive pressure even while defending - I’m always looking to improve my position while defending the neck, never purely defensive. If I can create angles or start working back to guard while defending the choke, I’m forcing my opponent to make decisions between maintaining the choking attack and preventing my positional improvement. The worst thing you can do is become purely defensive and give them all the time in the world to perfect the choke.
• Eddie Bravo: RNC Defense from a 10th Planet perspective has some unique elements because of how we use the position and how we defend it. First, we spend a lot of time working from back control both attacking and defending, so we’re very familiar with the angles and timing. One thing I emphasize that’s different from traditional approaches is using the Lockdown and body positioning concepts even from bottom back control - creating angles with your hips and legs to make it harder for them to get flat on your back, which is when the choke is most dangerous. We also work a lot on what I call ‘offensive defense’ where you’re immediately looking for your own attacks even while defending the neck. If I’m defending a choke, I’m simultaneously looking to attack their arms for kimuras or to spin into them for reversal opportunities. This creates dilemmas where they have to choose between finishing the choke and defending your attacks, which often opens up escape routes. Another innovation we use is practicing defense while already partially choked - sounds crazy, but we train the ability to function and execute technique even when you’re getting squeezed, because in real competition situations, you’re often going to be defending while under partial pressure. You need to be able to think and move effectively even when you’re feeling that pressure, not just when you’re comfortable. We also emphasize the mental game aspect - staying calm, breathing controlled, not panicking. Panic kills more people in RNC situations than the actual technique. Train your mind to stay ice cold even when your neck is being attacked.
