The Knee Bar from Top Positions represents a modern submission-oriented approach to passing where the practitioner transitions directly from passing scenarios to leg entanglement attacks while maintaining superior position. This technique bridges traditional positional advancement with contemporary leg lock systems, creating immediate submission threats during the passing process itself. The fundamental concept involves recognizing opportunities during leg drag sequences, headquarters positions, or knee slice attempts where the opponent’s leg becomes isolated and vulnerable to kneebar attack. By maintaining top position throughout the attack, the practitioner combines the safety of positional dominance with the finishing power of leg entanglements, creating a low-risk, high-reward attacking scenario. The technique has become increasingly prevalent in modern no-gi competition where leg locks are legal at all skill levels, though it requires careful application in gi competition due to varying ruleset restrictions. Understanding the biomechanics of knee hyperextension, proper control mechanics to prevent escapes, and systematic finishing details transforms this from an opportunistic attack into a reliable component of a comprehensive passing and submission system.

Key Principles
- Maintain superior top position and base throughout the attack to prevent sweeps or reversals while threatening submission
- Isolate opponent’s leg through passing mechanics before transitioning to submission control, ensuring positional security first
- Control opponent’s ankle securely in armpit with elbow connection to ribs, creating structural integrity for submission pressure
- Position hips close to opponent’s knee joint to maximize leverage and create efficient pressure transmission for hyperextension
- Apply progressive pressure gradually over multiple seconds, never explosively, to ensure partner safety and tap recognition
- Control opponent’s free leg or upper body with opposite hand to eliminate defensive frames and prevent escape pathways
- Maintain wide base with posting leg to preserve balance and prevent opponent from using their free leg to create sweeping angles
Prerequisites
- Top position established with opponent on bottom, typically during passing sequence or guard engagement
- One opponent leg isolated through passing mechanics such as leg drag, knee slice, or headquarters control
- Secure grip or control on opponent’s ankle or lower leg area with ability to transition to armpit control
- Hip positioning allowing proximity to opponent’s knee joint for leverage application during finishing sequence
- Base and balance maintained with free leg posted to prevent sweeps while executing leg attack transition
- Opponent’s defensive structure compromised through passing pressure, reducing their ability to establish effective frames or counter-grips
Execution Steps
- Isolate opponent’s leg during passing: From passing position such as headquarters, leg drag, or knee slice, control opponent’s leg by gripping ankle or lower leg while maintaining chest pressure and top position. Prevent opponent from establishing defensive frames with their hands by controlling distance and applying forward pressure with your upper body. (Timing: Execute during opponent’s defensive adjustment when their leg is extended or isolated)
- Transition ankle to armpit control: Bring opponent’s ankle to your armpit while maintaining tight elbow connection to your ribs, creating a structural seal that prevents rotation or extraction. Keep your grip on their lower leg or foot as you establish this armpit control, ensuring continuous connection throughout the transition. (Timing: Move smoothly and continuously to prevent opponent from retracting leg)
- Position hips near opponent’s knee joint: Adjust your hip position to place your hip bone directly adjacent to opponent’s knee joint, creating the fulcrum point for hyperextension leverage. Your torso should be perpendicular or angled relative to opponent’s body, with your hips forming the pressure point against their knee. (Timing: Establish before applying any extension pressure)
- Control opponent’s free leg and upper body: Use your free hand to grip opponent’s far ankle, knee, or pants to prevent them from pushing your head or creating hooks for sweeps. Alternatively, maintain chest or shoulder pressure on their upper body to limit mobility and defensive options. Your base leg should be posted wide for stability. (Timing: Maintain throughout entire attack sequence)
- Break opponent’s defensive grips: If opponent has established grips on their own leg or on your body to maintain defensive structure, systematically strip these grips by hand fighting or by adjusting your body position to make their grips mechanically ineffective. Ensure their leg is fully isolated before proceeding to finish. (Timing: Complete before applying finishing pressure)
- Apply progressive extension pressure: Extend your hips forward and slightly upward while maintaining tight armpit control on opponent’s ankle, creating hyperextension pressure on their knee joint. Apply pressure gradually over 3-5 seconds minimum, watching opponent’s face and listening for tap signal. Keep elbow tight to ribs throughout to prevent ankle rotation or escape. (Timing: Smooth and controlled application, never explosive or sudden)
- Maintain control or transition on defense: If opponent successfully defends by creating space, turning their knee, or establishing effective frames, maintain control and transition to alternative attacks such as heel hook, saddle position, or complete the pass to mount or side control rather than abandoning position entirely. (Timing: Immediate recognition of defensive success triggers transition)
Opponent Counters
- Opponent pulls knee toward chest and establishes defensive frames with hands on your hips or shoulders (Effectiveness: High) - Your Response: Transition to mount or side control by following their defensive movement, or strip their frames and re-establish kneebar control with better hip positioning
- Opponent turns knee inward toward floor to relieve hyperextension pressure and potentially expose their back (Effectiveness: Medium) - Your Response: Follow their rotation and transition to truck position or saddle entry, or switch to heel hook attack as their defensive turn exposes the heel
- Opponent uses free leg to push your head or shoulder, creating space and disrupting your base (Effectiveness: High) - Your Response: Control opponent’s free leg with your free hand at ankle or knee before they can establish effective push, or adjust angle to reduce effectiveness of their frame
- Opponent performs explosive hip escape to extract their trapped leg from your control (Effectiveness: Medium) - Your Response: Follow their hip movement while maintaining armpit control on ankle, adjusting your hip position to stay connected to their knee joint throughout their escape attempt
- Opponent establishes grip on their own leg or ankle, creating defensive structure that prevents full extension (Effectiveness: Medium) - Your Response: Strip opponent’s grip through hand fighting or by adjusting your angle to make their grip mechanically ineffective, or transition to alternative leg attack or passing position
Test Your Knowledge
Q1: What is the most critical mechanical principle for generating effective hyperextension pressure during kneebar from top positions? A: The most critical mechanical principle is positioning your hips directly adjacent to the opponent’s knee joint to create an effective fulcrum point. Your hip bone must remain tight against their knee throughout the attack, allowing any extension of your hips to translate directly into hyperextension pressure on their knee joint. If your hips are positioned too far from their knee, the leverage is dramatically reduced and the submission becomes ineffective despite appearing properly set up. This hip-to-knee connection must be maintained even as the opponent moves, requiring you to follow their defensive movements while preserving this critical distance relationship.
Q2: Why is controlling the opponent’s free leg or upper body essential for successful kneebar attacks from top positions? A: Controlling the opponent’s free leg or upper body is essential because without this secondary control, they can use their free leg to create powerful frames against your head or shoulders that disrupt your base and potentially sweep you. The free leg represents their primary defensive tool for creating distance, establishing hooks for reversals, or generating angles that compromise your top position. By controlling their free leg at the ankle or knee with your free hand, or maintaining chest pressure on their upper body, you eliminate these defensive pathways and ensure they cannot use their mobility to escape the submission or reverse position. This secondary control transforms the kneebar from a risky attack into a dominant controlling position.
Q3: What is the proper progressive application timeline for kneebar pressure to ensure training partner safety? A: Kneebar pressure must be applied gradually and progressively over a minimum of 3-5 seconds, never explosively or suddenly. This timeline allows your training partner to recognize the danger, assess whether they can defend, and make the decision to tap before structural damage occurs to their knee ligaments. Throughout the application, you must watch your partner’s face and listen for tap signals, being prepared to release immediately. Explosive or sudden application can cause serious knee injuries before the partner can react, creating an unsafe training environment. The gradual application also allows you to develop better sensitivity to submission mechanics and tap recognition, making you a safer and more effective training partner.
Q4: How should you respond when your opponent defends the kneebar by turning their knee inward toward the mat? A: When the opponent turns their knee inward to relieve kneebar pressure, you should recognize this as an opportunity to transition to heel hook or truck position rather than forcing the kneebar finish. As they turn their knee, they necessarily expose their heel for heel hook attacks, or they may expose their back for truck entry. Immediately adjust your grip from their ankle to their heel area and establish heel hook control, or follow their rotation to establish truck position. This creates a submission chain where their defensive response to one attack directly opens another, forcing them into an unsolvable dilemma. Maintaining your control and following their movement is essential—never abandon position simply because the initial attack was defended.
Q5: What are the key differences between kneebar from top positions versus traditional ashi garami kneebar attacks? A: The key difference is that kneebar from top positions prioritizes maintaining superior positional control throughout the attack, while traditional ashi garami approaches may involve being on bottom or accepting more neutral positions. From top positions, you maintain your base, chest pressure, and positional dominance, reducing risk of sweeps or reversals while attacking. You use passing mechanics to isolate the leg rather than guard pulling or leg entanglement entries. The top position variation also typically involves different control mechanics, with emphasis on using your free hand to control their free leg or upper body, whereas ashi garami relies more heavily on leg-to-leg control. The strategic advantage is combining submission threat with positional safety, making it lower risk while maintaining finishing potential.
Q6: Why is it important to break the opponent’s defensive grips and frames before applying finishing pressure in kneebar from top positions? A: Breaking defensive grips and frames before applying finishing pressure is critical because these defensive structures prevent full leg isolation and provide the opponent with mechanical advantages that make the submission ineffective. When the opponent maintains grips on their own leg, they can control the positioning of their knee and prevent full extension. When they establish frames against your body with their hands, they create distance that reduces your leverage and provides platforms for escape. Attempting to finish the kneebar while these defensive structures remain in place typically results in failed submission attempts and wasted energy. The systematic approach—first breaking grips, eliminating frames, establishing complete control, and only then applying finishing pressure—dramatically increases success rates and makes the submission feel inevitable once proper control is achieved.
Safety Considerations
Kneebar from top positions requires careful attention to safety protocols due to the structural vulnerability of the knee joint to hyperextension injuries. Always apply pressure gradually over minimum 3-5 seconds rather than explosively, watching your partner’s face and listening for tap signals throughout. The knee joint can suffer serious ligament damage including ACL, PCL, and meniscus tears if pressure is applied too quickly or if taps are ignored. When training, both partners must communicate clearly about pressure levels and defensive capabilities. The attacking practitioner should never force the submission through defensive structures but rather maintain control and work systematically to establish proper finishing position. Partners should discuss their experience levels with leg locks before training this position, and beginners should work with experienced practitioners who understand proper application mechanics. In competition scenarios, be aware of ruleset restrictions—many gi competitions restrict or prohibit kneebars below brown belt. Always release immediately upon tap signal without any delay. Training should progress gradually through phases emphasizing control before finishing, and positional sparring should be conducted at appropriate intensity levels for participants’ skill levels.
Position Integration
The Knee Bar from Top Positions integrates seamlessly into modern BJJ systems by bridging traditional passing approaches with contemporary leg lock attacks, creating a submission-oriented passing game that combines positional safety with finishing potential. This technique fits within the broader guard passing framework as an alternative to traditional positional advancement, allowing practitioners to recognize when leg isolation during passing creates immediate submission opportunities rather than continuing to force positional passes against strong defenses. It connects to leg entanglement systems by providing entries to ashi garami variations, saddle positions, and heel hook attacks when initial kneebar attempts are defended. The position also integrates with back attack systems when opponents defend by turning their knee, exposing their back for truck entries. Strategically, this creates offensive dilemmas where opponents must simultaneously defend passing attempts and submission threats, dividing their defensive attention and creating openings in both domains. The technique is particularly valuable in no-gi competition where leg locks are universally legal, though it requires ruleset awareness in gi competition.
Expert Insights
- Danaher System: The kneebar from top positions represents one of the most strategically sound leg attacks in Brazilian Jiu-Jitsu because it combines the safety of positional dominance with the finishing power of leg entanglements, creating a low-risk, high-reward attacking scenario that intelligent competitors should prioritize. The fundamental principle that makes this position so effective is the maintenance of superior position throughout the attack—you never sacrifice your top position to hunt for the leg, rather you recognize when your passing mechanics naturally create leg isolation opportunities and transition seamlessly from passing to finishing. The critical mechanical detail that determines success or failure is the relationship between your hip position and your opponent’s knee joint. Your hips must function as a fulcrum point, positioned directly adjacent to their knee, so that any extension of your hips translates with mechanical efficiency into hyperextension pressure on their knee joint. When practitioners fail with this technique, it is almost always because they have positioned their hips too far from the opponent’s knee, dramatically reducing leverage despite appearing to have proper control otherwise. The systematic approach to this position involves a clear hierarchy of objectives: first establish and maintain top position, second isolate the leg through passing mechanics, third secure armpit control on the ankle with proper structural connection, fourth break any defensive grips or frames the opponent establishes, fifth position your hips as the fulcrum against their knee, and only sixth apply progressive extension pressure for the finish. This sequence ensures you never sacrifice positional security for submission attempts, paradoxically leading to higher finishing rates because you only attempt the submission when all prerequisites are satisfied. Furthermore, understanding this position as a node within a submission ecosystem rather than an isolated technique transforms its effectiveness—when opponents defend by turning their knee, they expose heel hook opportunities; when they defend by pulling their knee close, they expose mount or back attack opportunities; this systematic connectivity between positions creates unsolvable dilemmas that characterize high-level modern grappling.
- Gordon Ryan: The kneebar from top positions has become one of my highest percentage techniques in competition because it perfectly aligns with my strategic philosophy of maintaining dominant position while constantly threatening submissions. Unlike traditional ashi garami positions where you might be on bottom or in neutral positions, this variation keeps you on top throughout the entire attack, which is absolutely critical in competition scenarios where judges are scoring and referees might stand you up if things get stale. The way I integrate this into my game is primarily off passing sequences—when I’m working my leg drag or knee slice and opponents defend by framing or extending their leg to prevent the pass, I immediately recognize that as a kneebar opportunity rather than battling through the pass. This creates an offensive dilemma they fundamentally cannot solve: defend the pass and expose the leg, or defend the leg and get passed. My success rate with this technique improved dramatically when I stopped treating it as a separate attack and started viewing it as an integral part of my passing system. The specific mechanical detail that transformed my finishing rate was learning to control their far leg with my free hand throughout the attack—before I learned this, people would push my head or create hooks that disrupted my base, but once I started proactively controlling that far leg, the escapes disappeared. In my experience training and competing against the highest level grapplers in the world, the belly down variation is particularly effective because it removes defensive options—they can’t sit up, they can’t easily turn into you, and the angle makes it harder to defend. The competitive data strongly supports prioritizing this position: I’ve finished multiple ADCC and No-Gi Worlds matches with this technique, and my training data shows it has comparable finishing rates to rear naked choke when executed properly. One tactical insight that might not be obvious is that even when I don’t finish the kneebar, maintaining this control position puts tremendous psychological pressure on opponents while I remain relatively safe and offensive, often leading them to make defensive errors that open up other attacks or positional advancements.
- Eddie Bravo: The kneebar from top positions fits perfectly into the 10th Planet philosophy of attacking submissions without giving up position—we never want to sacrifice control to hunt for subs, we want to create situations where the submission attack enhances our positional control rather than compromising it. What’s beautiful about this technique is how it integrates with our passing system, particularly from headquarters where we’re controlling one leg and can either pass or attack depending on how they defend. The innovation I’ve brought to this position is connecting it to our truck system—when people defend the kneebar by turning their knee toward the mat, which is a pretty common defensive instinct, they’re actually loading themselves directly into truck position, which then opens up the twister, back attacks, or banana split. This creates a submission chain where every defensive option leads to another attack, embodying that dilemma-based approach that defines high-level no-gi grappling. Another variation we’ve developed in the 10th Planet system is hitting the kneebar during the transition from lockdown to old school sweep—when you’re coming up with the old school and they’re trying to defend by posting, there’s often a beautiful kneebar entry where you can catch their leg and immediately threaten the knee. One detail I emphasize that’s different from traditional approaches is being comfortable standing up into the kneebar when they create space—sometimes when they’re defending well from bottom and pushing your hips away, you can actually stand up while keeping that ankle control and drop your weight into the finish, which creates a completely unexpected angle that catches people off guard. The whole position exemplifies what we’re trying to do in 10th Planet: stay creative, stay offensive, create chains where defending one thing opens another, and never accept static positions. In training, we drill this heavily as part of our passing sequences because in no-gi especially, where leg locks are fair game at all levels, you need to be able to recognize these opportunities instantly and transition smoothly from passing to finishing without telegraphing your intentions.
