What is Lachlan Giles Leg Lock Defense Framework?
The Lachlan Giles Leg Lock Defense Framework represents one of the most comprehensive and scientifically-informed approaches to defending leg attacks in modern Brazilian Jiu-Jitsu. Developed through extensive competition experience at the highest levels including ADCC, this system emphasizes prevention over reaction, teaching practitioners to recognize and neutralize leg entanglement threats before they fully develop. The framework is built on understanding the mechanical hierarchy of leg lock positions, from least to most dangerous, and provides specific defensive protocols for each stage of entanglement. Rather than relying on strength or flexibility, Giles’ methodology focuses on proper positioning, hip alignment, and systematic counter-mechanics that work regardless of physical attributes. The system integrates seamlessly with modern guard retention principles while specifically addressing the unique challenges posed by contemporary leg lock specialists who build their entire games around the lower body.
Core Principles
- Prevention over escape - recognize entanglement patterns early and shut them down before full control is established
- Hierarchical understanding - know which positions are immediately dangerous versus those that allow time for systematic escape
- Hip alignment maintenance - keep hips square to opponent’s hips to prevent optimal finishing angles
- Inside position priority - control inside space to prevent cross-ashi and saddle entries
- Systematic clearing sequences - use specific step-by-step protocols rather than explosive scrambling
- Heel exposure awareness - understand when your heel is vulnerable versus protected by position
- Counter-entanglement as offense - turn defensive sequences into offensive leg attack opportunities
Key Components
Entanglement Prevention (Eliminate majority of leg lock threats before they develop into dangerous positions) The foundational layer of the system focuses on preventing leg entanglement before it occurs through proper distance management, foot positioning, and grip fighting specific to leg lock situations. This includes recognizing common entry patterns from standing, guard passing, and guard playing scenarios, then implementing specific defensive grips and frames that deny access to the legs while maintaining offensive capability.
Position Hierarchy Recognition (Assess risk accurately and respond with appropriate urgency and technique selection) A critical component involves understanding the danger levels of different ashi garami positions - from relatively safe positions like standard ashi garami where escape time exists, to immediately dangerous positions like inside sankaku or fully developed saddle where finishing can occur within seconds. This knowledge dictates urgency of defensive response and appropriate escape protocols for each position type.
Hip Alignment Mechanics (Deny optimal finishing angles through superior positional understanding) The core defensive principle centers on maintaining proper hip alignment relative to the opponent’s hips and body position. When hips remain square or facing toward the opponent, finishing mechanics for heel hooks and ankle locks become extremely difficult regardless of other control factors. The system provides specific drills and positional awareness to maintain this alignment even under pressure.
Systematic Clearing Sequences (Provide reliable escape pathways that work against skilled leg lock specialists) Rather than explosive scrambling, the framework teaches specific clearing sequences for each major leg entanglement position. These sequences involve methodical removal of opponent’s hooks, recovery of inside position, and re-establishment of safe distance or position. Each sequence has clear checkpoints and contingency options based on opponent’s defensive reactions.
Counter-Attack Integration (Turn defensive situations into offensive opportunities and discourage aggressive leg attacks) Advanced practitioners learn to transition defensive sequences into offensive leg entanglement opportunities. The system teaches how to use opponent’s commitment to leg attacks as opportunity to enter their legs, transition to back attacks, or establish dominant passing positions. This transforms defense from purely reactive to strategically advantageous.

Expert Insights
- John Danaher: The Lachlan Giles defensive framework represents one of the most scientifically rigorous approaches to leg lock defense that has emerged in modern jiu-jitsu. What makes this system particularly effective is its emphasis on hierarchical understanding - recognizing that not all leg entanglements carry equal danger, and that defensive responses must be calibrated to the actual threat level rather than responding with maximum urgency to every leg touch. The system correctly identifies that the majority of successful leg lock defenses occur at the prevention stage, before full positional control is established. The mechanical principle of hip alignment as the primary defensive consideration is absolutely sound - when you maintain proper hip positioning relative to your opponent, finishing mechanics for heel hooks become geometrically impossible regardless of grip strength or flexibility. This represents a shift from attribute-based defense to position-based defense, which is the hallmark of high-level jiu-jitsu. The systematic clearing sequences provide what all defensive systems require: reliable pathways that work through technical precision rather than hope or athleticism.
- Gordon Ryan: Lachlan’s defensive system is competition-proven at the highest levels, which is the only metric that really matters when evaluating any jiu-jitsu framework. Having competed against him multiple times, I can confirm that his defense makes leg attacks extremely difficult to finish even when you achieve positional dominance. The key insight from a competitor’s perspective is that his system doesn’t just prevent submissions - it actively discourages opponents from attempting leg attacks because the success rate drops so dramatically against trained defenders. This creates a psychological advantage where opponents second-guess their leg lock entries, knowing they’re likely to end up in neutral or worse positions. The counter-attack integration is particularly dangerous because it turns what should be an offensive advantage for the attacker into a defensive liability. When I face opponents trained in this system, I have to be much more selective about when and how I enter leg entanglements, which limits one of my primary offensive weapons. The competition application of this framework has fundamentally changed how elite no-gi matches play out.
- Eddie Bravo: What I respect about Lachlan’s approach is that it doesn’t avoid the leg lock game - it engages with it intelligently and turns defense into offense. That’s the 10th Planet philosophy applied to leg locks: don’t run from the game, master it from both sides. The position hierarchy concept is crucial because too many people treat all leg entanglements the same, either panicking immediately or being too casual. Understanding that you can work methodically from standard ashi but need to move urgently from inside sankaku is the difference between tapping and escaping. The system also acknowledges that flexibility and body type matter - there are multiple pathways provided rather than one-size-fits-all solutions. I’ve incorporated many of these defensive concepts into 10th Planet training because our lockdown and rubber guard systems can expose legs during transitions, so we need solid defensive foundations. The counter-entanglement aspect is pure jiu-jitsu chess - using opponent’s aggression against them. When defense becomes offense, that’s when you’re truly mastering the position rather than just surviving it.
