What is Danaher Leg Lock System?
The Danaher Leg Lock System represents a paradigmatic shift in modern Brazilian Jiu-Jitsu, transforming leg attacks from opportunistic submissions into a comprehensive positional hierarchy. Developed by John Danaher and perfected by his students at the Renzo Gracie Academy, this system treats leg entanglements as positions rather than submissions, establishing control hierarchies, transition pathways, and finishing mechanics that mirror traditional upper body systems.
At its core, the system is built upon the ashi-garami family of positions—a spectrum of leg entanglements ranging from outside ashi-garami (least control) to inside sankaku (maximum control). Each position offers distinct control advantages, submission options, and transition pathways. The revolutionary aspect lies in treating these positions with the same systematic rigor as mount or back control, establishing clear objectives for control maintenance, position advancement, and systematic breaking before finishing.
The system’s effectiveness stems from its emphasis on mechanical hierarchy over opportunism. Rather than attempting submissions from weak positions, practitioners learn to recognize positional deficiencies, advance through the hierarchy systematically, and only commit to finishing attempts from positions of overwhelming control. This approach has proven devastatingly effective in competition, with Danaher’s students achieving unprecedented success through leg locks at the highest levels of no-gi grappling.
Core Principles
- Position Before Submission - Establish dominant leg entanglement before attempting finishes
- Control Hierarchy - Recognize and advance through ashi-garami positional spectrum
- Systematic Breaking - Use structured approach to compromise defensive structures
- Mechanical Advantage - Maximize leverage through proper body positioning and alignment
- Entry Systems - Establish leg entanglements through systematic guard passing and transitions
- Defensive Nullification - Remove opponent’s escape options through positional dominance
- Bite Point Optimization - Achieve ideal finishing position before applying force
Key Components
Ashi-Garami Positional Hierarchy (Establish clear positional objectives and advancement pathways in leg entanglements) The foundation of the system is the classification of leg entanglements into a spectrum from outside ashi-garami (50-50), through standard ashi-garami, to inside ashi-garami (4-11 position), saddle/honey hole position, and finally inside sankaku. Each position offers progressively greater control and finishing potential. Understanding this hierarchy allows practitioners to recognize when they have sufficient control to finish versus when they must advance position first.
Entry and Passing Integration (Create reliable pathways from common positions to leg entanglement control) Systematic entries to leg entanglements are established through guard passing sequences, X-guard transitions, and seated guard engagements. The system teaches specific pathways from common positions like single leg X-guard, de la riva guard, and headquarters position into various ashi-garami configurations. This integration ensures practitioners can reliably access leg entanglements rather than waiting for opportunistic moments.
Breaking Mechanics (Establish reliable methods for compromising defensive structures and achieving finishing positions) The systematic approach to compromising defensive leg positioning involves specific sequences for removing inside heel exposure defense, straightening the leg, clearing the knee line, and achieving the ideal bite point for submission. These mechanics apply across all heel hook, toe hold, and knee attack variations, providing a unified framework for finishing from any ashi-garami position. The breaking system emphasizes gradual, systematic pressure over explosive finishing attempts.
Transition Pathways (Enable dynamic position advancement and attack angle variation within leg entanglements) The system includes comprehensive transition sequences between different ashi-garami positions, allowing practitioners to advance the hierarchy when opponents defend or to switch attack angles when direct finishing is blocked. Key transitions include outside ashi to standard ashi, standard ashi to inside ashi, cross ashi entries, and the critical advancement to saddle position. Understanding these pathways prevents stagnation and enables systematic position improvement.
