Real Grapplers, Real Results
“I’ve been training with Jack Brown for over four years. He completely changed how I think about Jiu Jitsu. Jack is a leg lock specialist, but he’s got a full game. One of the best black belts to come out of Scotland.”
- Chris 'The Problem' Duncan, UFC lightweight powerhouse
“Jack’s got a sharp eye for detail, breaks things down clearly, and actually knows how to coach — not just perform. My understanding of leg lock entries, control, and finishes has gone up massively since training with him.”
- Mark MacQueen. ADCC European Trials Winner. 2 x IBJJF European Champion.

Proven Under Pressure - Jack Brown's System
Competitor. Coach. Quiet technician with a brutal finish rate.
Jack Brown isn’t loud, but those who’ve rolled with him knos: he’s a problem. A black belt under the meticulous Marcos Nardini, Jack's known for his ruthless control, calm presence, and clinical finishing under pressure.
Jack honed his skills through relentless study and live-fire competition. He’s submitted some of the UK’s best under the bright lights of ADCC Scotland, Grapplefest and Evolution of Combat, and his system is built for pressure.
His methodical, ice-cold style has become a hallmark of his game—setting traps, locking control, and finishing with precision under pressure.
Jack has coached all through Europe and Asia and is one of Scramble BJJ's Elite sponsored athletes.
This is the first time Jack’s full and updated leg lock system has been made available outside the gym. Whether you’re coaching, competing, or just levelling up your no-gi game, this course delivers the tools, the timing, and the technique to dominate the lower body battle.
Train with intent. Attack with precision. Win with confidence.
