LOCKDOWN HALF GUARD

The lockdown is the half-guard variant developed and popularized by Eddie Bravo in the early 2000s, in which the bottom player figure-fours their legs around one of the opponent's legs and extends the trapped leg downward to immobilize the hip. The position is the structural foundation of the 10th Planet half-guard system and produces a distinctive set of sweeps and back-takes that conventional half-guard does not access.

The mechanics begin from standard half guard with the bottom player having one of the opponent's legs trapped between their own legs. The bottom player then figure-fours the legs around the trapped leg — top leg over the opponent's calf, bottom foot hooking the top foot, and extends both legs together to stretch the opponent's trapped leg downward. The extension neutralizes the opponent's hip mobility on the trapped side and creates the structural opening that 10th Planet sweeps and back-takes exploit. The position is rare in pure gi competition (the lockdown's mechanics depend on a slightly looser fit that the gi's friction interferes with) but extremely common in no-gi competition.

Eddie Bravo developed the lockdown as part of the 10th Planet system in the early 2000s and demonstrated its competitive viability at ADCC 2003 with his celebrated submission of Royler Gracie. The system has since been refined by 10th Planet's many black belts (Geo Martinez, Richie Martinez, Tony Pacenski, James Puopolo) and integrated into broader no-gi pedagogy. Defensively the lockdown is countered by passing to the side opposite the trapped leg (where the lockdown structure cannot follow), by hand-fighting the figure-four before it consolidates, or by attacking the bottom player's exposed back during the figure-four setup window.
