10th Planet Jiu-jitsu is a living system of jiu-jitsu developed by Eddie Bravo that continues to evolve as new methods are introduced and old techniques continue to be refined. The result is a body of moves that have been proven to work on the mats, in the streets, and even in the Octagon. 10th Planet is a no-gi only system that utilizes clinches to hold opponents close while moving into various submissions. There are four core elements to the 10th Planet system: The Lockdown (a variation of half-guard), The Truck (an alternate form of back control), Rubber Guard, and Leg Locks.
