What Is a Leg Lock?

Learn what a leg lock is in this Howcast video about lower body submission techniques for jiu jitsu, judo, sambo, and mma.


All right guys, I'm here to tell you I'm Brad Desir. I'm here to tell you what a leg lock is. A leg lock is a submission that obviously incorporates the legs, one or both legs, simultaneously or separately. A leg lock is a combination of either a hip lock, a knee bar attacking the knee joint, a knee crush, a calf crush, an ankle lock, any of those are what a leg lock is.

The purpose of a leg lock is to hyper-extend the knee at the joint or hyper-extend the ankle at the joint. So the way the leg bends the leg bends in towards us, we want to bend it the other way. We want to pass 90, try to bring our toes to our head, and that's how you effectively applicate a leg lock. Now when you guys are practicing leg locks, you have to be careful, especially when you're attacking the ligaments via heel hooks.

There's no pain in heel hooks until the ligaments have torn. Knee bars and ankle locks, they hurt and they're just as dangerous as arm bars and shoulder locks. So just be careful, be mindful, be courteous. If you catch a heel hook, do not crank it. Just let it go, and if you're also on the same side, if you're caught in a heel hook or you're caught in a toe hold, acknowledge it, tap and start over.
