Lately it seems like wrist locks are becoming a more popular trend in Jiu-Jitsu competitions. I have also taken a liking to them. Why not?! They can end a match quickly and are often overlooked by most grapplers. I find myself looking for them more often these days while training at my own gym. I stumbled on this particularly nice wrist lock set up as shown by Gracie Barra elite competitor Otavio Sousa. The set up is based on having your opponents back and is a response to them defending in a particular way. Check it out and as always, go slow on them with your training partners!
