During class last month my instructor, Mark, said you should be attacking high and low. When your arms are bound up then you should be working with your legs to get sweeps, create space, or anything that will increase your position. Like wise if you legs aren’t being effective then work with your arms. I’ve taken this to heart and tried to remember to move my mental focus to the part of the battle where it can be most effective. In doing so I realized I didn’t know any leg attacks. This has led me find 5 leg locks that I think are a good starting point to build my arsenal. All of them come from Encyclopedia of Leg Locks (Encyclopedia of Brazilian Jiu-Jitsu) by Rigan Machado. Last night at class we went over some more purple belt test techniques. After class I got two of the more experienced guys to go over one particular leg lock with me so I could get a good feel for it. One disadvantage to my Submission Master Grappling Dummy is he feels no pain. I get good reps on him but I first have to make sure I’m doing the technique right. In keeping with my idea to give techniques more memorable names, I have dubbed this one "Cobra in the Grass". It is found on page 60 of Encyclopedia of Leg Locks. The below videos show the "snake" motion I use to get the first part of the leg lock.
These give you the idea of how to get the legs. After that you need to get your knee on the belly that is opposite the arm that is holding the legs. You do this by controlling the hip on the same side as the arm that has the legs. Once you have the knee in the belly you lay back and swing the opposite leg around the opponents hip. If they don’t straighten their leg you will get a calve cutter right off and if they do then you roll into the straight leg to get the leg lock. I know my description isn’t the best. I’ll try to get video of it next class.
