Today’s grappling class revolved around a sequence of leg locks. There were four of them: the calf strangle, the heel cup, the knee bar and the knee chalk. The calf strangle is when you trap your partner’s leg and then use your radial tuberosity (that bump at the end of your radius bone) and dig it into the belly of your partner’s calf muscle. The heel cup is similar – in that you need to trap a leg – but instead of attacking the calf, you hook your partner’s heel with your (once again) radial tuberosity and twist the heel until they tap.
It’s the next two submissions that give me trouble, which is why I wanted to work on them – the knee bar and the knee chalk. A knee bar is similar to an arm bar, in that you’re working against a hinge joint and different in that you’re going against a leg instead of an arm. The knee chalk (or any chalking submission for that matter) is when you shove an object (in this case, your shin) in the back of the knee pit and then close the joint by moving the heel towards the hip. Press far enough and the knee joint will be pulled apart.
The neat part about going over a sequence like this is to see if anyone can actually use any of the submission during the free grappling time. They did. Practice works.
