However, just the right amount of extension will creat the pin and allow you to maintain you structure. As far as kicking goes, try it. If you see a problem, try to fix it or simply acknowledge a potential danger.
I would have kicked but was told not to, I was just supposed to try to use my upper body and get my shoulders oof the floor. This is why I wondered what the pin was for. My legs and hips were quite free so I could have done a number of things. My partner was turned so that she could see my lower body so she could have blocked a kick but of course one of my arms would then have been free to hit her with.
I am not critsising by the way, I was just confused about the purpose of that pin.
I can see how it is a good exercise for learning to mainain balance and not extend oneself too much(which I did). As for the ki extension which some people mentioned, I don't really know what ki is so I doubt I was practising extending it. Thanks for all the explanations, it makes sense now.
