No, no, I meant no challenge at all. Bob can do whatever he wants, but since this board is read by people of all different levels of experience, I just didn't want his post to be out there without someone pointing out that most of the time, it's probably a bad idea to leave your hands at your sides. If you can do this regularly with impunity, it's probably time to seek out better sparring partners.
Aww! Guess there's no show here. Move along folks. Get back to your discussion of stances!
Just like everything else, the stance is a tool. If you don't do it long enough to get it, there's not much use for it for YOU!
Reminds me of a little story. Only peripherally related...I like to visit other instructors and sometimes they invite me to work out. I worked out in the very nice studio where first thing we do is go to a stance, of course. Immediately the instructor says, "Oh, I gave up on those traditional stances years ago." Oh, well. I took it as a compliment. Of course he felt he had to say something to let his students know he expects them to think my stances are wrong! I still enjoyed his class.
Don't you think it's little comments like this that make it difficult for martial artists to get along? Especially if the visitor takes it in the worst possible way. I have seen that happen.
Personally, I think my stances have been the key to my developing better rooting and balance, but that is because that is what I have done. I cannot know if higher stances would have given me the same knowledge because I have always done low stance arts.
