how do you position TO the inside after an incoming attack without moving your lower body?

Hi ED

And how would I get inside ED?
Your second question
or are the applications you practice assuming you are already inside?

My answer
They can be practiced stand alone yes.

Hi Ed again
The anwer to your question.Im going to be as cryptic as you normaly are.
so as I see it the kata Naifanchi,translated from okinawan
to "stepping with stealth"?
which is used as a "tanren"
kata on the birth place of karate.
To answer your question while still nodding my head and totaly agreeing with medulant in that some of you guys dont read what he writes.
Does the Naihanchi kata being practiced in the place where karate came from just use the horse stance?
http://en.wikipedia.org/wiki/Motobu_ChokiThis gentle man used Naihanchi.In fact the way he uses it exactly how I would expect it to be used from a "Fighter".
I have some where on my computer an old black and white film/vidio of him drilling it with another famouse karate ka.
They dont just use horse stance either.
So Im going to be cryptic here, just like you are in your own thought provoking way, and say to you seek out the old black and white film of him drilling the kata.Or look at the kata being used in the place karate came from. There in lies your answer.Then in one of your classes work out how to use the technique to get inside an attack
Practice the techniques as a stand alone method
Then have someone as i did throw full contact techniques at you and make the thing use able.
Then use what you have in full contact sparring.(but pull on some techniques after all ukes are of little use injured.
After all isnt that kata was for? Usable techniques?
No good to me if they have no use.Then it becomes a dance.
I dont mind your attempts at sounding harsh Ed, My training partners can be harsher.

How was your mawashi class?
