In class our review of kamae from the ten ryaku no maki section of training begins with learning the posture- where the feet are positioned and where the hands are positioned.
Two very important points at keeping the back straight and getting as low as possible in the posture. Really flexing the hips and knees in a deep posture. Get low and work on getting lower- some junan taiso stretching to work on getting lower.
Ichimonji, hicho, doko, jumonji, etc.
We then add some movement.
Walking around moving and shifting from kamae to kamae- keeping the transition as flowing as possible, making sure not to expose any kyusho. Action point is this movement is to keep and maintain the same height.
Walking and moving to a *low* ichimonji, followed by keeping the same low profile to the next posture.
Continuing to move but now changing directions- shifting to the side or even behind.
Working with a training partner, if one was to perform a waza- any waza and film it, breaking down the movement frame by frame, one would see numerous kamae and how they interplay with each other.
