How to step in Sanchin Kata

In the video we look at two stages of the Sanchin step method.
Some people have asked about the back foot angle (which we address below), however that aside the video specifically addresses the difficult problem of how to keep the abdomen engaged during the step.
Regarding the back foot angle; straight or turned in: Ultimately Sanchin is about symmetry which then instructs one in important concepts that are concretely relevant to discovering and encouraging efficient movement. I’ve found a couple things about keeping the back foot straight (in the beginning anyway); it tends to draw attention to the back leg over the front leg in order to preserve hip alignment, it scuttles alignment of foot/shin/knee/femur when attempting to bring equal focus to front and back leg, it encourages narrowing of lumbar region rather than the desired widening. Furthermore, when one utilizes Sanchin dachi in a free stance the straight back foot disengages the back hip weakening the ability to drive forward.
