I don't know much about the Pose Method but in my approach you are using propulsion to go forward. This is how our structure is designed to move, propulsion from the ball of the foot through the front of your body as if you are being pulled, not pushing from behind with your heels.
Learned rotation among other useful stuff, thanks!
What western medicine does not do is address how to access the brain to re-train a child how to move again so that the problems that occur later in life are avoided. Braces, surgery and stretching muscles do not address the 'pattern' that the brain has established in movement. A structural movement specialist does addresses the pattern causing the movement limitations and guides the child to re-learn movement. Search movement therapy of more information.
Glad it helped - there is another weight video on youtube and on my website so check it out too!
