Re: A simple mechanical model of body use.
i was going to go through various posts and answer individually, but i am lazy (my philosophy is if you can sit down, then don't stand up. if you can lay down, then don't sit) so i'll post my comments here.
simple mechanic such as lifting something isn't simple in IP/IS point of view. From IP/IS point view, we have a number of requirements that we follow
1. one moves, all move
2. dealing with force in one direction, one must also deal with forces apply in all directions: front, back, left, right, up and down, at all time.
3. 1 & 2 don't mean you sacrifice mobility
4. heart leads mind. mind leads chi/ki. chi/ki leads motions.
5. breath power is a must, not a nice to have. and i don't mean sucking winds to live or onion breath.
Those are some of the foundational things that govern IP/IS process.
