i believed the IS folks would challenge those statements, in that, they can divert forces downward and/or in any direction they want. of course, those IS buggers would also said they can do other stuffs which seemed to defy logic too. in one of the post, mike sigman has a picture of a guy standing on one leg and another dude pushing. the picture has various color lines and so on (i think he liked to play with crayons
). there is a video of Ark where he stood in parallel stand and doing pushing with other folks.
some of our assumptions might not be as valid as we might led to believe.
Really? So if he stands in front of me, feet apart (shoulder width) and I push him backwards he can withstand that force without stepping backwards, without losing posture? Seriously? SHOW ME!
When they 'lean in' they can counter the force; oppose it. You would feel 'resistance' build up. When they deflect, they lose posture, do not control distance any longer.
If all that works so well why does every single martial art place one foot in front of the other (boxing, kendo, fencing, karate, kyodo, kungfu, wrestling, mu tai, bagua). The only one I can think of that does not do so is sumo, at least when they start. But even then look carefully what happens on contact (bodies turned, arms put rotating force in opponent)
No sir, nice try, but no cookie. Perhaps I am just ignorant stubborn, whatever.
Mind you, the exercises are valuable and have their merit, but no more than striking a boken a hundred times.
