Re: Video definitions, "Aiki" and other terms.
Thanks for the videos, now we are starting something.
In the first video, if that is what you mean by staying 90 degrees in that situation, I stand corrected. You can receive some force in this manner. When you asked the first time, I thought you meant a full force push (as I showed in my second video). To a degree, everyone can resist some force this way, but the amount is minor.
This brings me to my next point about what you call "Aiki" (if these are examples of what you call "Aiki"). There is a major limit to what it can do with it. Even if this limit seems better then normal, it is still very limited. For example, with my push (second video) I can do that with a normal person, I've even done it with two people pushing as hard as they can, but there is a limit. For example if a Bull were trying to push me like that, he would just run me over, his structure is stronger then mine.
However looking at "Aiki" the way I do has no limit. You can use what I call "Aiki" on a bull easily, in fact people do it in Spain all the time.
My point here is, how much force must one be able to receive to be considered to have good "Aiki"? What is the point of being able to receive all this force? Isn't lifting weights something that could compare to this, in terms of force taking ability? Besides being an interesting novelty with some application, what good is this kind of practice, why develop a whole martial art system around it?
