As I am sure you are aware it is a tohei method, as a ki aikido man yourself you probably know more about it than I do. Wouldn't know what the concencus is, that it just my limited understanding of it. We don't actually practice it very often, pretty rudimentary stuff though.
If you have different or another explanation feel free to elaborate.
Just curious Keith as I have seen discussions on this kind of thing before and seen people going into discussions on muscles and contractions etc.
When it comes to such things I personally can do unbendable arm or let's say the tests of being unable to be lifted up with two people trying one on each wrist by various methods rather than just one. So I'm just interested that's all.
Anyway good on you for posting your view, like you I look foreward to reading more perspectives.
