Re: Kokyu development for Aiki in Aikido
Well, for myself, I have notes about doing some rather simple things sometime in the future after I have a little more time to feel more comfortable with the new feelings. One would be a very simple ikkyo from kosadori -- Some of those "reeling" exercises (I think they were called) remind me very much of really basic movements to doing ikkyo in that case. On the very advanced side one for one heck of a test one could extend that into futari ikkyo.
Other things include simple hijiotoshi type techniques. Rooting into the ground then dropping everything as one integral piece.
More tools in the toolbox...
But I always harp on our aikitaiso and test them rather extensively (to the dismay of some students). I've increased my testing a bit and added a few things lately due to experiences. New ways of explaining helping the students understand what's going on.
