So much of what happens in an aikido technique is about hips.
When we discuss how uke`s balance gets broken, it is often in the context that we connect uke to our hips, our center of power, and from there our motion takes uke`s balance naturally.
Low hips = low center of gravity
A vital part of how smaller people use these techniques very successfully against larger people. The fact is, the breaking of uke`s balance is even more dramatic the lower shite`s hip line is in comparison. Of course, shite cannot allow any lean forward or loss of kamae. Rather, proper use of the knees allows us to make that center of gravity lower. It is especially evident in how powerful the kneeling techniques are against standing opponents.
The more we train, the more I am aware that body momentum (from moving) is less the focal point that the hip line and center of gravity. Now I believe that the objective is to use the arms/hands to connect uke to our hipline, and mobility to direct that hip line low to the point that most quickly and efficiently breaks uke`s balance.
Back to the lab as soon as I can to test this one out.
