Is this not how one begins to operate when using a slightly refined seated kokyu ho dosa? You know the 'technique' osensei said to end every class with.
Of course! Scapula stabilization is a necessary part of kokyu dosa - but it isn't sufficient. Kokyu dosa, for me, doesn't begin or end with scapula movement; the scapulas do whatever they are gonna do as a result of what i'm currently working on, which is bowing/rippling my lower spine.
Scapula stabilization like this is also a training cue weightlifters use when doing stuff like the bench press ("squeeze your shoulder blades and drive them into the bench!"). And here, its necessary to lift safely and with maximum efficiency, but not sufficient to get that weight up there. And bench pressing is nothing like kokyu dosa.
