Re: Elbow Power
Elbow power? I think it's just basic physics.
If in katatedori or any wrist grabs like morotedori, the wrist is your axis and the forearm the lever. Wrist grabs will be considered a class 1 type lever if you want to displace uke with minimal power and maximum carrying effect. It just so happens that the optimal lever fulcrum is from the elbow to the wrist. Nothing mystical about it. And as Endo sensei said, do not try to move what cannot be moved.
