I appreciate your ongoing work to make people aware that stretching muscles does not warm them up and can have adverse effects when they are used. Please don't change what I wrote ("conventional muscles") to just "muscles". I asked you an honest question, which you have overlooked.
I was not trying to be evasive or snarky. I am simply not aware of any difference between "conventional' muscles and other muscle and I don't divide my body into "those muscles I need in order to sew with" with" versus "those muscles I need in order to do aikido." In order to pivot, extend arms, tenkan, drop center, open hips, walk, roll, fall, etc the entire body (minus whatever parts may be missing or lack sensory or motor connections due to illness or injury) needs to be engaged and available, whether we are relying on muscle A or muscle B to "do" a particular action, so it behooves us to have the body as warmed up and supple as possible.
