My method, is movement, I can use my legs, or back to generate power, but it all comes from adapting to whats in front of me, my response is governed by my linking my breath and movement, in response to my opponents tension, I do not rely on elements of my body to create power, but can use them as you do, it could be discribed as the grey man theory, I hide my skill, until needed, and respond accordingly, movement is my power, my opponents movement,and tension, in stance, or movement in intension, is my guide, never stop moving, never stop breathing, never stop watching, never stop feeling, never stop learning, that is my method.
