Eventually this synchronicity becomes unconscious.
We could all mimic each movement in isolation and generate a small force but the fluid connection of these forces from the ground up to the fingers is far superior and requires practice. Eventually this synchronicity becomes unconscious. Practice substitutes for thought and the muscles themselves recognize the appropriate timing for coordination. A practitioner can then consciously focus on observing his adversary and seek the appropriate time to trigger the build-up of unconscious momentum. Only practice and constraint nurture such unconscious coordination so that the mind can maintain focus on unpredictable surroundings and preserve the ability to act.
