Back to horizontal circling. Let’s add one more layer to this training.
Our leading hand is like Batman and our rear hand is like Robin. One leads, one follows and assists.
Your leading hand is like the front gate. Your rear hand is like a secondary gate. A discussion of doors and gates can be found on page 122 of The Ip Man Questions (2nd Ed).
Your rear hand adheres and listens to the movement of your training partner’s elbow. It actively moves about probing even as it is listening. Placed correctly it is an ally. At the wrong position it can be a liability so study this well.
