Toy Ma Gahng/Jom Sau (Retreating Stance Pivot/Low Sweep/High Chop Block)
In an action that covers the entire Centreline but does not change the line created by the previous motion, slide the right foot backward, passing through the gap under the Dummy Leg to a point not past the Original Centreline and pivot both feet to the right.
This footwork brings the stance to a right Inside Facing Choh Ma position. During the sliding step, begin the Gahng/Jom Sau motion by snapping the right wrist inward and circling the arm into a low outward/forward Sweep Block as the left arm circles up to Jom position. Both motions simultaneously make contact with the Dummy in time with the pivot.
At the completion of the motion, the right arm should be angled so that the tucked thumb points towards your Centreline and the left hand cuts into the Centreline itself. The power of both arms, although apparently sweeping sideward to the right, is focused directly towards the Dummy's Motherline.
Power starts from the heart and shoots straight to the core of the Dummy.
