The standing arm drag is a simple illustration of the key principles behind the arm drag. With so much space present, you can clearly see how I move forward into Darryl, using my two-on-one grip to maneuver his arm a few inches to the side, just enough to clear the way. As soon as that space opens, I close it by stepping forward, locking my shoulder against Darryl’s. By filling the space I just opened, I block Darryl from regaining his posture. You will see this again and again in every application of the arm drag: moving the arm out of position and then locking it there so that Darryl cannot easily correct his mistake.
