No, then is when you intercept or destroy his set up. If someone swings his arm back in preparation to punch me, a simple and quick eye jab usually does the trick. Once he flinches from the surprise, then you blast. His arms go up as he goes back to protect his face, then you trap, get his arms out of the way and continue to blast. From here he will either end up on his back, in which you should turn and run. Or you can get close enough to employ headbutts, knees, elbows, or a grappling finishing move like a break or lock. If the person is considerably taller where you can't easily punch him in the face, get one of those ladders that have the wheels on it, then repeat procedure. It's great for balance!
