Need Help to stop child from hitting me

My thoughts are that you stop allowing it. If a child that age raised a hand toward me, it would never make contact. I would grab the arm, spin the kid(don't twist his arm-that would hurt him)put him on the floor in front of me in a hold. I would look him very square in the eye and let him no that he was NEVER to hit mommy. He'd know clearly that mommy would keep him from hurting her, himself, or anyone else. He'd stay there until he calmed down and apologized. He would then owe mommy some age appropriate chore for hitting. If you are opposed to any kind of holding, child is removed to his room until calm. He then would need to tell me why he'd been in trouble, apologize, and do an age appropriate chore. The fists hurt a great deal more at 16. It needs to stop now.
