Arm-twisting is when you push someone until they agree to do something they do not really want to do. The picture is of twisting a person's arm until it hurts; in real talk it is usually pressure, not a fight — a boss who will not stop asking, a friend who keeps calling in a favour, a politician who is leaned on to vote a certain way.
