Dynamic stretching is a movement-based type of stretching. It uses the muscles themselves to bring about a stretch. It's different from traditional "static" stretching because the stretch position is not held.
An example of dynamic stretching would be lunges with a torso twist, hip circles, arm circles, arm swings, etc
