Here's a typical classic anticipation and overshoot. Moving away from the start pose and then going past the end pose - then settling into the final pose gives the action more space. More space for the same amount of frames = a stronger accent. If the animator had just inbetweened the start and stop pose, the action would have had no impact. It'd be mushy.
