Learning to do ride the posting trot correctly is a difficult and important step.  In the beginning it can be tough to understand what the horse is doing and how the rider is supposed to move to stay in rhythm with the horse. This video clip is short and sweet.  It uses “slow motion” to give clear examples of the concepts and movements.  These slow images are helpful  because once you know what you are looking for, it is much easier to do in real time.
