Looking at the development of equestrian art over longer periods of time, you will detect pendulum-like swings of opinions in many areas. There are fashion trends that are taken to a certain extreme. Then, opinions change, and the pendulum swings in the opposite direction until it reaches the other extreme. Although these developments are often based on correct observations in some areas, extremes are usually counter productive and often damage the horse’s soundness and overall health. It is always dangerous when an observation of one training aspect is made the only criterion for evaluating training progress and then taken to an extreme, following the motto: more is better.
One example of such extremes are two diametrically opposed opinions on riding long and low. On one end of the spectrum are those riders for whom stretching forward-downward is the highest goal of dressage training and the solution to all problems. Many of them believe that you are not allowed to do anything else in the training of your horse until the horse is able to stretch forward-downward. On the opposite end of the spectrum are those who categorically reject any and all forward-downward stretching because they believe that it puts the horse onto the forehand and ruins the horse’s legs.
