Christoph Hess works on stretching with an upper level horse and applying that essential balance to flying changes, canter pirouettes, and the half steps.
We join this pair mid-warmup. (The rider they are speaking of is Eventing legend Bruce Davidson.) They work canter trot canter transitions on a long rein without using the reins. Interestingly they work some flying changes on a very long rein without helping him allowing him to jump through the change.
