Written for riders who wish to extend their horses' athletic lives and make them better, happier performers, this guide defines the practice of collection and explains how to train horses in it. Collection, or self-carriage, involves a horse carrying more weight on its hind legs than its front legs, allowing it to move more easily and perform more beautifully--but it can be difficult to achieve. Exercises for varying skill levels, riding styles, and horses help riders learn what qualifies as collection and how to attain it. Tips on how to avoid the most common bad habits and mistakes are also included in this manual that is beneficial to riders and horses everywhere.
