Really good book to trigger your imagination and allow you to be more creative in exercising your horse, great illustrations to emphasize points and help demonstrate certain exercises and locations. Somewhat irritating was the repetative safety precautions stated on virtually every page but i suppose it is a must and all relevent and necessary. It also assumes you are at a level of schooling where the rider knows pretty much what they are asking the horse to do and which aids to give.
I am very glad that I bought this book, when stuck for appropriate schooling space or in a 'boredom' rut this really is the inspiration you need and i've had a lot of fun trying the exercises with friends while riding out!
