This book is full of ideas to keep schooling interesting. I often get stuck going round on the same circle trying to get it right, since having this book I have been working on an exercise each time I ride which pushes us to try harder things and as a result my horse is more engaged and his basic way of going has improved without me fiddling and faffing on a boring circle. It doesn't matter if the horse is doing it totally correctly, just doing the exercises builds strength and engagement. The exercises do the work for you. I also teach and this book is also great for lesson planning. Highly recommended book.
