What a great surprise. Here is an inexpensive manual with clear definitions, excellent photographs and diagrams as well as sections on what not to do, what can go wrong and how to fix it. The exercises build from basic to more advanced. I found her half-halt method to be simple and subtle but worked to stabilize even my NASCAR-minded mare. She suggests multiple methods to determine the correct timing to apply the aides. This book was recommended by a friend and I believe it is the most user-friendly, helpful book in my library. I'll pass the recommendation along to you wholeheartedly.
