The Alexander Technique Manual by Richard Brennan (Waterstones, £17.99) explains coherently how the Alexander Technique evolved and the ways in which it can help to release muscular tension within the body. Demonstrations photographs are particularly good and compliment the text. This technique has aroused great interest among Dressage riders, since bodily tension or stiffness in the rider is immediately reflected in the horses way of working. If you suffer from back pain or muscular tension of any sort, the Alexander Technique is worth a try and this is the book to introduce you to it.
