Yoga has become enormously popular in recent years, with stars such as Madonna demonstrating the dramatic benefits in terms of well-being and physical looks. It has cast off its draughty church hall image to become instead a stylish, lifestyle activity. Kisen is the star name in yoga teaching - his client list includes everyone from Jerry Hall to Geri Halliwell, whose whole body shape he so dramatically transformed. Yoga Pure and Simple is his first book, and sets out his immensely effective programme, combining various schools of yoga to provide the most steamlined way of learning and practising. The book is superbly designed and photographed, providing a clear practical guide to all the sequences as well as inspiration that is guaranteed to get even the most reluctant practitioner completely hooked.
