Apart from a couple of good points (especially the section on forces) I hated this book! It lacks details and it's of little use when it comes to recreating the techniques described. The author is very opinionated against classic mountaineering techniques but doesn't offer a sensible alternative for the inexperienced climber; the approach to mountaineering offered in this book appears a good alternative for the experienced classic climber who wants to try something different. Being a climber with intermediate experience I feel the classic method makes more sense from a learning and practical point of view, plus it offers a more systematic approach to techniques and safety. However I agree with the author when he says not to take everything from the classic method as universal truth, instead use your head (this is why I liked the section on forces).
The sections on nutrition, training and psychology are a joke! Just superficial notions taken from more specialised sources! Get a good book on sport nutrition and motivation instead.
