Very interesting book that will suit everyone. Unfortunately there is a big downside: this book has already been published with another title and another presentation. As there is no possibility of flipping before you order it, it would have avoided to see the scam only to receipt of the shipment. Yes, it is indeed a form of scam perpetrated by the publisher, Amazon has nothing to do because it leaves the possibility for the publisher to let us consult the book before ordering. Too bad this editor proceeds in this manner because books (in general) of Delavier are very rich both in terms of exercises (there are for all levels) and in terms of advice and descriptions of targeted muscle groups. Both stars are less for the publisher only, not the author. Kudos to Amazon for the efficiency of its services for both the control (quick dispatch) as the most desired return merchandise.
