Practicing bodybuilding for many years I decided to learn more about kettlebells. So I purchased this book in French very well designed. The pictures are very well done and the author is really passionate subject, in collaboration with Jerome Banner that we recognize its qualities as an international fighter, with or without a smile, whatever. The movements are very well cut and the end of the book we look forward to procure these dumbbells to experience the bénéfices.Ne not consider the first to comment on this book, the author probably did not have the possession. Best Regards
