Book to practice weight training with body weight at home, using conventional equipment (chairs, tables, stools, drawbar). This book specifies the strength exercises with the number of series and repetitions to have a consistent weight training program for the entire body. We must put the "110 years" for a fiscal year to a range of motion exercises then the total is incremented quickly through this. For example, there are several pull amplitude variation so that's at least 3 exos to ^^ meters. It should also relativize the "no material" because it needs a pull-up bar etc ... but it's still no sports machine ... An active community can be reached on the web via facebook, forums or the author's blog. Unfortunately, the comments are not very objective because the majority of comments going against the direction of the method are removed (I have paid the price and I was treated fly because I said Emmanuel Akermann had made a equivalent book). For fans, it is the ultimate method and there's nothing else. I suggest you remain objective and not to be locked in this exclusive lafay-circle. The author believe that he invented a method unusual, but in fact he just formalized what many had in their youth, doing push-ups pumps etc ... Instead of using programs with dumbbells here, use your body weight, nothing more ... The muscles will not get out of work, I assure you ... But this book is a very good book, I do not put 5 stars because of the catchy title of the book that we must take the 3rd degrees and all tappage fact that the author on the web that I was very disappointed. .. (I allow myself to judge what the author on her blog because his blog is quoted in the book)
