Well, actually the book is full of mistakes and orthograhe certain phrases must be checked because of a very personal syntax translator, it seems that this bestseller has not been reviewed before publishing ... Pictorial illustrations in the mood gloomy voluntarily from a prison or confinement (garage?) Are in my opinion not very necessary, OK, the writer is former inmate and one can get to understand her imprisonment but here that all the graphic rests above it's redundant ... But hey, let this being only the form, the content it is very interesting: by its simple and very effective approach: no need sophisticated or expensive equipment, patient (too often overlooked!), progression, regularity, willingness ... or how with some basic (but hefty!) were all on hand to build muscles, especially acquire functional strength and muscular work in chain ... It also suggests to focus on his own feelings / emotions ... which one is sometimes cut with ready made programs ready to be ingested without "re-centering" staff. In short, a must have for thinking differently.
