I liked this book, with a few reservations. The photos were exceptional, very clear and detailed. The explanations were lovely, and I had no quarrel with the exercises for the most part. I'm not a big believer in isolating eensy muscles like hip ab/adductors, but I know lots of people prefer to work one muscle at a time. The routines struck me as not particularly challenging, and certainly nothing that would encourage a lot of growth (to the credit of the authors, they did explain how to modify said routines). My biggest complaint about the book is that the female models had no visible muscle development at all. Maybe a little ab striation. And in the pictures, the women are shown using 2 or 5 pound weights. I disapprove. Most emphatically. ( )
