I have had this book almost a week now and read it completely through before I opened the DVD. My first impression was that this looks exactly like a toning and shaping class I took in college some--well, let's just say it was a loooong time ago. I loved that class. It combined many of the same methods that Tracy uses in her class. The class that I took was half stretching and half dance. I have never had to much fun in my life while getting into shape. One note, the DVD is in black and white which is really nice for a change.I am starting out very slowly with the exercise since I do have a bad back. This book is not for everyone. You really do need to devote the time and energy. To be honest, it took me an hour and half to get through the first set of movements, but each day it does get easier and quicker. I have not followed the diet at all, but have lost two pounds and can already see a massive improvement in my arms and legs. Seriously, the bingo wings are fading!The recipes in the book look exceptionally well and it looks like I can get most of the ingredients at my local Trader Joe's. There are quite a few chicken dishes that I really want to try, especially the one with mango.
