As someone who has also lost over 100 pounds, I was happy to read a book written by another "big loser." The author lost 120 pounds by using kettlebells and the book is about that. The type is big and there isn't a ton of new information in the book, but she talks a little about her history and how she lost the weight. There is a section on instructions for kettlebells and workouts you can do on your own, complete with photos. There's a chapter on food and recipes, as well.
I've done kettlebell workouts before and enjoyed them and I think the book is beneficial to newbies.
However, there were things that annoyed me about this book. First, the book is written as if she's an expert, except that the "facts" she presents do not have annotations citing where she got her facts. I wanted to see where she came up with the "Fact" that women should eat only 1200 calories a day. (I've seen a nutritionist and was told 1200 is too low for most people, especially for active people.)
Second, she was very anti-gym. She belittles gyms, people that workout in gyms, she claims that cardio is worthless, that lifting weights creates "bulky" and awkward looking muscles on women and then says she can do kettlebell workouts 3 times a week for 20-30 minutes and be good. Well, good for her. *I* actually had great success losing weight in a gym and I see no problems with any of it. I swim, bike, run because I LIKE it. I lift weights because I like it. Who cares if it's not the most efficient way to exercise? If someone enjoys doing an activity, I say go for it. Physical activity of any kind of crucial for healthy living.
Lastly, the book felt gimmicky. She used a lot of buzz words like "Rapid Weight Loss" etc etc and that turned me off. It took almost 2 years of hard work and dedication for me to lose 110 pounds and it's a major turn off to see books/magazines that say "LOSE 50 pounds in 1 month!" etc.
