I've been lifting weights for a little over a year, so have already experienced many of the benefits Kathy mentions in her book. I've lost 40 pounds and about 18% body fat by following a good diet and weight training at progressively heavier weight and added sets. Even though I am not brand new to weight training, I still found the book helpful. There is an anatomy chart, and Kathy dispels many myths about weight lifting, in particular that women shouldn't lift heavy or that they will get big and bulky from lifting. Also, there were a couple of exercises that I was not doing, so I was able to modify my current program a bit.
I tried using a trainer, but frankly have been disappointed, so I am now learning all I can on my own. Lift Weights to Lose Weight will be a book that I use. I like it much better than the accompanying video tape, which I have used briefly; it is not a very comprehensive workout.
I recommend this book to beginners and intermediates, and anyone who wants to learn more about the basic principles of weight lifting.
