I'd recommend this book for just about everybody who lifts weights. Beginners can greatly benefit from it to learn good form right off the bat. Experienced lifters might also want to check it out because, a) there's always more to learn, and b) your form might not be as good as you think it is.
So what's the book about anyway? Well, the Cliff Notes version is that its a book on how to lift weights PROPERLY using a barbell. A few details:
-the book spends a lot of time discussing the details of all the basic barbell exercises, such as the squat, the bench press, the deadlift, the press, and the power clean. As you might have guessed, the book devotes a whole chapter to each movement. For instance, the squat is discussed on pages 8-63, while the bench press is discussed on pages 66-102- I give you the page numbers to show you how in depth the book goes into each exercise
-you'll learn a lot of details that are often times neglected, such as grip, and the placement of other body parts that are indirectly used during an exercise. As an example, the book spends about 4 pages discussing foot placement during the bench press exercise.
-the book is filled with pictures and diagrams. In fact its hard to find a page that doesn't have one picture or diagram on it.
-the book does also cover "useful assistance exercies" as well, such as chin-ups, dips, rows, barbell curls, etc.
The book ends with a nice section that talks about a lot of "miscellaneous" things, things such as the order of doing exercises, warm-up sets, nutrition, soreness and injuries, etc. As you can see, this is a pretty detailed and comprehensive book, a book I think all weight lifters, beginners and experienced, will get a lot out of.
