Query: Good for a beginner

There's not much to be learned here unless you've never stepped foot in a gym or are a relative beginner. Some of the exercises are shown improperly(e.g. the one-arm dumbell row shows the girl lifting her elbow above her torso at the contracted position - a great way to experience rotator cuff surgery and elbow tendinitis - not uppper back development).I would say that I learned something from this book, but the fact is I didn't.
