I bought 4 copies of this book, 3 paperbacks and one Kindle, you should too - "Weight Lifting Is a Waste of Time"

 I do my research by buying other people's books, which saves me some time, and I have to say this book changed not only my workout routine but also the way I look at my fitness. Some say that the guy is a genius, a mad genius. I don't know about that but I have to say that he convinced me. He seems to have done very good research and his conclusions seem to be right on the spot. 

The book is not that expensive and not that long. It's not boring either. I highly recommend it.
