Query: No Benefit for Intermediate/Advanced workout crowd.

The first two reviews mislead me into buying this book. I was under the impression that it would be a valuable resource to add to my workout library. Unfortunately, it did not provide any indepth information that I didn't alreay have from reading other fitness magazines. This book is only valuable if you're just starting out and need to understand how to work out from A to Z.
