Query: This book is so far from complete....

Don't buy this book if you are an intermediate to advanced fitness enthusiast. I just made the mistake. The first half of the book deals with wellness, like what you should eat, the importance of cardio. The second half shows a bunch of ab exercises but fails to tell you which is most effective. I was hoping to be told. "This particular situp is the best one for suchnsuch..."Instead they were all lumped together, none standing out above the rest. It was like the author had a competition to see how many different movements he could come up with. While I may not be elequent in writing this, since Im so steamed at wasting money on such a terrible book, believe me when I say this is a waste of money:) Instead I would recommend Arnold's Encyclopedia or I think there was also a good one by Joe Weider-both of which say...there are a lot of dumb situp movements that do nothing...but these will give you the best results....thats what I was looking for...
