Query: This is the worst book on the subject of periodization!

I thought this book was terribly awful. Its more of a briefreview of periodization, not a book on the theory, and training. Itsalmost like a cheap, and sloppy version of cliff notes on Dr.Bompa's Serious Strength Training. I would not recommend Periodization Breakthrough to anyone. If you want the complete theory, and training methodology of Periodization for bodybuilding/strength training purposes, I very highly recommend Dr. Bompa's Serious Strength Training. It is I beleive the best written book on the topic!
