Query: Weight training guide is comprehensive and clear

I think Weight Training by Design is a very comprehensive, clear and logical training method. The BAM superset system will get you pumped. The workout is nice because it's both quick and effective. The book is much more specific than other weight training guides I've seen, and covers a variety of levels of difficulty and intensity. It works for me because I like to have a few routines I can do depending on my fitness level and what I'm trying to accomplish. The authors give very detailed information and recommendations about diet as well. Not just what to eat, but when. This would be a great book to have if you've just starting weight training, or if you're been training but really want to take it to the next level.
