Solid information about weightlifting. Establishes a theoretical foundation, then explains how to do a small set of very effective lifts in exhaustive detail. Tells you what to do, and why, in order to increase useful strength. Definitely the best strength-focused program I've ever used.

The area where this book is weak is "programming". It describes a basic program (schedule of which exercises to do how often), but doesn't detail when to start modifying it.
