Arnold Schwarzenegger hasn't competed as a bodybuilder since he won the Mr. Olympia title in 1980, but he remains the sport's No. 1 icon. He hosts an annual bodybuilding contest in Columbus, Ohio, and allows a column to be ghost-written under his name in a muscle magazine. Today's bodybuilders may have bigger muscles than Arnold ever did, but everyone inside and outside the iron game gives him credit for exponentially broadening the popularity of physique training.

With this updated Encyclopedia (it was originally published in 1985), Schwarzenegger wraps his huge arms around the entire sport. He hits the history of bodybuilding, the champions (he's quite generous in his praise of predecessors, contemporaries, and successors alike), the training systems. Some of the information is more bodybuilding lore than science; for example, exercises are said to "expand the rib cage" or develop the "inner" or "outer" chest, all physiological impossibilities. But they're still good exercises, and the book includes every movement imaginable for every muscle group.

If you love the sport of bodybuilding, you'll want this book in your library, if for no other reason than to feast your eyes on the hundreds of photos of the best physiques in the history of the sport. And, in a pinch, the 800-page encyclopedia can fill in nicely for a missing dumbbell. --Lou Schuler
