Wonderful breakdown of the nebulous idea of "fitness" into measurable quantities: strength, endurance, mobility—and how best to develop them. Teaches you the basics of the science behind how exercise works and how spend your time most efficiently in the gym, with some quality myth-busting along the way. One of the best things I've read on programming: a great resource for learning how to build and tune a fitness regimen, rather than cargo-culting a program and hoping it works.

Badly needs a copy editor, however.
