I'm reading an interesting book about fitness called Which Comes First, Cardio or Weights?: Fitness Myths, Training Truths, and Other Surprising Discoveries from the Science of Exercise by Alex Hutchinson. The book offers short chapters of information about common health and exercise questions, such as "How long does it take to get in shape?', "Is the elliptical machine just as good as running?", and "How should I warm up before I exercise?". Journal articles and interviews are referenced, but I really like that it's easy to understand, tells you if there is no definitive answer or if there are several possibilites, and you can skip around easily, reading what you're most interested in. While there are plenty of good tips, I don't expect to be coming anywhere close to running the New York Marathon in 2:23:15 (top women's time). I just want to walk a mile easily in less than 15 minutes.
Hutchinson also writes a fitness blog called Sweat Science if you'd like to read more.
