Mark Fenton sure likes to get around. That's him in Supersize Me, handing actor/director Martin Spurlock a pedometer and talking about the state of the nation's ever-enlarging waistband. And on his PBS series, America's Walking, he's inspired millions to do something about it. You can count on seeing Fenton almost monthly on the pages of Health, where he's a contributing editor, in magazines from Parade to Prevention, from the LA Times to the New York Times, and in communities across the country launching walking programs and helping to build more walkable streets. No wonder the Washington Post calls Mark Fenton "America's reigning guru of walking."What compels him to do all of this? Fenton thinks it's high time for his fellow Americans to get around as much as he does. In Pedometer Walking, he teams up with top exercise researcher David R. Bassett Jr. to help readers get moving, and the good news is that with a pedometer you soon learn that every step counts. In case you haven't heard - or seen Oprah wearing one - this handy little device packs a mighty motivational punch by actually recording your steps for you. With the current recommendation of at least 10,000 steps a day for good health, fitness, and even weight loss, you'll find you can rack them up while grocery shopping, walking the dog, and even stepping out for lunch.With solid information about choosing and using a pedometer, insights into building a step-friendly lifestyle (and neighborhood), and a six-week program to get you started, Pedometer Walking may very well be one of the most important exercise tools in years.
