Pacewalking P

Even bodybuilders have caught on to the benefits of walking; they call it ""power walking.'' Here, Jonas (Triathloning for Ordinary Mortals, etc.), professor of preventive medicine at the State University of New York at Stony Brook, and Radetsky (coauthor of Peak Condition) systematize their own adaptation of that aerobic-fitness method, elevating walking to ``the Foundation Aerobic SporT: F.A.S.T.'' With attention to the elderly, injured and pregnant, the innovative pair pinpoint daily and weekly training programs, work-out techniques, equipment, recent nutritional advances and insights on the health-exercise link. For those active in other sports, there is guidance on preparation with the variant ``PaceTraining.'' Emphasized here is the enjoyment of aerobic walking for exercise and health, and an appendix lists walking clubs and organizations nationwide for those ``PaceWalkers'' who seek the company of others.
