“Malibu resident Don Wildman, possibly one of the fittest septuagenarians on the planet, has always had that galvanizing effect on people. Founder of the company that became Bally's Total Fitness, the giant health-club chain, Wildman not only made a career out of telling people to get fit, he fit the part himself, packing his life with daily workouts and an endless parade of grand physical challenges -- world-class sailing races against Ted Turner, 90 holes of golf in a day, nine Hawaii Ironman triathlons. The activities didn't retire when he did 15 years ago. He picked up big-wave surfing, helicopter snowboarding and stand-up paddle boarding, once paddling the length of the Hawaiian Islands. Every Monday, Wednesday and Friday, he leads "the Circuit," a grueling two-hour weight workout at his gargantuan home gym that has become legendary in Malibu. He rides seven days a week and paddles three. "I don't rest," he says.
