At 93, LaLanne—the man credited with starting America's "fitness craze" in the 1930s—exercises two hours a day, seven days a week. "I hate it, but I like the results," he says. "Exercise is king, nutrition is queen. Together you have a kingdom." Based in California, LaLanne continues to give lectures and conduct fitness seminars, traveling with his wife of 54 years, Elaine, with whom he has three children.
