Early in the 1990s, I flew alone in a dandelion-yellow, single-engine, 180-horsepower Piper Cherokee from Westchester County Airport in New York westward to the Rocky Mountains, landing and refuelling a good many times in middle-sized cities and towns along the way.

For years, I always thought it was hilarious that I was this fitness guru, because fitness was just a tool I utilized to help people improve their confidence. For me, it's never been about fitness. It's always been about helping to empower people.
