When I accepted Fitbit’s two-week Step It Up! Challenge, my hope was that we would tap into America’s competitive spirit and get everyone to walk more. The challenge was designed so that folks could team up and invite others to step it up, too. While some participants seemed to really enjoy competing and comparing their step count with mine, the real goal wasn’t about who walks more or less. It was about establishing a habit that would set us on a path to a stronger, healthier nation.
