I have become the type of person that used to mystify me. I ... am a fitness fanatic.
That was certainly not the case a year and a half ago. Back then, like a lot of Americans, I was mostly sedentary (unless you count walking to meetings). Which is ironic, because, as a senior editor for NPR's science, food and health team, it is literally my job to know better. But, with two small kids, a full-time job and recurring insomnia, I didn't have the time or energy to work out. And I'm not going tell you how much I used to weigh, but it wasn't healthy.
