step up the stairs.
I've had my Fitbit for a few years. I started with the original Ultra, then upgraded to the ONE about a year ago. There were a few new features, but an interesting addition was the ability for the Fitbit to now track changes in elevation.
It was about eight years ago that I changed from being an overweight, stationary couch potato, to an active and fit individual. I do find ... I take the stairs a LOT more often now.
