As fitness trackers like the Fitbit Air become better and better, they are now remarkably good at finding new things to measure.Open the companion app after a workout or a night’s sleep and you'll be greeted by a dizzying array of stats: steps, heart rate, HRV, sleep stages, VO2 max, calories burned, and many more besides.Some of that information is genuinely useful, but a lot of it is better treated as (interesting) background noise.The trick is knowing which numbers can tell you something meaningful about your activity or recovery — and, just as importantly, which ones you can actually do something with.For most of us, though, that leaves a much shorter list than the dashboard might suggest.
