Why your fitness band might be lying to you

[MUSIC] If you're using a fitness band and it hasn't been calibrated, you're doing it all wrong. I have some bad news for you. Whatever mileage you track today will [MUSIC] But you might have worked more or less than what [SOUND] your fitness tracker is actually showing you. That's because, by default, trackers calculate the distance by multiplying your walking steps, and walking stride length. And stride length is set by using your height and gender. So if your tracker gets your stride length wrong, then your distance is wrong, too. The good news is that if all you care about is how much you're walking relative to yesterday or tomorrow, then your tracker isn't really letting you down. But if you're like me and you want your fitness data to be exact, then you'll have to calibrate your device. The way you do this depends on what tracker you're using, but here's how to do it for Fitbit. Head over to a place where you know the exact distance, like a track. Now, walk that distance and count your steps. Now you can figure out your stride length by dividing the total distance in feet by the number of steps you took. When you have that number, head to your FitBit dashboard and update your new Stride Length. If you have an Apple Watch, check out Dan [UNKNOWN] how-to on calibrating it. And now you're doing it right
