How To Improve Your Sleep Game (& 7 Other Must-Know Fitbit Tips)

Have you ever spent all day walking around the city only to finally glance at your Fitbit and see that you've logged a mere 1,250 steps? Or maybe you check your heart rate after a hard run and discover that you've apparently transformed into a pulseless zombie.

Like other trackers (especially those that measure heart rate), Fitbits can prove finicky at times. Where and how you're wearing your tracker, the type of movement you're doing, and even your body's physiology can have an impact on whether or not you get correct data. Think about what happens when you take a rowing class or are doing dance cardio: Little changes in wrist movements can cause your band to loosen and affect its reading.

And since Fitbit regularly updates its app and hardware, there could be something useful and new you don't even know about — such as its new "sleep goals" feature, which just launched today.

There are easy ways to ensure greater accuracy and make sure you're getting the most out of your Fitbit, especially when it comes to taking advantage of the band's sleep benefits. After all, you didn't drop $130 on your Alta just because it looks pretty.
