Best fitness trackers in 2021: Top activity bands from Fitbit, Garmin and more


The best fitness trackers are good tools for getting more active, getting more sleep and getting more insight on your overall health. They can help you track your progress and offer guidance on how hard you should be pushing yourself, too.

As exercise-oriented wearables, fitness trackers can measure your heart rate, read your blood oxygen levels, accompany you swimming and tell you if you’re well-rested. When you’re not working out, some can be used to pay for groceries, play music, answer texts and much more.
