Like every piece of gear you wear on your body day in and day out, fitness trackers are incredibly personal. Not only do they have to be comfortable and attractive, but they must also accommodate your lifestyle, as well as when and how you like to work out. Do you bike, row, or do strength training? Do you run on trails for hours at a time, or do you just want a reminder to get up every hour?
No matter what your needs, there's never been a better time to find a powerful, sophisticated tool that can help you optimize your workouts or jump-start your routine. We've tested dozens over the past four years to bring you these picks. While you're at it, don't forget to check out our guides to the best smartwatches and best running gear.
Updated December 2021: We updated our picks with this year's new releases and updated pricing and availability.
