Like every piece from the equipment 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 also have to suit your lifestyle and when and how you like to train. Have you just bought a Peloton or can you only take a lunchtime walk? The studies are mixed on their benefits, but there’s never been a better time to find a powerful and sophisticated tool to help you optimize your workouts or just get started a few more steps each day.
Update March 2021: We’ve removed old picks and added new trackers, like Amazon’s Halo.
