The 8 Best Waterproof Fitness Trackers to Buy in 2019

For a basic, waterproof fitness tracker at a reasonable price, you can’t go wrong with the Fitbit Flex 2. If you’re a serious swimmer or triathlete, you may want one with more functionality (keep reading for more on those), but for a simple way to track your fitness, this band is a great choice.

The battery lasts for up to five days, and it tracks your activity day and night, even when you sleep. Whether you're going for a run or swimming laps in a pool, it will track all of your movement. The Flex 2 also provides vibrating and lighted reminders when it’s time for you to move. An LED display helps you know when you reach goals you set, and it will alert you when you’re getting calls or texts if your phone is nearby.

While this one comes with a wristband, you can also remove the tracking device located inside and wear it in a pendant or other accessory (for purchase separately) if you choose. Customers give this fitness tracker high marks all around saying it’s simple to use, lightweight and a great way to stay motivated.

Customers say it’s comfortable, easy to understand and is a fantastic daily watch, no matter what activity you set out to conquer.

A bit different from traditional bands that are worn on the wrist, this waterproof fitness tracker is designed to be worn as a headband.

It’s also equipped with a running coach that provides workout data instantly and will track the quality of your sleep too.

It also has a built-in heart monitor, GPS tracking and provides notifications from your phone. The battery lasts up to three weeks in standard mode and up to five hours with the GPS on and music playing. Customers say updates make this version better than those that have gone before, and that it’s an overall great fitness tracker, particularly if you don’t want to have to carry your phone too.

Fitness trackers are a great way to get kids motivated to move as they can see just how much progress they’re making on any goals they set.
