best waterproof fitness tracker

Waterproof fitness trackers are the best option for people who want to track their fitness progress. Some smartwatches have a fitness tracker built in, but more and more fitness enthusiasts are steering away from a smartwatch for their fitness tracking needs. This is due to the fact that smartwatches simply aren’t built to be as resilient as fitness trackers.

Working out involves bumping, sweating, and shaking, all of which will damage most smart watches. All quality fitness trackers are resistant to these, particularly sweat. However, just being able to handle sweat doesn’t make a fitness tracker completely waterproof.

If there is any chance your fitness tracker will be submerged in water, you should consider a waterproof fitness tracker. Waterproof fitness trackers are sealed and submersible. These are the best fitness trackers for swimming as they are completely submersible.

In this guide, we will cover the five best waterproof fitness trackers you can possibly find.
