Fitness Tracker Accessories

Have you bought an activity tracker and want to spice up your workouts with more thorough heart rate monitoring? Get a chest strap, which is a useful fitness tracker accessory that allows you to train more effectively. Other activity tracker accessories include interchangeable wrist bands, such as those for vivofit2 fitness trackers.

Take your workouts to a next level

Garmin or Polar chest straps are quality heart rate sensors that you can pair wirelessly with a fitness tracker or smartphone via Bluetooth. This lets you keep track of your exact heart rate and adjust the workout intensity to maximise the results. Based on your selected data, your fitness tracker can tell you what zone you are currently in. Heart rate monitoring data is saved in the fitness tracker’s memory, allowing you to check average or maximum values.
