Also, you are in the same place while running on a Treadmill. So the GPS also does not helpful in tracking the distance.

The Customer Watchdog conducted a study on Fitness Trackers and smartwatches and found that most of the fitness trackers and smartwatches not tracking treadmill workouts accurately. The readings were inaccurate because most of them were holding their hands on the treadmill bar.

So make sure to move your hands freely while doing treadmill activities for more accurate date. See the short video here. See her hand movements.

By keeping this mind, let us discuss some important features that you should consider while buying an activity tracker for treadmill running. Otherwise, you may need an ankle activity tracker for more accurate data on treadmill exercise.

Fitness Tracker Buying Gude for Treadmill Run Tracking

If you are looking for a treadmill fitness tracker, then you must keep the following points in mind. This will help you in choosing the best product based on your needs.

Design and Build

Probably the first thing that you consider while selecting a fitness tracker or smartwatch is its style and built. If you need more accurate step counting, then you must choose an advanced fitness tracker or ankle fitness tracker rather than choosing a clip-on style fitness tracker.

You must also consider the strap material. Try to choose a fitness tracker with a rigid and quality built strap.


If you like large display then there is nothing wrong in selecting Fitness band with a large display for your indoor workout. If you choose a fitness tracker with a larger display, then it will be very easy for you to see the data and other notifications displayed on your fitness band.

However, most people prefer to have a lightweight fitness tracker during a workout to avoid any distractions. Then Fitbit Inspire HR will be a good pick for them.


If you are looking for a fitness band with features like GPS and in-built music storage, then you must have a very good budget. Most of the basic trackers do not have both these features. By saying that, carrying a mobile during physical activity is also not recommended as it will distract you a lot.

In such a situation, I recommend you to go for smartwatches with in-built music storage and GPS tracking. Apple Watch 5, Garmin Forerunner series has these features.


You must also look for battery specifications for the battery life of your fitness tracker. You must choose a fitness tracker that gives a battery back-up for at least five hours for an uninterrupted workout section.

Also, you should remember to choose a fitness tracker with a USB Charging port if you do not want to carry your charger every time. Most of the latest fitness trackers and Fitbit bands are coming with a USB charging port so that you can charge the device by connecting it to your laptop or power bank.


Make sure you are buying a fitness tracker that is compatible with your smartphone. There are some fitness trackers that work only either with Android or iPhone.

To avoid this mistake, make sure that the device you are going to purchase is compatible with your smartphone.


It is very important to consider your budget before you buy a fitness tracker or smartwatch. Make sure you are buying a fitness tracker that does not create a hole in your pocket.
