However, as with any technology, some users have reported that this nifty feature doesn’t always work as expected.

But fret not, fellow Fitbit fans!

In this blog post, we’ll delve into the possible causes, troubleshoot the problem, and discuss best practices prevent Fitbit from not auto recognizing exercise.

So, let’s dive in and get your Fitbit back on track 🙂

Troubleshooting Fitbit Auto Exercise Recognition Issues

Fitbit’s SmartTrack is designed to automatically recognize and log different types of physical activities.

This convenience helps users track their progress without the hassle of manually inputting data.

Follow the steps below to fix your Fitbit not auto recognizing exercise issue:

1. Basic Troubleshooting Steps

When faced with an issue, it’s essential first to try some basic troubleshooting steps.

Here’s what you can do:

a. Log out of the Fitbit app, force quit it, and restart the device.

b. Turn off Bluetooth and shut off your phone for 1-2 minutes before turning it back on.

c. Temporarily change the time setting for auto-detected exercise, save the changes, and then restore the original time setting.

2. Wear Your Fitbit The Right Way

One of the most common reasons for auto-detect exercise not working is improper wear of the device.

Here’s how to ensure accurate heart rate detection and a better overall experience:

a. Make sure the smartwatch is in contact with your skin.

b. Avoid wearing the device too loose or too tight. It should be snug but comfortable.

3. Check Exercise Duration and Intensity

Your Fitbit needs to recognize specific parameters to auto-detect an exercise.

Keep these points in mind:

a. Auto-detect exercise works when the heart rate is above a certain BPM for 10 minutes or more.

b. If the heart rate is not high enough during the exercise, the device may not recognize it.

4. Update the Fitbit App

Running an outdated version of the Fitbit app can cause data syncing issues and prevent the auto-detect feature from working correctly.

To avoid these problems:

a. Make sure you are running the latest version of the Fitbit app.

b. Regularly check for updates and install them as soon as they’re available.

5. Restart and Reset the Device

If you’ve tried everything else and the issue persists, it might be time to take more drastic measures:

a. Restart your Fitbit fitness tracker and recalibrate it if necessary.

b. Reset the device to its factory settings if other troubleshooting steps fail.

6. Contact Fitbit Customer Support

If all else fails, don’t hesitate to reach out to Fitbit customer support for further assistance.

Best Practices for Accurate Exercise Tracking

Now that we’ve tackled the troubleshooting aspect, let’s focus on some best practices to ensure accurate exercise tracking with your Fitbit device.

To ensure accurate exercise tracking, consider implementing the following best practices:

1. Manually Log Exercises

If your Fitbit device doesn’t auto recognize an activity, log it manually in the Fitbit app.

This ensures that your exercise data is recorded and factored into your daily and weekly progress.

To manually log an exercise:

  1. Open the Fitbit app on your smartphone.
  2. Tap on the “Exercise” tile.
  3. Click on the “+” button in the top-right corner.
  4. Select the type of exercise, input the activity’s details (such as duration, distance, or calories burned), and tap “Log.”

2. Customize Exercise Shortcuts

Add exercise shortcuts to your Fitbit device for easy access to your favorite workouts.

This allows you to start tracking a specific exercise manually, ensuring accurate data collection.

To customize exercise shortcuts, follow these steps:

  1. Open the Fitbit app on your smartphone.
  2. Tap on the profile icon in the top-left corner.
  3. Select your Fitbit device from the list.
  4. Find the “Exercise Shortcuts” option and tap on it.
  5. You can now add, remove, or rearrange exercises in your shortcuts list.

3. Use Connected GPS For Outdoor Exercises

The connected GPS feature on your Fitbit device provides more accurate distance and pace data for outdoor activities by leveraging your smartphone’s GPS capabilities.

To use connected GPS:

  1. Ensure your phone is nearby and the Fitbit app is running in the background during your workout.
  2. Start an outdoor exercise on your Fitbit device (e.g., running or biking).
  3. Your device will then use your phone’s GPS data to track the workout more accurately.

4. Always Ensure Your Device Is Sync With The Fitbit App

Regularly syncing your Fitbit device with the app not only ensures that your data is up-to-date but also helps keep the device’s software current.

This can help prevent issues with exercise recognition and tracking.

To sync your device:

  1. Open the Fitbit app on your smartphone.
  2. Ensure your Fitbit device is nearby and within Bluetooth range.
  3. Swipe down on the app’s dashboard to initiate the syncing process.

5. Re-calibrate The Device

Calibrating your Fitbit device can improve the accuracy of distance and step tracking.

To calibrate your device:

  1. Open the Fitbit app on your smartphone.
  2. Tap on the profile icon in the top-left corner.
  3. Select your Fitbit device from the list.
  4. Find and tap on “Personal Stats.”
  5. Input your stride length, height, weight, and other personal information.

6. Cross-reference With Other Tracking Methods

To verify the accuracy of your Fitbit’s exercise tracking, occasionally cross-reference the data with other tracking methods.

You could do so by using smartphone apps, GPS watches, or even manual measurements (e.g., using a known distance or a stopwatch).


Auto-detect exercise is a fantastic feature for Fitbit users, making it easy to track various physical activities without manual input.

By following the troubleshooting steps and best practices outlined in this blog post, you can resolve any issues with exercise recognition and ensure your Fitbit accurately tracks your workouts.

Fitness tracking should be a seamless part of your daily routine, and with these tips, you’ll be well on your way to a better Fitbit experience.
