2. How to Wear My Fitbit for Optimal Heart Rate Tracking
Proper TightnessTighten the band just enough so it isn't slipping around on your wrist. Your tracker needs a solid contact with your arm to reliably track your heart rate. Heart rate tracking may not work with certain accessory bands, especially if they’re loose fitting. Fitbit recommends wearing their classic or sport bands during exercise.
Picking the Right Position
Tracking is better when the fitness band is in the right spot. Move the band to a slightly different position on your arm. Just a little higher or a little lower.
3. Setting Up My Fitbit to Read My Heart Rate
You can easily set up your Fitbit to read your heart rate either from the App or the website.
Using Your Fitbit App
Open the Fitbit app on your mobile device.
Click on the Account icon.
Choose your device from the list.
Tap on Heart Rate Tracking and make sure it is set to Auto.
Using the Fitbit Website
If your Fitbit device isn't displaying your heart rate, follow the steps below. After each step, check your device to see if your heart rate is being displayed again.
Click the gear icon in the top right corner, then select Settings.
Select Devices.

This will show your current heart rate and either your heart-rate zone or resting heart rate (if not in a zone).
What Are Heart Rate Zones?
Heart-rate zones help you target the training intensity of your choice. Default heart-rate zones are calculated using your estimated maximum heart rate.
Fitbit calculates your maximum heart rate with the common formula of 220 minus your age.
The heart icon you see above your current heart rate tells you your zone. Refer to the following for an explanation of the different heart rate zones.
Out of or No Zone
Your heart rate is below 50% of your maximum heart rate and may be elevated but not enough to be considered exercise.
Fat Burn Zone
Between 50% and 69% of your maximum heart rate. This is a low-to-medium intensity exercise zone. It's called the Fat Burn Zone because a higher percentage of calories are burned from fat, but the total calorie burn rate is lower.
Cardio Zone
Between 70% and 84% of maximum heart rate. Medium-to-high intensity exercise zone. Pushing yourself but not straining.
Peak Zone
Greater than 85% of your maximum heart rate. High-intensity exercise zone. Good for short intense sessions that improve performance and speed.
