Introduction

Fitbit has a range of fitness bands designed to get you up and running, or jogging, or swimming, or whatever you want to do. You can track your heart rate with Fitbit and determine if you're burning calories with heart rate zones.
Before You Begin:
You must have the Fitbit App installed.

1 How to Wear My Fitbit for Optimal Heart Rate Tracking

Proper Tightness

Tighten 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.

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
    Out of zone heart rate icon 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
    Fat burn icon 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
    Cardio Zone iconBetween 70% and 84% of maximum heart rate. Medium-to-high intensity exercise zone. Pushing yourself but not straining.
    Peak Zone
    Peak heart zone iconGreater than 85% of your maximum heart rate. High-intensity exercise zone. Good for short intense sessions that improve performance and speed.
