In the Fitbit app, tap the Today tab and tap your profile picture.Instead of using these 3 heart-rate zones, you can create a custom zone to target a specific heart rate:
In the peak zone, you’re likely doing a short, intense activity that improves performance and speed such as sprinting or high-intensity interval training. Greater than 85% of your heart rate reserve In the cardio zone, you’re likely doing a vigorous activity such as running or spinning. Your heart rate and breathing might be elevated, but you can still carry on a conversation.īetween 60% and 84% of your heart rate reserve In the fat burn zone, you’re likely in a moderate activity such as a brisk walk. You’re at rest for now.īetween 40% and 59% of your heart rate reserve Iconīelow the fat burn zone, your heart beats at a slower pace. Personalized zones adjust as your fitness level or other factors change. *Occasionally during intense exercise, you might notice your heart rate go above your Fitbit-calculated maximum heart rate. Note that you can see your personalized heart-rate zones on the Active Zone Minutes screen in the Fitbit app. Next, use your heart rate reserve to calculate your personalized heart-rate zones. (Percentage of maximum heart rate × heart rate reserve) + resting heart rate By lowering your resting heart rate, you can increase your heart rate reserve.įor example, if you are 45 years old and your resting heart rate is 74 bpm, here’s the math:įirst, calculate your maximum heart rate and heart rate reserve. While your maximum heart rate is generally determined by age, your resting heart rate can be lowered by increasing your fitness level. Heart rate reserve is an indication of your overall cardiovascular fitness. Air temperature and certain medications can also affect resting heart rate.įitbit personalizes your heart-rate zones using your heart rate reserve, which is the difference between your maximum heart rate* and your resting heart rate ( source).
Several factors can affect resting heart rate: stress, alcohol or caffeine intake, or fever usually raise resting heart rate, while regular exercise or meditation can lower it.
