Check your heart rate

Luxe personalizes your heart-rate zones using your heart rate reserve, which is the difference between your maximum heart rate and your resting heart rate. To help you target the training intensity of your choice, check your heart rate and heart-rate zone on your tracker during exercise. Luxe notifies you when you enter a heart-rate zone.

Heart-rate zones help you target the training intensity of your choice. Three zones based on American Heart Association recommendations are available, or you can create a custom zone if you have a specific heart rate you're targeting.

Default heart-rate zones

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.

Icon	Zone	Calculation	Description
	Below Zone	Below 50% of your maximum heart rate	Below the fat burn zone, your heart beats at a slower pace.
	Fat Burn Zone	Between 50% and 69% of your maximum heart rate	In the fat burn zone, you’re likely in a moderate activity such as a brisk walk. Your heart rate and breathing might be elevated, but you can still carry on a conversation.
	Cardio Zone	Between 70% and 84% of your maximum heart rate	In the cardio zone, you’re likely doing a vigorous activity such as running or spinning.
	Peak Zone	Greater than 85% of your maximum 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.

Custom heart-rate zones

Instead of using these heart-rate zones, you can create a custom zone in the Fitbit app to target a specific heart-rate range.

Earn Active Zone Minutes

Earn Active Zone Minutes for time spent in the fat burn, cardio, or peak heart-rate zones. To help you maximize your time, you earn 2 Active Zone Minutes for each minute you’re in the cardio or peak zones.

1 minute in the fat burn zone = 1 Active Zone Minute
1 minute in the cardio or peak zones = 2 Active Zone Minutes

There are 2 ways Luxe notifies you about Active Zone Minutes:

• A few moments after you enter a different heart-rate zone during your exercise using the Exercise app , so that you know how hard you’re working. The number of times your tracker vibrates indicates which zone you’re in:

1 buzz = fat burn zone
2 buzzes = cardio zone
3 buzzes = peak zone

• 7 minutes after you enter a heart-rate zone throughout the day (for example, during a brisk walk).

Heart-zone notifications are turned off to start. To turn them on:

• Heart-zone notifications during exercise in the Exercise app—see Track and analyze exercise with the Exercise app
• Heart-zone notifications during everyday activity—see Adjust settings

To start, your weekly goal is set to 150 Active Zone Minutes. You’ll receive notifications as you reach your goal.
