Active Zone Minutes helps you work out more efficiently and unlock better health
Because activity looks different for everyone, Fitbit developed Active Zone Minutes to help you understand how your activity contributes to your overall health, beyond the number of steps you take.
With Fitbit’s PurePulse® 24/7 heart rate tracking, Active Zone Minutes uses your personalized heart rate zones to track your effort for any energizing activity, whether doing a HIIT workout, power yoga or taking a vigorous walk outside. Earn credit for each minute of moderate activity in fat burn zone and double the credit for vigorous activity in cardio and peak zones – Active Zone Minutes does the math for you so you can quickly understand how many you need to reach your daily and weekly goals. Get real-time alerts on your wrist each time you change zones so you can push harder or scale back to make your workouts more efficient. After a workout, see a detailed summary of your heart rate zones in the Fitbit app, including progress toward your goals, so you can continue challenging yourself to make every minute count.
Active Zone Minutes is based on recommendations from leading health organizations, including the World Health Organization and the American Heart Association, who recommend getting 150 minutes of moderate or 75 minutes of vigorous activity each week, which has been linked to better overall health and well-being, disease prevention, improved cognitive function, less anxiety, and better sleep.5

Sleep better and achieve your goals with Charge 4
Sleep is a critical component to maintaining overall health and wellness and boosting immunity. As such, Fitbit’s leading sleep features are included with Charge 4 to help you understand and improve your sleep. Previously only available on Fitbit smartwatches, smart wake (coming soon) uses machine learning to wake you at the optimal time.
