Reaching the recommended activity guidelines

Active Zone Minutes counts your time spent in any heart-pumping activity. Your default goal is based on the widely accepted recommendation of 150 minutes of moderate activity or 75 minutes of vigorous activity per week.*

Work out smarter

With Active Zone Minutes, the harder you work, the more credit you get. 1 minute in the fat burn zone earns 1 Active Zone Minute, and 1 minute in the cardio or peak zone earns 2 Active Zone Minutes. You put in the work, and we’ll do the math!

A focus on personalization

Your target heart rate zones are personalized based on your age and resting heart rate, giving you a more accurate understanding of how to optimize your effort.

Zone notifications keep you in the know

When you’re in an exercise mode, your Fitbit tracker or watch** buzzes to let you know when you enter and exit a heart rate zone: 1 buzz for the fat burn zone, 2 buzzes for the cardio zone and 3 buzzes for the peak zone.
