Better Calorie Burn Tracking
Losing, gaining or maintaining weight is about math: calories in vs. out. By measuring how hard your heart is working—both all day and during workouts—you get a better measure of total calories burned.
So, even if your favorite heart-pumping activities don’t affect your step count, you’ll still get the right credit for your effort.
Optimize your time spent on exercise
Tracking heart rate during workouts can help you maintain the right intensity, find a sweet spot for pace or avoid overtraining.
During workouts, use Fitbit’s heart rate zones to gauge how much effort you’re exerting and see if you should dial it up or dial it back. Afterward, check your workout summary in the Fitbit app to view your time in each zone and to follow improvements over time.
