Watching your heart rate during exercise lets you know when you're in fat burn, cardio or peak zones so you know how hard you're working. The more you can comfortably push yourself, the more benefits you'll see for your heart.

When you work out harder, you deserve more credit. Active Zone Minutes tracks the time you spend in your target heart rate zones, giving you double minutes when you're in cardio or peak. We do the math and show you if you're hitting the recommended 150 minutes each week.

Note: Based on recommendations of the World Health Organization and American Heart Association.
