Tracks daily totals for past 30 days Stores heart rate data at 1 second intervals during exercise tracking and at 5 second intervals all other times\n\nBuying Guide\n\nMove it up: Since blood increases further up your arm, wear your tracker higher on your wrist to improve the heart rate signal during workouts. Start by moving the device up to three finger widths above your wrist bone, then experiment with slightly lower placement. Keep it secure: The less your tracker moves during exercise, the more chance you have of maintaining a heart rate signal throughout the activity. Do not wear the band too tightly, as this can restrict blood flow and goes against our wear and care guidelines. Hold steady for ten seconds: High intensity exercises or activities that cause you to keep your wrist bent (like push-ups) or move your arms vigorously (like dance) may interfere with heart rate signals. If you stop seeing a signal during these types of activities, hold your wrist steady for ten seconds during breaks to get your reading.\n\nManufacturer Contact Information\n\nCustomers contact: support@fitbit.com
