minutes. Your total vigorous intensity minutes are doubled when
added.
Earning Intensity Minutes
Your Forerunner device calculates intensity minutes by
comparing your heart rate data during an activity to your
average resting heart rate. If heart rate is turned off, the device
calculates moderate intensity minutes by analyzing your steps
per minute.
• Start a timed activity for the most accurate calculation of
intensity minutes.
• Exercise for at least 10 consecutive minutes at a moderate or
vigorous intensity level.
Sleep Tracking
While you are sleeping, the device monitors your movement.
Sleep statistics include total hours of sleep, sleep levels, and
sleep movement. You can set your normal sleep hours in the
user settings on your Garmin Connect account. You can view
your sleep statistics on your Garmin Connect account.

About Heart Rate Zones
Many athletes use heart rate zones to measure and increase
their cardiovascular strength and improve their level of fitness. A
heart rate zone is a set range of heartbeats per minute. The five
commonly accepted heart rate zones are numbered from 1 to 5
according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
Fitness Goals
Knowing your heart rate zones can help you measure and
improve your fitness by understanding and applying these
principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve
cardiovascular capacity and strength.
• Knowing your heart rate zones can prevent you from
overtraining and can decrease your risk of injury.
If you know your maximum heart rate, you can use the table
(
) to determine the best
heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the
calculators available on the Internet. Some gyms and health
centers can provide a test that measures maximum heart rate.
The default maximum heart rate is 220 minus your age.
Setting Your Maximum Heart Rate
The device uses your user profile information from the initial
setup to estimate your maximum heart rate and determine your
default heart rate zones. The default maximum heart rate is 220
minus your age. For the most accurate calorie data during your
activity, you should set your maximum heart rate (if known).
