Setting Your Power Zones

The values for the zones are default values based on gender,
weight, and average ability, and may not match your personal
abilities. If you know your functional threshold power (FTP)
value, you can enter it and allow the software to calculate your
power zones automatically. You can manually adjust your zones
on the device or using your Garmin Connect account.

Auto Goal

Your device creates a daily step goal automatically, based on
your previous activity levels. As you move during the day, the
device shows your progress toward your daily goal
If you choose not to use the auto goal feature, you can set a
personalized step goal on your Garmin Connect account.

Using the Move Alert

Sitting for prolonged periods of time can trigger undesirable
metabolic state changes. The move alert reminds you to keep
moving. After one hour of inactivity, Move! and the red bar
appear. Additional segments appear after every 15 minutes of
inactivity. The device also beeps or vibrates if audible tones are
turned on (System Settings, page
Go for a short walk (at least a couple of minutes) to reset the
move alert.

Sleep Tracking

While you are sleeping, the device automatically detects your
sleep and monitors your movement during your normal sleep
hours. You can set your normal sleep hours in the user settings
on your Garmin Connect account. Sleep statistics include total
hours of sleep, sleep levels, and sleep movement. You can view
your sleep statistics on your Garmin Connect account.
NOTE: Naps are not added to your sleep statistics. You can use

Intensity Minutes

To improve your health, organizations such as the World Health
Organization recommend at least 150 minutes per week of
moderate intensity activity, such as brisk walking, or 75 minutes
per week of vigorous intensity activity, such as running.
The device monitors your activity intensity and tracks your time
spent participating in moderate to vigorous intensity activities
(heart rate data is required to quantify vigorous intensity). You
can work toward achieving your weekly intensity minutes goal by
participating in at least 10 consecutive minutes of moderate to
vigorous intensity activities. The device adds the amount of
