• Training in certain heart rate zones can help you improve
cardiovascular capacity and strength.
If you know your maximum heart rate, you can use the table
( Heart Rate Zone Calculations , page 17 ) 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.
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.
Setting Your Heart Rate Zones
The device uses your user profile information from the initial
setup to determine your default heart rate zones. You can set
separate heart rate zones for sport profiles, such as running,
cycling, and swimming. For the most accurate calorie data
during your activity, set your maximum heart rate. You can also
set each heart rate zone and enter your resting heart rate
manually. You can manually adjust your zones on the device or
using your Garmin Connect account.

threshold heart rate.
You can perform a guided test to estimate your lactate
threshold ( Lactate Threshold , page 16 ). You can use the
Auto Detection feature to automatically record your lactate
threshold during an activity ( Detecting Performance
Measurements Automatically , page 13 ).
5 Select Resting HR , and enter your resting heart rate.
You can use the average resting heart rate measured by your
device, or you can set a custom resting heart rate.

• Select
BPM to view and edit the zones in beats per
minute.
• Select %Max. HR to view and edit the zones as a
percentage of your maximum heart rate.
• Select %HRR to view and edit the zones as a percentage
of your heart rate reserve (maximum heart rate minus
resting heart rate).

heart rate and set your heart rate zones as a percentage of your
maximum heart rate.
• Verify that your user profile settings are accurate (
Setting Up
Your User Profile , page 16 ).
• Run often with the wrist or chest heart rate monitor.
• Try a few heart rate training plans, available from your
Garmin Connect account.
• View your heart rate trends and time in zones using your
Garmin Connect account.

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.

Activity Tracking
The activity tracking feature records your daily step count,
distance traveled, intensity minutes, floors climbed, calories
burned, and sleep statistics for each recorded day. Your calories
burned includes your base metabolism plus activity calories.
The number of steps taken during the day appears on the steps
widget. The step count is updated periodically.

accuracy, go to garmin.com/ataccuracy .
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 .
