watch uses information, such as your age, body mass
index (BMI), resting heart rate data, and vigorous
activity history to provide a fitness age. If you have
a Garmin Index scale, your watch uses the body fat
percentage metric instead of BMI to determine your
fitness age. Exercise and lifestyle changes can impact
your fitness age.

Heart Rate Variability and Stress Level
Stress level is the result of a three-minute test
performed while standing still, where the Enduro device
analyzes heart rate variability to determine your overall
stress. Training, sleep, nutrition, and general life stress
all impact how a runner performs. The stress level
range is from 1 to 100, where 1 is a very low stress
state and 100 is a very high stress state. Knowing your

This feature requires a Garmin chest heart rate monitor.
Before you can view your heart rate variability (HRV)
stress level, you must put on a heart rate monitor and
pair it with your device (

TIP: Garmin recommends that you measure your stress
level at approximately the same time and under the
same conditions every day.

Performance Condition
As you complete your activity, such as running or
cycling, the performance condition feature analyzes
your pace, heart rate, and heart rate variability to
make a real-time assessment of your ability to
perform compared to your average fitness level. It is
approximately your real-time percentage deviation from
your baseline VO2 max. estimate.
Performance condition values range from -20 to +20.
After the first 6 to 20 minutes of your activity, the
device displays your performance condition score.
For example, a score of +5 means that you are rested,
fresh, and capable of a good run or ride. You can add
performance condition as a data field to one of your
training screens to monitor your ability throughout the
activity. Performance condition can also be an indicator
of fatigue level, especially at the end of a long training
run or ride.
NOTE: The device requires a few runs or rides with
a heart rate monitor to get an accurate VO2 max.
