About VO2 Max. Estimates
VO2 max. is the maximum volume of oxygen (in milliliters) you
can consume per minute per kilogram of body weight at your
maximum performance. In simple terms, VO2 max. is an
indication of athletic performance and should increase as your
level of fitness improves. The fēnix device requires wrist-based
heart rate or a compatible chest heart rate monitor to display
your VO2 max. estimate. The device has separate VO2 max.
estimates for running and cycling. You can pair your device
with a compatible power meter to display your cycling VO2
max. estimate.
Your VO2 max. estimate appears as a number and position on
the color gauge.

Recovery Time
You can use your Garmin device with wrist-based heart rate or a
compatible chest heart rate monitor to display how much time
remains before you are fully recovered and ready for the next
hard workout.
Recovery time: The recovery time appears immediately
following an activity. The time counts down until it is optimal
for you to attempt another hard workout.

Recovery Heart Rate
If you are training with wrist-based heart rate or a compatible
chest heart rate monitor, you can check your recovery heart rate
value after each activity. Recovery heart rate is the difference
between your exercising heart rate and your heart rate two
minutes after the exercise has stopped. For example, after a
typical training run, you stop the timer. Your heart rate is
140 bpm. After two minutes of no activity or cool down, your
heart rate is 90 bpm. Your recovery heart rate is 50 bpm (140
minus 90). Some studies have linked recovery heart rate to
cardiac health. Higher numbers generally indicate healthier
hearts.
TIP: For best results, you should stop moving for two minutes
while the device calculates your recovery heart rate value. You
can save or discard the activity after this value appears.
