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 cardiovascular strength and
should increase as your level of fitness improves. The
D2 Air X10 watch requires wrist-based heart rate or a
compatible chest heart rate monitor to display your VO2
max. estimate.
On the watch, your VO2 max. estimate appears as
a number and description. On your Garmin Connect
account, you can view additional details about your VO2
max. estimate.

Viewing Your Fitness Age
Your fitness age gives you an idea of how your fitness
compares with a person of the same sex. Your 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
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.
NOTE: For the most accurate fitness age, complete the

Pulse Oximeter
The D2 Air X10 watch has a wrist-based pulse oximeter
to gauge the saturation of oxygen in your blood. Knowing
your oxygen saturation can be valuable in understanding
your overall health and help you determine how your body
is adapting to altitude. Your watch gauges your blood
oxygen level by shining light into the skin and checking
how much light is absorbed. This is referred to as SpO
On the watch, your pulse oximeter readings appear as
