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
™
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.
NOTE: For the most accurate fitness age, complete the user profile setup (Setting Up Your User Profile,
page41).
1 Hold .
2 Select > User Profile > Fitness Age.
Pulse Oximeter
The Venu Sq 2 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
2
.
On the watch, your pulse oximeter readings appear as an SpO
2
percentage. On your Garmin Connect account,
you can view additional details about your pulse oximeter readings, including trends over multiple days
(Changing the Pulse Oximeter Tracking Mode, page38). For more information on pulse oximeter accuracy,
go to garmin.com/ataccuracy.
