We’ve translated your cardiorespiratory fitness level into a more relatable number—your Fitness Age. This tells you how your cardiorespiratory fitness compares to other adults of your sex. This is not a fixed number, simply a reflection of where you are currently at. It is calculated using your resting and active heart rate, your age, sex, height and weight.
Improve or maintain your Fitness Age by earning PAI. Challenge yourself to be more active and you’ll see the impact on your Fitness Age.
You can use the projection graph on the Fitness Age screen to predict how your Fitness Age will change over the next few months, based on your PAI Score.
Remember, your Fitness Age is tied to health benefits, maintaining a PAI Score of 100 or more is proven to reduce risk of cardiovascular disease by an average of 25% and increase life expectancy by an average of 5 years.
