What is cardio fitness?
Apple defines it as “a measurement of your VO2 max, which is the maximum amount of oxygen your body can consume during exercise.” The Apple Watch measures how hard your heart works during a long outdoor walk, run, or hike and gives you the cardio fitness estimate, which is a valuable indicator of overall physical and long-term health. You can learn more via Apple’s official press release.
How Apple Watch records your cardio fitness levels?
Your Apple Watch uses the on-device heart and motion sensors during a strenuous physical activity like an outdoor walk, run, or hike to estimate your VO2 max. Your age, sex, height, weight, and heart affecting medications are also considered for preparing this data.
Which Apple Watch models and watchOS versions support cardio fitness?
To set up cardio fitness, you need the following:
- Apple Watch Series 3, 4, 5, 6, or SE updated to watchOS 7.2 or above.
- iPhone updated to iOS 14.3.
Note: It can take several workouts (excluding Push workouts) and more than 24 hours before you get your first cardio fitness level estimate.
