Cardio fitness is a vital metric tracked by the Apple Watch, offering insights into your cardiovascular health. However, there might be instances when you want to reset this metric due to various reasons, such as recalibrating after significant changes in your fitness level or troubleshooting issues. This article will provide a comprehensive, step-by-step guide on how to reset cardio fitness on your Apple Watch.
Understanding Cardio Fitness on Apple Watch

How Apple Watch Measures Cardio Fitness
The Apple Watch estimates your cardio fitness level using various sensors and data points, including heart rate, GPS, and activity data. It calculates VO2 max when you engage in specific workouts like outdoor walking, running, or hiking.
Reasons to Reset Cardio Fitness
There are several reasons why you might want to reset your cardio fitness data:
Recalibration: After significant changes in your fitness routine or physical condition.
Troubleshooting: If the readings seem inaccurate or inconsistent.
Personal Preference: To start tracking anew from a specific point.
