Learn how to set up Cardio Fitness on Apple Watch

Another valuable health feature has been added to iPhone and Apple Watch with iOS 14.3 and watchOS 7.2 – Cardio Fitness. The measurement is based on your VO2 max which Apple Watch can estimate when recording certain workouts. Follow along for a look at how to use Cardio Fitness on iPhone and Apple Watch including why it’s important, how to set it up, and how to measure/view Cardio Fitness levels.

Here’s how Apple describes Cardio Fitness levels:

With iOS 14.3 and watchOS 7.2, Apple Watch users can view their cardio fitness level in the Health app on iPhone, and receive a notification on Apple Watch if it falls within the low range. Breakthrough technology released in watchOS 7 allows Apple Watch to easily measure low cardio fitness, and today cardio fitness notifications empower users to be more active for dramatic long-term health benefits.

Cardiorespiratory fitness, as measured by VO2 max, is the maximum amount of oxygen the body can use during exercise, and it can be increased through physical activity. Apple Watch already estimates average and higher levels of VO2 max during vigorous outdoor walks, runs, or hikes, which many runners and other athletes monitor to improve performance.

Essentially, Cardio Fitness is one metric that gives an indication of overall health and can also predict long-term health. While there’s a correlation between low Cardio Fitness levels and future health issues, you’ve got the power to raise your levels with consistent aerobic exercise.
