Why should you care about VO2 Max? Again, this is a very relevant metric if you use your Apple Watch as part of your fitness journey. If you are interested in optimizing your health, you need to track and improve your VO2 Max score. This is because it can have a significant impact on your overall health and risk of death. Peter Attia, health influencer and MD, says:

“Simply lowering VO2 max from ‘low’ (lower 25th percentile) to ‘below average’ (25th to 50th percentile) was associated with a 50% reduction in all-cause mortality. Moving from ‘low’ to ‘above average’ (50th to 75th percentile), the risk reduction approaches 70%!”

VO2 Max is important because there are not many other interventions that can significantly reduce the risk of death from all causes. Let’s take a look at how you can view this information on your Apple Watch.

    Your VO2 Max score may change daily based on your exercise, activity level, and other fitness data. When observed with Apple Watch, VO2 max scores were significantly higher on running days compared to walking days. This is not surprising considering that one day has a much higher cardio load than another.

    Note: If you haven’t yet set up cardio fitness on your iPhone and Apple Watch, open the Health app to access your VO2 Max information and you’ll see a series of steps to set up cardio tracking instead. Select “Settings” and follow the instructions to check your health information (age, gender, weight, etc.) and whether you want to turn on ‘low-cardio fitness’ notifications. Once you’ve set up your cardio fitness, you’ll need to go on several outdoor walks, runs, or hikes to calculate your cardio fitness and VO2 Max scores.

    This is a really useful feature for tracking your fitness level. While it can be useful to see averages and information about your VO2 Max, it’s also important to remember that you’re ultimately competing against yourself here and whether you want to improve your VO2 Max score.

This is where it can be useful to look at your target heart rate zones since you are typically exercising in higher target heart rate zones. VO2 Max improves.

    There are other ways to calculate your VO2 Max, or more roundabout ways to estimate it (like the Cooper Test), but thanks to the Apple Watch and iPhone, you can now get this data in your Health app and track changes and progress. With your fitness journey.
