Last August, I wrote in “Another Good Trend” that my cardio fitness levels, as reported by my Apple Watch through the Health app, had gone from “below average” to “above average.” Cardio fitness is Apple’s term for VO2 max. From the Health app:

This is a measurement of your VO, max, which is the maximum amount of oxygen your body can consume during exercise. Also called cardiorespiratory fitness, this is a useful measurement for everyone from the very fit to those managing illness.

A higher VOz max indicates a higher level of cardio fitness and endurance.

Oddly, all of the rowing I do doesn’t lead to Cardio Fitness reports. But walking does. Rhonda and I took the dogs for a 30-minute walk again today and I found a pleasant update when I checked my stats: I moved into the “high” category.
