The Apple Watch expands its range of cardio fitness measurements
See the original posting on The Verge

Apple is expanding the range of cardiorespiratory fitness that can be measured on the Apple Watch. Starting today, the Health app will classify users as having âhigh,â âabove average,â âbelow average,â or âlowâ cardio fitness. Low levels will trigger a notification.
The Watch tracks fitness through a metric called VO2 max, which is the amount of oxygen your body consumes during movement or exercise. The Apple Watch was already tracking average and high VO2 max for users during exercise. This update expands the range it measures and allows users to see their levels when theyâre walking around, not just when theyâre working out.
