Timed to the launch of its Fitness+ service, Apple has also launched some new features for the Apple Watch.
Starting with iOS 14.3 and watchOS 7.2, the Apple Watch will monitor a user’s cardiorespiratory fitness levels.
Prior to this update, the Watch measured VO2 max (the maximum amount of oxygen the body can use during exercise, typically a measurement of someone’s fitness level), but only for average and higher levels. Now, Apple Watch will also estimate lower levels, giving less active users a more complete picture of their overall fitness.
