You can now use the Apple Watch to track core training, dance, functional strength training and cool down workouts.
This means you won’t get to enjoy the new features on the original Apple Watch from 2015, as well as Apple Series 1 and Series 2.
Only for Apple Watch Series 3 and above Unlike iOS 14 which supports older devices like the iPhone 6s from 5 years ago, the new watchOS 7 is only compatible for the Apple Watch Series 3 and above.
For the first time, Apple now supports Sleep Tracking for the watch.
In order to measure your dance workout, the Apple Watch combines data from the heart rate sensor along with inputs from the accelerometer and gyroscope.
