Wear a compatible Apple Watch regularly, including overnight, and allow access to the health data you want to use. Watch workouts and other features depend on compatible devices and software. Your score supports training decisions: consider it alongside how you feel. Training Today does not provide medical advice, diagnosis or treatment.
