Stand.
Sitting less can improve your health. So Apple Watch senses when you stand and move. The Stand ring closes when you’re up for at least one minute in 12 different hours during a day.
Move.
Apple Watch suggests a goal each week for how many active calories to burn based on your recent history. Adjust it up or down until it feels just right. The Move ring closes when you meet the daily goal.
“Hey Siri, have I closed my Move ring today?”
Exercise.
Any activity at the level of a brisk walk or above is exercise. The Exercise ring closes when you reach the recommended 30 minutes per day — and you don’t have to do it all at once.
