Hi
When you first set up the Activity app, Apple Watch suggests an initial daily Move goal (an active calories / kilojoules target), which reflects your personal information (age, gender, height and weight) and general activity level.
On Monday of each week, the Activity app provides a Weekly Summary via the Notification Centre on your watch. At the foot of the summary, a new Move goal may be suggested based on your previous performance, along with the option to adjust the goal.
The Move goal can also be changed at any other time:
- Open the Activity app on your watch:
- When viewing the time on your watch face, tap on the Activity rings icon / complication.
- Or go the Home screen (via a single press of the Digital Crown, when viewing the time on your watch) and tap on the Activity app icon (coloured rings).
- Press firmly on the screen > tap on Change Move Goal > change the goal.
