The specific operation steps are as follows:

1. Find the "Healthy Activities" application icon on the home screen, and then click to open it.

2. Next, it depends on the progress of our healthy activity circle that day. At this point, press the screen hard to activate ForceTouch pressure sensing.

3. Then, you can see the option of "Change the campaign target" and click Continue.

4. For example, my current activity goal is to consume 750 calories a day, which can be adjusted by pressing+or-or adjusting the number crown on the screen.

5. After adjusting to the target we want, just click the red "Update" button.

Because AppleWatch has ForceTouch pressure sensing, there are many operation options hidden behind it, and you need to press hard on the screen to see the operation options.
