Notifications options for sharing

Hi there StanleyG.,

Thanks for posting your question! As we understand it, you want to know if it's possible to share your Activity details but disable the notification about completing a workout. That's a great question, and we're happy to provide some information that might help.

This resource, Share your Activity and compete with friends with your Apple Watch, may be worth reviewing:

"Start sharing

To share activity, you and your friends both need an Apple Watch. When your friends close their rings, finish workouts, or earn achievements, you get notifications about their progress."

You might try this:

"Hide your progress

1. Open the Activity app on your iPhone.
2. Tap the Sharing tab, then tap the friend that you want to hide your activity from. 
3. Tap Hide my Activity. You can still see your friend's activity, but they won't see your activity. You can't hide your activity from a friend that you're competing with.
4. To start sharing again, tap Show my Activity."

If that isn't quite what you're looking for, you can always use this link to send your suggestion to Apple: Product Feedback

Kind regards.
