Hi there CorumMc,
Thank you for posting to Apple Support Communities.
We understand you'd like to make sure you're logged in with the correct Apple ID for the Fitness app. Is that correct?
We have some suggestions:
- On your iPhone, check the Contacts app and your contact card. Make sure this has the correct name and email address associated with it.
- Open the Watch app on iPhone and then go to General > About. Make sure your name is listed.
- In General, tap on Apple ID to ensure your Apple ID is signed in.
- In the Health app on iPhone, tap your profile picture at the top-right then tap Health Details. Make sure your name is correct here.
That should help. Let us know if you have any questions.
Take care.
