Apple fitness not sharing

Hey tomfor2,

We'd recommend reviewing the information in this article as it provides options and requirements for sharing a Fitness+ subscription with family: Subscribe to Apple Fitness+ - Apple Support

"Share your Apple Fitness+ subscription with Family Sharing

When you subscribe to Apple Fitness+ or Apple One Premier, you can use Family Sharing to share your subscription with up to five other family members. Your family group members donʼt need to do anything—Apple Fitness+ is available to them the first time they open the Fitness app after your subscription begins, as long as they have an Apple Watch Series 3 or later. If a family member has an Apple Watch, but no iPhone (because their Apple Watch was set up by a family member), they can still use Apple Fitness+ with Apple TV or with an iPad.

Note: To stop sharing your Apple Fitness+ subscription with a family group, you can remove a member from a Family Sharing group. See Add or remove Family Sharing members in the iPhone User Guide."

If that's not working as expected, we'd recommend contacting Apple Support for assistance here: Apple Support

Thanks!
