Apple watch and iPhone not syncing Workout infor

The workouts appear under my Apple Watch when I look in the “Devices” section of the Fitness or Watch settings.

However, none of these historic workouts are showing up in the Health app or Fitness app on my iPhone.

I have tried restoring from iCloud and re-pairing the watch, but the data still isn’t syncing properly.

I would really appreciate guidance on how to get my historic workout and health data back into the Health app.

Things I’ve already tried:

Checked that Health is turned on under iCloud sync.

Confirmed both devices are signed in with the same Apple ID.

Ensured Fitness Tracking and Health permissions are enabled under Privacy & Security → Motion & Fitness.

Tried restoring from an older iCloud backup (but it didn’t bring back the workout history).

Apple support tells me this is normal, if so why bother archiving work-outs as they are totally useless if you cannot use them

Question:

How can I import or sync the older workout data stored under my devices on my phone all from Apple Watchs back into the Health app, especially if it goes back several years?
