Updating the exercise circles on Apple Watch ⌚️

Hi I stupidly went out a cycle and forgot my watch. The workout was recorded on the Strava app on my iPhone so all the data from the workout is somewhere on my iPhone. To my disappointment when I put my watch on there was no syncing and the workout info didn’t change my activity circles on my watch. I think this should have happened automatically but didn’t. Is there a way to fix this?
