@Cazz1977: Hi there. I hope you're well, and enjoying your new Galaxy Watch 3. Sadly there isn't a native option on the device to measure wheelchair pushes, however there are a few things you can try in order to measure your workout effectively. What I'd suggest is heading to the Samsing Health app on the watch > Rotate the bezel to access the exercise tracker, and select 'Workout' > Tap the 3 dots next to the repetitive exercise type, or tap More Workouts to find an option that best suits the situation > Workout Screen. From here you can set a rep counter which, depending on the selected workout, may be able to monitor each push you do with beeping and voice guidance, so you can track your reps instead of steps. If you choose the Step Tracker then this can still monitor the distance traveled, allowing you to set targets for when you're out with your mum. I understand that this isn't ideal, but I hope this goes some way to help you get the most out of the watch.
