@Kitty44: Please be aware that not all exercise types are represented on the Galaxy Watch range. If you head to the Samsung Health app on the watch > Swipe upwards or downwards > Open the exercise tracker screen > Work out, you can check the available options here. For additional options, tap on 'More workouts'. If you can't see Inline Skating here, I recommend choosing a category that closely resembles it, so you can track the the relevant data.
