When I open Samsung Health on my phone I have various workouts that I've found through the app that I'm tracking. I can select to start a workout and it will go through it on my phone but when I'm done, it just says Circuit Training 19 minutes in the Exercise area. No other information, like calories burned, is available. If I start a Circuit Training exercise on my watch, it will record it just fine but if I record it on my watch AND watch the video, it records as two separate workouts.
