Hi E M. Great question. Please click on your profile icon in the upper right corner and select "My Profile". Once on this screen, you can click the tab for "Watched" to see all the videos that you've previously watched. Or you may click the tab for "I Did This" to see the videos that you've watched and claimed the "I Did This". This tab will also show you any external activities you've tracked (from Apple Watch, Garmin, or Fitbit) or any of the "Daily Workouts" you've done.
