Chunyi Lin in the video for Level 1 is shown doing the active exercises outdoors. It looked like some type of botanical garden. I practiced outdoors in woods behind my house. It's very early spring in Pennslvania where I live. Everything was very fresh and refreshing. The surroundings were a spring forest. I enjoyed it tremendously and plan to do the active exercises from Levels 1 and 2 outdoors in the woods when I have the opportunity.
