When I attended the Level 1 class, we did this exercise while sitting in a chair. That was 2 years ago. I usually do it that way, even now. If you want to work on balance, that's fine, but it is not necessary to do it standing up.
For all of the exercises, Master Lin says you can do them standing, sitting, or lying down.
Good luck with your experiences in Spring Forest Qigong!
