Good question and a good concern. Also, welcome to Spring Forest Qigong.
My thoughts are that Master Lin has simplified this form of Qigong so that anyone can do it and receive the benefits, even at home otherwise why would he invest so much time in designing a home study course.
I came to SFQ so that I could be more proactive about my health, I have no nor had no prior major illness except for anxiety and stress. So what I wanted to have is more peace of mind and calmness through the day. I can say that I have received that and so much more. Everyday aches and pains are gone or diminishing and I actually feel ten years younger. (I'm almost 40)
I would also add that one shouldn't dismiss testimonials that are truthful. They are real stories of regular people.
I always tell people that their OWN experience is the best test. I hope that you will try Spring Forest Qigong and KNOW for yourself. There are plenty of people here on this board who can answer questions that come up during home practice so you are really not all alone in your study.
Take care
JEFF
