If you're worried about it, maybe try to find a class or a meetup event, or something like that in order to get it from a person. Many people use that method exclusively and it's nothing to feel any sort of way about, it's effective. Alternatively, there are books and videos and different ways to teach yourself.

If you're looking for a practical book about the internal side of qigong (also called energy work), Robert Bruce's book
