Buddhist qigong
Buddhism has qigong. When the founder of Dharma saw that the monks in Shaolin Temple seldom exercised while meditating, but practiced sick Zen, he taught them Yijinjing and washing marrow qigong. In the Han Buddhism, there are few body postures, but there are many hidden secrets, such as "Shake", "Aquarius", "Stupid Fire Six-Day Body Posture", "Spirit Fire Method" and "Sakya Six Styles".

Sorry, tantric qigong is different from ordinary qigong. This is a kind of qigong. You must convert to the guru and then be enlightened by the guru before you can practice. This is because the pulse involved is not quite the same as that of the ordinary Qijing Eight Pulse and the twelve meridians. And blindly practicing will make mistakes, so you must have the guidance of a Taoist priest to avoid making mistakes.

Practice Tai Ji Chuan, and you are less likely to make mistakes.
