Qigong and taiji qì gōng · tài jí · 气功与太极

Movement, breath and attention practised together — either for health maintenance or as a martial art. In English-language research it is usually studied as a gentle physical activity; trials most often look at balance, fall prevention in older adults, and quality of life.

That framing is a normal exercise-science one and does not require any claim about Qi. It is generally low-risk and adaptable — a large part of why it travels well across cultures.
