In China Wushu, sitting on a horse and standing on a pile are often practiced at the same time, mainly to make the muscles of the whole body tense, so as to consciously control each group of voluntary muscles and semi-voluntary muscles, and the qi needs to sink into the abdomen (concept point). In modern terms, it is abdominal breathing. Try to pull down the diaphragm and tighten the lowest part of the abdominal muscles, and feel that the gas in the body has reached the abdomen.

Soft qigong

Buddhist meditation, Taoist health exercises (and modern soft exercises) all belong to this category. There is no need to tighten muscles. Pay attention to take a deep breath and let it have no distractions. The China Wushu Wing Chun Boxing of Taiji Slow Preaching and Nanquan School, the first set of boxing ideas in the initial introductory practice, belong to this category. Soft qigong can not only enhance vital capacity without consuming a lot of physical strength, but also exercise all muscles, including semi-voluntary muscles in the human body and (passively) move internal organs, so it is suitable for all kinds of people to practice. Especially suitable for the elderly, women and patients who can't exercise a lot.

I hope it helps you.
