China Wushu can strengthen the body, mainly from the second source. This is also a bad statement, but at present I think this statement is basically in line with the facts. Then this question is transformed into: What are the main similarities and differences between Taoist health preservation and modern fitness? The fundamental difference lies in the different development time. Taoist health preservation has developed for thousands of years, and the guiding ideology is relatively high so far; However, the guiding ideology of modern fitness is too mechanical and rigid because of its short time, weak foundation and little knowledge. But modern fitness is based on modern science and technology, and it is still summing up experience and developing rapidly. The future is limitless. However, the teaching of Taoist health preservation is too personalized to be popularized. Now it seems to be gradually declining. In the future, perhaps the modern body-building techniques we are exposed to now will be as well respected as Taoist body-building techniques in a thousand years.
