Yoga originated from an ancient Indian country, and in recent years it has become a global health trend, and China is no exception. By analyzing and discussing the background and reasons why yoga was introduced into China, this paper further reveals the essence of yoga, compares the present situation of yoga in China, and puts forward relevant suggestions to promote the healthy development of yoga in China. In the early 1980s, aerobics became popular in various cities in China, and many fitness centers with aerobics as the main content were successively opened in the society. Aerobics began to spread to the society through various media. With the efforts of the State Sports General Administration, the news media and many aerobics workers, the concept of "health" as a fitness guide for women in China has gradually taken shape. Moreover, when choosing fitness exercises, women not only choose aerobics as their first choice, but also yoga and belly dancing have become popular. Among them, yoga is more concerned by people. Therefore, it can be said that yoga was introduced into China as a form of fitness. With the further spread of yoga in China, yoga clothes, books, VCD and other related products appeared immediately, and yoga began to gradually go out of gymnasiums, and gradually established yoga halls, yoga centers, yoga clubs and other relatively professional training places. Therefore, the popularity of yoga in contemporary China presents the characteristics of "fitness". However, with the establishment of "health"-oriented fitness concept, the function of yoga is being reinterpreted by people. The reason why yoga is so popular is that more and more people begin to practice yoga. I think the main reasons are as follows: First, yoga itself shows a kind of formal beauty. It is a gentle exercise, which can make both practitioners and spectators enjoy the beauty, and the arrangement of many movements of yoga can highlight the curve shape of the human body, which is one of the reasons why female friends like yoga. Furthermore, the value of yoga has been proved and recognized, and practitioners hope to relieve psychological stress and achieve physical and mental harmony by practicing yoga. In addition, it satisfies the practitioners' pursuit of novelty and fashion.
