It's easy to tell. At present, China's mass aerobics is divided into 1-6 levels, and level 6 is the most difficult, but it will not exceed the level of ordinary people, mainly because of the strength and standardization of movements. If it is a competition, it is necessary to add personal expression, the uniformity of the team and the change of formation. Long-term rigorous practice can also have good results for ordinary people. Competitive aerobics requires more difficult movements and physical fitness. Professional competitive aerobics athletes in China are generally transformed from professional gymnasts. It is difficult for people without foundation to practice. Moreover, it can be slightly distinguished from music: the music rhythm of mass aerobics is fast, but the music rhythm of competitive aerobics is fast, usually there are more than a dozen movements in an eight-beat, while mass aerobics is generally 1 movement, with two movements occasionally, but not much. It should be easy to tell how many times you watch it.
