20 12 The core part of the popular fourth set of happy dance aerobics consists of 7 sections and 49 movements, 7 tracks, and the music duration is 50 minutes. The arrangement of the whole set of movements is more novel and reasonable, and the fitness effect is more scientific and effective.

By the end of 20 12 and 10, many fitness teams and training teams had adapted Happy Dancing Exercises and produced many new sets. However, most of them are based on the original seven paragraphs, plus some self-created actions. Some are composed of eight segments for 60 minutes (7+ 1 mode) and some are composed of 1 1 segment for 80 minutes (7+4 mode). In view of the fact that most of the participants are middle-aged and elderly people, seven 50-minute "happy dance aerobics" are more reasonable and scientific. In this way, "Jiamusi Happy Dance Step" was adopted in the first seven paragraphs of aerobics in various places, and the movements in the last few paragraphs were selected by the teachers from the original "Aerobics March" and created by the group, so the music and movements of many fitness teams were different from the eighth paragraph, and even incorporated yangko or hip-hop elements.
