With the development of economy and the improvement of people's living standards, more and more elderly people and women are beginning to pay attention to their health and join the ranks of fitness. For this group, it is obviously impossible to adopt the same fitness methods as adult men. Sports such as swimming and badminton require a certain amount of energy and physical strength. If you exercise without energy and physical strength, it is easy to have sports injuries. In addition, with the accelerated pace of life, the pressure on office workers is increasing, often because of lack of energy and physical strength. In order to achieve better fitness effect, people began to pay attention to some low-intensity exercise methods and fitness equipment, such as yoga, Pilates, Tai Ji Chuan, sitting exercise bike and so on. Compared with the traditional high-intensity, competitive and antagonistic exercise methods, they have lower exercise intensity and no confrontation, emphasizing physical and mental health, which is the so-called "gentle fitness" method.

In the United States, Pilates, Yoga and Sitting Bike have become popular fitness programs since the late 1990s. According to the research of ASD (American Sports Data Company), 26% of Americans said they felt "great pressure" in their lives. Yoga emphasizes relaxation of body and mind at the same time, so the number of participants in yoga increased greatly from 1998 to 2002. By 2002, there were1165438+million participants, of whom 83% were women. In China, yoga, Pilates and other "moderate fitness" methods are gradually accepted by more people.
