Independent fitness gyms are less popular now and therefore most of them are operated by fitness gym chains.
Fitness gyms can be divided into three types. The first type is equipped with swimming pool. This gym usually offers swimming school too. The second type is without swimming pool but instructors are located at the gym. The last type has neither swimming pool nor instructor. First and second types also offer classes such as yoga and aerobics. Recently the third type is expanding now and and these gyms are located at residential areas and open 24 hours a day.
The difference between European and Japanese gyms are the member. Majority of members in Japan is seniors but Europe is under 50 years old. Also spinning is not familiar to Japanese.
