Because of the economic development and living standard enhancement, the Taiwanese people's life expectancy has increased. With that comes the concern for good health during the longer life. Health clubs generally provide people a climate controlled facility with a variety of equipment and the availability of professional or trained personnel to facilitate safe use of facilities offered. In USA membership in health clubs increased 51% in the decade of the 1990s. In Taiwan membership in health clubs is also growing. The respondents' demographic background, decision-making, recognition, marketing preferences and willingness to participation in the health clubs will be included in the survey and their relationship will also be analyzed. This study surveyed 346 respondents. The results show that respondents of different demographic background have different decision-making, recognition, marketing preferences and willingness to participation in the health clubs. Moreover, the respondents' decision-making, recognition, marketing preferences cause their willingness to participation in the health clubs. The findings of this research are to be presented to people in the health club business and to government agencies concerned with health, fitness and small business development.
