The purpose of this study was to analyze the impact of service quality in Pilates studios on the revisitation of elderly women, and subsequently verify regional differences. To achieve this, data were collected from 202 elderly women (88 from Gyeonggi and 114 from Gwangju), and the collected data were analyzed according to the research objectives. The following conclusions were drawn. Firstly, it was found that responsiveness, reliability, and tangibility factors in the service quality of Pilates studios for elderly women have a significant impact on revisitation. Secondly, in the verification of regional differences, there were regional variations in the impact of responsiveness and tangibility factors on revisitation, with Pilates studios in the Gyeonggi region showing a relatively high correlation. As a result, for the revisitation of elderly women, the study suggests that Pilates equipment and facilities, high-quality exercise services, and the attitude of instructors are crucial. Moreover, in regions with higher income levels, the Pilates studio environment and the attitude of instructors play a more significant role in encouraging revisitation among elderly women. Therefore, stakeholders focusing on silver Pilates programs are advised to make efforts to maintain an optimal exercise environment and a positive attitude, especially in affluent regions
