Group fitness programs allow people of different anthropological characteristics, levels of preparation, and affinity to apply light, medium and advanced exercise programs in a group. Group exercise programs have a positive impact on body composition, functionality of the locomotor system, cardiorespiratory endurance and the psychological well-being of an individual. Thanks to the wide range of fitness centers, the offers of group exercise programs are increasing, and they have become one of the most popular ways to exercise in today's age. This research was conducted with the aim of examining the impact of different group exercise programs on the anthropometric characteristics, body composition, and the satisfaction of the exercisers. The research was carried out on a total sample of 40 female subjects with an average age of 40, and it was divided into two experimental groups that, during a three-month period, implemented different models of the group exercise program. The first experimental group (n=22) participated in a combined model of group exercise programs, while the second experimental group (n=18) participated in a single model group exercise program. Student's t-test for independent samples was used to determine differences between subjects, and differences in changes were tested using the non-parametric Mann Whitney U test. In order to test the satisfaction of the subjects with the exercise program, an online survey questionnaire was created, and the statistical significance of the differences between them was tested using the Chi-square test and Fisher's exact test. The findings of this research establish statistically significant differences in the changes in morphological characteristics and body composition of subjects under the influence of different group exercise programs and different levels of satisfaction with the selected exercise program. The obtained results show that the combined model of group exercise has a statistically significantly greater impact on changes in anthropometric characteristics such as waist circumference and suprailiocristal skin fold. When examining the level of satisfaction of exercisers, the results of the survey show that the main goals they want to achieve with training are improving and preserving health and increasing muscle mass.
