The importance of exercise is well-known, as are its effects on physical and mental health. It leads to a reduction in the risk of heart disease, diabetes, and depression, and increases psychological well-being. Exercise improves certain domains of life, such as reducing stress, improving sleep and mood, which reflects on overall life satisfaction. It also increases satisfaction with appearance through changes in fitness and strength, and enhances awareness of physical abilities. Furthermore, it improves self-esteem through physical changes and increased self-efficacy. The primary aim of this study was to determine whether there are differences between people who exercise and those who do not in terms of life satisfaction, physical appearance satisfaction, and self-esteem, as well as to identify differences in these variables concerning exercise frequency. The research was conducted via an online survey on a sample of 269 participants. The results showed that there was no statistically significant difference in life satisfaction and self-esteem between those who exercise and those who do not. However, there was a statistically significant difference in satisfaction with physical appearance, with those who exercise being more satisfied with their appearance compared to those who do not exercise. Furthermore, data analysis regarding the frequency of exercise showed that people who exercise regularly and moderately often have greater satisfaction with their appearance than those who exercise rarely, while differences in life satisfaction and selfesteem were not statistically significant. These results suggest that exercise is related to satisfaction with physical appearance, but not necessarily overall life satisfaction or self-esteem. Future research should focus on a more detailed analysis of specific aspects of exercise, such as the type and intensity of activity, as well as the use of specific self-esteem scales related to the physical domain.
