1. Introduction: This study investigates the relationship between the physical activities of adults living in rural areas and each component of the Transtheoretical Model. Methods: This descriptive and relational study was conducted with 315 individuals at a rural clinic in Turkey. Data were collected using tools for evaluating the Transtheoretical Model, and the International Physical Activity Questionnaire. Logistic regression analysis, multiple regression analysis, and path analysis were used in statistical analyses. Results: Of the individuals living in rural areas, 59.1% were inactive, and 42.4% of the individuals were in the precontemplation stage. The mean exercise self-efficacy score was low, and pros subdimension of decisional balance was at an insufficient level. According to path analysis, perceived self-efficacy and stage of change for exercise were the variables that had a significant effect on physical activity (the metabolic equivalent of task score). Conclusion: The Transtheoretical Model is a strategic approach to improving exercise behavior in rural areas, and the prerequisites of health promotion such as enhancing education, income, and opportunities will contribute to the popularization of exercise.
