Studies have shown the role of exercise in promoting mental health and fostering positive emotions. This study proposes the assessment of the psychometric properties of the Reasons for Exercise Inventory (REI). A sample of 206 physical exercise practitioners (mean age 27.31 years ± 8.01, 50% women) answered the instruments. The fit indices of different measurement models employed for the REI in the literature were compared through Confirmatory Factor Analysis. Reliability and its correlation with the state of mindfulness during exercise were estimated. The results indicated a better fit for the model composed of seven factors (reasons for exercise): weight control, fitness, mood, health, attractiveness, enjoyment and tone, all with good reliability indicators. Moderate positive associations between mindfulness indicators and intrinsic reasons for exercise: mood and enjoyment were observed. It was concluded that the Brazilian version of the REI is an adequate measure of the reasons for exercise, corresponding to the original version.
