This study aimed to verify the factorial and internal validity of the Brazilian version of Exercise Motivation Inventory-2 (EMI-2) and compare the main reasons for exercise training considering the contexts of health clubs and personal training. A total of 588 exercisers of Pelotas city / RS / Brazil (405 from health clubs and 183 from personal training) filled the EMI-2, which consists of 51 items grouped into 14 motives (factors) for exercise. The factorial validity of the EMI-2 was tested by conducting confirmatory factorial analyzes and the internal validity by computing Cronbach's alpha. To verify the effect of the context on the motives it was used the MANOVA test and calculated the effect-size. The results obtained support the EMI-2 original structure of 14 factors in this sample. There was a significant mul-tivariate effect of the context on the motives for exercising [Wilks' λ = 0.912, F(14, 573.000) = 3.9, p < 0.001, η² = 0.088]. The motives of "Pleasure", "Strength and Endurance", "Challenge", "Socialization", "Competition" and "Social Recognition" were significantly higher in the context of health clubs and the motives of "Agility" and "Prevention of Diseases" were significantly higher in the context of personal training.
