Objective: The present study aimed to examine the bright and dark sides of motivation, based on self-determination theory, as predictors of enjoyment, intention to continue exercising, and exercise persistence. In addition, we analyzed the mediation role of each variable and tested the model invariance between male and female exercisers. Methods: A total of 575 gym exercisers (female = 230) aged between 18 and 65 years (M = 34.07; SD = 11.47) participated in this study. All participants had at least 6 months of regular exercise practice; exercise frequency of the participants ranged from 2 to 7 sessions per week (M = 3.52; SD = 1.28) and training sessions lasted approximately 30 and 120 minutes (M = 61.54; SD = 17.64). Participants completed a multisection questionnaire assessing interpersonal behaviors, basic psychological needs satisfaction and frustration, behavioral regulations, enjoyment, and intentions to continue exercising. Exercise persistence was assessed 6 months after initial assessment using gym computer system attendance records. Several analyses, namely, confirmatory factor analysis, structural equation modeling, serial mediation analysis, and structural invariance testing, were performed to increase theoretical and empirical knowledge. Results: Positive associations were observed among the bright side of motivation, enjoyment, intention to continue exercising, and persistence. On the other hand, the dark side of motivation was negatively associated with the bright side constructs, enjoyment, intention, and exercise persistence. Both measurement [χ2(370) = 1496.708, χ2/df = 4.05; B-S P < .001, CFI = 0.907, TLI = 0.901, SRMR = 0.056, RMSEA = 0.073 (CI 90% = 0.063, 0.083)] and structural models [χ2(393) = 2484.994, χ2/df = 6.323; B-S P < .001, CFI = 0.908, TLI = 0.900, SRMR = 0.075, RMSEA = 0.071 (CI 90% = 0.067, 0.075)] displayed acceptable fit to the data. The results also showed that basic psychological needs satisfaction, autonomous motivation, enjoyment, and intention to continue exercising were significant mediators. However, enjoyment had the highest effect on exercise persistence. In addition, structural model invariance was confirmed between male and female exercisers. Conclusion: Motivational determinants have implications for predicting emotional, cognitive, and behavior-related outcomes. Individuals should perceive exercise
