OBJECTIVE: To test the theory of planned behavior (TPB) in aerobic versus resistance training in a prospective design. Relationships between TPB variables, extroversion, and perceived health were examined. METHODS: College students (210) completed an initial measurement and a 3-month follow-up assessment. Reasons for exercising were assessed. RESULTS: TPB variables, extroversion, and perceived health collectively accounted for substantial variance in aerobic (19%) and resistance exercise (40%). Reasons for exercise included physical, psychological, and social concerns. CONCLUSION: Differences in the predictive validity of model constructs suggest potential differential intervention foci for aerobic versus resistance exercise.
