One hundred five older adults enrolled in exercise classes were recruited from local YMCAs. Exercise behavior was measured 1, 3, and 9 months after beginning the exercise class. Intentions were not a significant predictor of exercise behavior, probably because of a lack of variance; most people intended to exercise. The direct measures of attitudes, subjective norms, and perceived behavioral control, however, explained 9% of exercise behavior at 1 month. They did not significantly explain behavior at 3 and 9 months. When the indirect measure of subjective norms explained 18% of exercise behavior at 1 month. The indirect measure of perceived behavioral control accounted for 27% of the variance at 1 month and 10% at 3 months.
