Why Do Women Exercise? Factor Analysis and Further Validation of the Reasons for Exercise Inventory

This investigation examined the factor structure and correlates of the Reasons for Exercise Inventory among 101 exercising women. Subjects completed the 24-item inventory (with one added item), reported their weekly frequency of exercise, and completed two standardized body-image measures. Factor analysis indicated that, with minor modifications, the instrument has an internally consistent structure with four factors of Appearance/Weight Management, Fitness/Health Management, Stress/Mood Management, and Socializing. Appearance/Weight Management was associated with a more negative body image independent of actual body mass and was the only motive related to self-reported frequency of exercise.
