Although research has shown that regularly engaging in vigorous activity has both physical and mental benefits, including a more positive evaluation of one's own body, the multidimensional nature of people's body attitudes has not been considered. The Body Esteem Scale (BES) was developed to identify and assess different body esteem dimensions. Three subscales for women measure sexual attractiveness, weight concerns, and physical condition. Adult females (n=24), ranging in age from 25 to 47 and enrolled in a 12-week aerobic exercise program, completed the Weight Concern and Physical Condition subscales of the BES at the beginning and end of the program. The results indicated that the women's attitudes toward their bodies became more positive on the physical condition dimension of body esteem but not on the weight concern dimension. These results are consistent with previous research (Franzoi and Herzog, 1986) and demonstrate the importance of using multidimensional body esteem measures when investigating the effect that exercise has on body attitudes.
