The ideal physique for men that is portrayed in the media is a lean and muscular physique, particularly upper body muscularity. The desire to obtain this ideal physique has resulted in increased body dissatisfaction within men. High levels of body dissatisfaction may result in a specific drive for muscularity wherein a man holds attitudes that muscularity is crucial to attain; this attitude is often accompanied by extreme body change behaviors aimed at increasing muscularity. Drive for muscularity is associated with low self-esteem, exercise dependence, eating pathology, and substance abuse (e.g., anabolic steroids, dietary supplements). Information on the psychological risk and maintenance factors of drive for muscularity is sparse. Furthermore, body composition is believed to be an important factor in the drive for muscularity; body mass index (BMI), a simple height-to-weight ratio is most often used, followed by fat-free mass index (FFMI; e.g., the amount of body weight attributable to muscle), and finally body fat percentage. BMI has been associated with general body-image disturbance in men, but this measure of body composition is limited because it does not account for weight attributable to muscle---a key factor in the drive for muscularity. Thus, it is unclear which measure of body composition (e.g., BMI, FFMI, body fat percentage) is most useful in understanding the physique-related aspect of drive for muscularity. This is critical to understand because whether drive for muscularity is related to actual or perceived degree of muscularity (similar to the question of actual vs. perceived thinness as it relates to the drive for thinness in women) remains equivocal.

520 $a This study's objective was to identify the psychological and body composition predictors of drive for muscularity. To achieve this, 113 men completed psychological (e.g., self-esteem, exercise dependence, eating pathology, substance abuse) and body composition (e.g., BMI, body fat percentage, FFMI) measures. Multiple regression analysis was conducted to determine the psychological and body composition measures that were most predictive of drive for muscularity. The results indicated that drive for muscularity is predicted by weightlifting, supplement use, exercise dependence, and self-esteem; however, none of the body composition measures predicted drive for muscularity. Future research efforts should focus on clarifying the role of body composition in drive for muscularity and on developing interventions that target behaviors (e.g., exercise, supplement use) that are associated with drive for muscularity.
