Objective Pathological exercise is common among those with eating disorders and has typically been characterized as excessive, compulsive, or compensatory in nature. Little is known about how pathological exercise is associated with other eating disorder behaviors or personality traits, or whether these associations differ between men and women. Method We used hierarchical dimensional modeling in three samples, including college women ( N = 205), women with eating psychopathology ( N = 268), and college men ( N = 235), to examine latent associations between pathological exercise and eating disorder psychopathology, namely compulsivity, emotion regulation, and body dissatisfaction. Results Using Goldberg's (2006) “bass‐ackwards” method, we identified separate 10‐factor solutions (women) or an 11‐factor solution (men). A distinct muscle building factor arose in the three‐factor solution for men, and it also notably arose in the six‐ and eight‐factor solutions for community and college women, respectively, highlighting an important understudied motivation factor in both healthy and pathological exercise. Each solution accounted for 64.8% (college women), 51.9% (women with eating psychopathology), and 43.9% (college men) of the variance in excessive exercise, respectively. Discussion Findings indicate that pathological exercise is associated with different psychological traits (e.g., poor emotion regulation, compulsivity) across populations, and such differences may necessitate unique treatment approaches tailored accordingly.
