The current study aimed to investigate the relationships between leader-member exchange (LMX) quality, empowerment, and job performance of fitness center instructors. Data were mainly analyzed using a structural equation modeling technique with the AMOS program. The results, based on a paper-and-pencil survey with 263 respondents from 15 fitness centers, reported that LMX quality positively influences the level of empowerment perceived by subordinates while employee empowerment has a positive effect on job performance. However, LMX quality does not statistically influence self-rated job performance. Employee empowerment mediates the relationship between LMX quality and job performance.
