This study examined the influence of YouTube fitness videos on exercise motivation among civil servants in Edo State, Nigeria. The study adopted the survey research design. The population comprised 45,000 civil servants in Edo State, while a sample size of 381 respondents was determined using the Krejcie and Morgan table. A multi-stage sampling technique was used to select respondents from ministries, departments and agencies across the three senatorial districts of the state. Data were collected using a structured questionnaire, while the reliability of the instrument was established through a pilot study, which produced a Cronbach's Alpha coefficient of 0.89. Data were analysed using frequency distributions, percentages and descriptive statistics, while the study was anchored on Cultivation Theory. The findings showed that respondents had relatively high exposure to YouTube fitness videos and generally perceived the videos as having considerable motivational value for engaging in physical exercise and maintaining healthy lifestyles. However, work schedules, lack of time, internet and data costs, and difficulty maintaining exercise consistency constituted major challenges to translating online motivation into regular physical activity. The researchers conclude that YouTube has considerable potential as a source of fitness motivation among civil servants, but exposure and motivation alone are insufficient to guarantee sustained exercise practices. The researchers recommend workplace fitness programmes, realistic exercise routines that accommodate civil servants' schedules, and the promotion of credible and locally relevant fitness content.
