The independent variables were age, work period, and the frequency of exercise. The dependent variable was the physical fitness calculated by ergocycle during the medical check-up. The data analysis was done descriptively and the correlation test was done by the Chi-Square and Fisher’s Exact Test. Result: In this research, some employees were older than 30 years old (54.5%), male (98.2%), have working period longer than 3 years (65.6%), have normal-day working system (76.4%), performing exercises for at least 3x per week (56.4%), and had a good physical fitness (78.2%).
