Stress fractures are bone injuries due to overuse, which depletes bone tissue and causes tissue discontinuity. Regular physical activity and adequate rest periods can reduce these risk factors, as the bones become stronger with muscle strength. This study aimed to determine the relationship between BMI and pre-military training activities on the risk of stress fractures. The research adopted analytic observational using a retrospective approach. This research uses a cross-sectional design and a total sampling technique to obtain a sample size of 36 participants. The chi-square test was used for data analysis. Data collection was conducted through observation sheets and the GPAQ version 2 questionnaire, facilitating the acquisition of relevant information. The results showed an effect of BMI in stress fracture incidence with p value=0,347 and OR 4 (95% CI 0,56-28,39). There was also an effect in pre-basic military training exercise in stress fracture incidence p value=0,637 and OR 2,5 (95% CI 0,37-16,88). Risk factors that influence and increase the risk of stress are physical exercise with a duration of 25 hours/week, which causes the body to experience an overtrained condition that affects BMI on the incidence of stress, and pre-military training on the incidence of stress fractures
