Poor acquired skills in student-athletes are a global concern. This study aimed to determine the significance of endurance and engagement in a computer-based fitness program as predictors of the performance skills acquisition. Employing a predictive research design and using simple random sampling in selecting the 150 junior high school student-athletes, results showed that with a combined degree of 47.8%, both predictors significantly predict the criterion variable. Hence, Com-B Theory is affirmed. Future research may explore other variables not covered in this study to account for the 52.2% variance in performance skills acquisition. Improving resource allocation for fitness programs, integrating gamified strategies, and adopting evidence-based training methodologies is encouraged.
