Warm-ups are a crucial component of physical education, as they prepare students physically and mentally for movement-based activities. However, the implementation of warm-ups in elementary schools often faces challenges, such as limited understanding of static and dynamic warm-up techniques, a lack of activity variety, and a lack of structured application. This community service initiative aims to enhance the understanding and skills of both students and physical education teachers regarding warm-up routines tailored to the characteristics of elementary school children, utilizing an activity-based approach. The program was conducted at SDN 1 Kekait, West Lombok Regency, through a series of stages: outreach, conceptual education, demonstration, hands-on practice, the use of supporting media, mentoring, and evaluation. The implementation strategy emphasized active participant engagement through varied movements and game-based activities, making the warm-up material easier to grasp and more engaging to apply. Supporting materials—including video tutorials, posters or infographics, and digital guides—were utilized to reinforce understanding and ensure program sustainability. The results indicate that the initiative provided students and teachers with practical experience in identifying and applying static and dynamic warm-up routines in a more structured and varied manner. The mentoring process also encouraged teachers to routinely integrate activity-based warm-ups into their physical education lessons. Ultimately, this activity is expected to foster a habit of structured warm-ups as an essential part of physical preparation for students prior to physical education sessions.
