Low physical activity and high prevalence of sedentary lifestyles are a significant global health problem among adolescents, with long-term consequences in the form of an increased risk of non-communicable diseases. In Alang-Alang Lebar District, Palembang City, this problem emerged with data showing that 65% of adolescents spent more than 4 hours per day on digital activities and 29% were overweight to obese. This study aims to evaluate the effectiveness of the "Basic CrossFit Training" program in improving physical fitness and healthy lifestyle awareness in adolescents in the region. Using a Community-Based Participatory Action approach, this study involved adolescents aged 13–20 years in an intensive training program for 4 weeks (8 sessions), which was complemented by ISBN modules, digital video tutorials, and movement guide posters. The design of this study is a quasi-experiment with pre-test and post-test to measure changes in knowledge and technical mastery of movements. The results of the data analysis showed a significant increase in health knowledge, with the average score increasing from 58.3 to 82.7. In addition, 89% of participants managed to master the basic CrossFit movement techniques correctly, and most importantly, there were no injuries during training. Beyond physical metrics, the program successfully built an independent fitness ecosystem that was adopted by two local schools and is planned to be replicated in other districts. These findings suggest that community-based Basic CrossFit interventions, supported by simple educational technologies and local capacity building, are an effective and sustainable strategy to address adolescent health crises in resource-constrained environments. The program is not only aligned with Sustainable Development Goals (SDGs) 3, 4, and 11, but also offers a replication model that is relevant to similar contexts in Indonesia and other developing countries.
