<![CDATA[This study aimed to develop and evaluate the effectiveness of an Aero Boxing training model designed to improve the physical fitness of Indonesian Air Force personnel. The study was motivated by the need for innovative training methods to address declining physical fitness levels among military personnel, as reflected in physical fitness test results that frequently fall below the required standards. This research employed a Research and Development (R&D) approach using the ADDIE model, which consists of Analysis, Design, Development, Implementation, and Evaluation stages. The participants were active personnel from Denmabesau who participated in the development and field-testing phases of the program. Data were collected through physical fitness assessments, observations, and questionnaires. The effectiveness of the model was evaluated using pretest–posttest measurements and statistical analysis. The results demonstrated that the Aero Boxing training model significantly improved cardiovascular endurance (VO₂Max), muscular strength, agility, and participants’ motivation to engage in physical training. Paired-sample t-test analysis revealed significant differences between pretest and posttest scores (p < .05), while N-Gain analysis indicated moderate to high effectiveness across all measured variables. These findings suggest that the Aero Boxing training model is a valid, practical, and effective training innovation for enhancing military physical fitness. Therefore, the model can be recommended as an alternative conditioning program to support physical readiness and operational performance among Indonesian Air Force personnel.]]>
