The increasing prevalence of Diabetes Mellitus (DM) requires comprehensive management that integrates pharmacological therapy with lifestyle modification and physical activity. Diabetes exercise is a complementary intervention that can improve glucose utilization, blood circulation, physical fitness, and glycemic control when performed regularly. However, many individuals with DM and those at risk of developing DM still have limited knowledge, motivation, and skills to perform diabetes exercise correctly and consistently. This community service program aimed to provide education and training on diabetes management and introduce safe, correct, and sustainable diabetes exercise to community members at the Cina Community Health Center, Bone Regency, South Sulawesi. The program involved 38 participants, consisting of 20 individuals with DM and 18 individuals in the high-risk group. The activities were conducted through three stages: planning and preparation, training implementation, and monitoring and evaluation. Interactive lectures, demonstrations, direct practice, pre-tests, and post-tests were used to assess participants’ knowledge and skills. The results showed an improvement in participants’ understanding of diabetes, the benefits of diabetes exercise, and the correct exercise movements, accompanied by improved ability to practice the movements independently. Although some participants, particularly older adults, experienced difficulties memorizing the exercise movements, they demonstrated high enthusiasm throughout the activities. An instructional diabetes exercise video was also distributed through the participants’ social media group to support independent practice at home. The program is expected to encourage regular physical activity, improve healthy lifestyle behaviors, strengthen participants’ self-management skills, and support the establishment of sustainable community-based diabetes exercise groups.
