Background: Most of today's activities are sedentary, and therefore the person for the preservation of physical and mental health uses various recreational activities.Crossfit allows recreational athletes to endure a high-quality training session in a short period of time, to stop thinking about everyday business issues and maintain their vitality. To prevent injuries among this group, it is necessary to educate them about the techniques of performing certain exercises and raise awareness about the importance and well-being of stretching before and after training sessions. The aim of this study was to determine the changes in the flexibility of the hip and ankle joints by applying static and dynamic stretching in recreational athletes. Subjects and methods: 30 recreational athletes took part in this study. After initial measurement, the participants were randomly divided into a dynamic and static group. The participants were tested in terms of their flexion and external hip rotation, ankle dorsal flexion, while the functional tests included measuring their deep squat ability, knee-to-wall test, and hurdle step test. The program was conducted three times a week, and the respondents were tested again after 4 weeks. Results: The sample, a group with the average age of 28.03 years, has shown positive results after a four-week stretching program within the scope of their recreational activities. By comparing groups, statistical significance was recorded in deep squat tests and knee-to-wall test. Conclusion: The stretching program used in this study can serve as a good method for improving the flexibility of the joints important for a quality squat movement.
