The relevance of the study is based on the fact that the health status of school children has recently deteriorated markedly, and one of the ways to combat this and improve overall well-being is through physical exercise. The purpose of the study is to provide a detailed analysis of the author's "Sport in Square" course. The methods of research used in the study include the functional method, the method of logical analysis, the method of synthesis, the method of deduction, the method of induction, and others. The study analysed the various components of the author's methodology. Thus, it was noted that the uniqueness of the course is that it provides people with the opportunity to exercise in a limited space, the exercises target different muscle groups and, importantly, help to improve the condition of various body systems. A rather remarkable feature of the course is that for each level a link to the YouTube platform is attached, which the course participant can download once and use whenever they want. In addition, this author's "Sport in square" course is unique in that it is designed for mass physical activity and exercise for all ages and all fitness levels. Notably, it can develop muscular, cerebral, coordination, logic and thinking skills. The practical value of the results is that using the author's course in general educational institutions will further improve the general health of schoolchildren.
