The system of health fitness has been operating only for 20 years in Ukraine. Our state adopts the cult of a healthy lifestyle, which is why a huge number of fitness clubs have appeared. Organizational aspects of the health fitness system of Ukraine have not been studied sufficiently. The goal of the work is to improve the organizational support of the health fitness system in Ukraine. Fitness clubs are an important segment in the development of health motor activity. It is necessary to create relationships inside and outside the organization for the effective functioning of fitness clubs. The purpose of the organizational support of the fitness club is to support the response to changes in the external environment and the adaptation of the internal environment to these changes by providing the necessary resources, organizing the relationships between individual elements, and eliminating deviations that may occur. We have determined the factors of the microenvironment and the macroenvironment for the organizational support of the health fitness system. There was assessed the importance of the impact of each factor. This gives an understanding of the demand and significance of the professional activity of the fitness staff, the economic possibilities of the development and consumption of the health fitness system services (payability of the population), political stability and the intentions of the authorities regarding the development of society (today, unfortunately, the health fitness system does not interact with state and public management bodies, etc.). The factors of the remote environment also allow us to predict the possibilities of the development of science and technology, to reorient ourselves to promising/innovative fitness technologies in a timely manner. That is why the health fitness system must take them into account, respond in time and adapt to the corresponding changes.
