This paper reflects the results of a study on the motivational factors of practicing fitness by men in the Republic of Moldova. Starting from the data from the specialized scientific-methodical literature, as well as from the results of their own observations, a sociological survey was developed (15 questions), which was applied to a group of 40 men who attend various fitness clubs in Chisinau. The study highlighted a number of aspects, the most important being the following: the profile of the subjects; general aspects of their fitness); the reasons that determine them to practice fitness, according to the three categories: related to physical condition, psycho-emotional and cognitive sphere, socio-professional sphere, in order to determine the dominant motivational factors, those of increased importance and those of low importance; the degree of subjects satisfaction after practicing fitness; the role it assigns to fitness trainer/instructor in obtaining their results. The model for determining the motivational factors of practicing fitness by men can be proposed for application to coaches in fitness centers in our country, which would help maintain a constant interest of the population and, implicitly, to streamline the fitness training process.
