The article examines the issue of motivation of women in the first period of adulthood regarding recreational aquafitness classes. Motivation is a psychophysiological process that, under the influence of external or internal factors, stimulates people's desire to engage in this or that activity. Aquafitness classes are one of the main factors in slowing down the aging process, maintaining health and increasing physical activity. Only a few scientific studies have been found that highlight the specifics of aqua fitness classes with women in the first period of adulthood. The question of the priority motives of women in the process of health training and the importance of taking them into account when planning during physical exertion is considered. Women in the first period of adulthood participated in the study (n=60). One of the questions of the questionnaire was to determine the motivational priorities of women in the first period of adulthood for aquafitness classes. Thus, the majority (70.1%) of the interviewed women are not satisfied or partially satisfied with their own bodies, women sought to improve their girth measurements, namely: waist – 86.8%, hips – 78.5%, buttocks – 70.1%. The level of physical fitness of women according to their own subjective feeling is: 40.1% - lower than average, 36.7% - average and 13.4% - low. Based on the results of the questionnaire, the motivational priorities of women in the first period of adulthood for recreational aquafitness classes were determined. It should be noted that our research correlates to some extent with other research on the features of motor activity of adult women in their free time. These results are the reason for developing a program of aquafitness classes using a differentiated approach with a selected contingent of women according to their body types and body mass index indicators.
