Due to the increasing incidence of obesity, it is very important to raise people's awareness of the importance of physical activity. The focus should be on all those negative consequences that obesity entails, from serious health problems to impairment of the quality of life. Through this thesis, the influence of eight-week training on the morphological characteristics of an individual is presented. The paper explains in more detail the specific type of training processes, the so-called functional training that is often practiced in fitness. Functional training is designed to mimic activities and movements so that the adaptations caused by training are more applicable. The subjects on whom this research was conducted were women, members of a local fitness club from the Imotski area, aged 25 to 50. For eight weeks, they performed functional training three times a week. Each training session was adapted to the age group, the needs of the test subjects, previous physical activity, but also their state of health. In accordance with the set goals of this work, the results of the research confirmed the set hypotheses, namely that after the eight-week functional training, there were differences in the changes in the measured dimensions of the test subjects, while there were no significant changes in the body composition of the test subjects.
