Exercising program is conceived in such a way to make examinees lose the surplus of the fat tissue after an experimental treatment, which includes monitoring of the changes in body mass, percentage of the fat tissue and skin folds. The aim was to establish whether there was any difference in percentage of the fat tissue. The research included 80 female examinees, 20-24 years of age. All examinees were students of the University of Novi Sad (Faculty of Medicine, Faculty of Law, and Faculty of Philosophy) not taking any sports or regular exercising in fitness clubs. As experimental treatment, we used the model of exercising with progressive load. The load was made with free weights and simulators, and according to the station method. The complete program was realized in Fitness Club 'Gym tonic' in SPENS. Exercising lasted three months, three times a week. The estimation of the initial and final state of examinees was performed in the laboratory for functional diagnostics of the Faculty of Medicine in Novi Sad. By means of electrical impedance 'OTRON BF 300' we measured the fat tissue in the body, and in such way we defined the share of the fat tissue in the total body mass. Body mass was measured with decimal scales. As for the skin folds we measured the following: Triceps (skin fold on upper arm), Abdominal (skin fold on stomach area), Skin fold of the thigh. The program was successfully realized, and the measuring variables in experimentally group were reduced comparing to the control group. Body mass was reduced for 1.8 kg on average, and the average value of skin fold of upper arm was reduced for 3.6 mm, skin fold on stomach was on average reduced for 3 mm and the value of the skin fold on the thigh was reduced for 8.1 mm.
