Sublimation of advanced scientific ideas into the strategy of student youth’s rehabilitation involves the creation and implementation of effective innovative technologies. At the present stage of physical culture and sports field development, in terms of effectiveness of body correction the most recognized are health fitness systems. Objective. The experiment involved 121 female students aged 17–18 with different body types, namely mesomorphs – 64, ectomorphs – 35, endomorphs – 22 individuals (n = 121). Methods. Theoretical ones have been used to study and substantiate the basic provisions of the study, outline its problem field, systematize the scientists’ experience on the issue of female students' physique correction in the process of their physical training, study of modern scientific approaches to the development and improvement of physical education; empirical methods included pedagogical observation; anthropometric examination of female students; body type of students – using the Pinier index. Method of recording and analysis of female students’ body static-dynamic stability (diagnostic and training complex “SportKat 650 TS” on the basis of a movable platform, the degree of mobility of which is adjustable); consistently pedagogical transformative experiment; statistical methods have been applied to process the results of the study. Results of the study. The positive impact of the suggested technology is evidenced by changes in the average values of the circumferential body size of female students with mesomorphic body type: increase in the average values of chest girth (; S) (before: 85.3; 5.50 cm after: 88.2; 4.71 cm), (p <0.01); increase in average values of shoulder girth (before: 26.2; 3.81 cm after: 27.7; 2.19 cm), (p <0.01); decrease in the average values of the circumferential abdomen size (before: 68.1; 5.51 cm after: 66.3; 3.32 cm), (p <0.05); decrease in the average values of the thigh girth (before: 55.0; 3.80 cm after: 53.9; 2.00 cm), (p <0.05). Statistically significant changes have been found in the direction of increasing the average values of the shoulder circumferential size among female students of ectomorphic body type: (; S) (before: 23.3; 3.71 cm after: 24.9; 2.21 cm), (p<0.05); average values of the thigh circumferential size (before: 52.1; 4.94 cm after: 53.9; 2.01 cm), (p<0.05). During the examination of female students of endomorphic body type, we have also observed the improvement (decrease) of the average values of the abdomen girth (; S) (before: 75.4; 4.83 cm after: 72.1; 2.95 cm), (p <0.05) and the average values of the hip circumference (before: 58.3; 4.25 cm after: 56.2; 2.19 cm), (p <0.05). Conclusions. The substantiated technology of physique correction for female students taking into account geometry of their body mass in the course of physical training is aimed at achieving the corresponding purpose by using system, normative-target, personality-oriented approaches. The structure of the technology has included the purpose, tasks, principles, pedagogical conditions, stages, namely organizational-introductory, correctional-preventive, supportive.
