Purpose: Body composition and some physical parameters of 12-week Cross-Fit training intensity in sedentary male individuals; Changes in body composition, heart rate, blood pressure, flexibility, endurance, and maximal strength were examined. Tool and Method: This study is in a private sports center operating in Çankırı, between the dates of 01 March - 31 May (12 weeks) in 2019, between the ages of 18- 54 years (average age is 40.73 ± 10.43 years, height is 177.93 ± 5.61 cm) 15 healthy adult men who did not do sports during the last 6 months participated and 12-week Cross-Fit training was done. The time set for training is 90 minutes. The participants were trained 4 days a week (Monday, Wednesday, Friday-Sunday) between 20:00 and 21:30. All the tests made to the participants were made between 08:30 and 12:00 in the morning, one day before and one day after the training programs. Statistical analysis of the findings obtained from the test results was determined by using the SPSS 25.0 for Windows package program. The subject group included in the study was analyzed at 0.05 significance level by using the reason for “Paired Samples T Test” to compare the results obtained after the measurements and to determine the significance levels of the differences between the averages (Samples were compared with the pre-post test). Results: In the light of the data obtained, it was observed that there was a statistically significant difference in the variables (body composition, cardiovascular measurements, physical measurements, maximal force measurements) in all values measured and measured (pretest-posttest). It is thought that; functional training, which is one of the determinants of these differences, is effective on the body composition of the sedentary men and some physical parameters, and the necessary training should be given to functional training activities in regularly planned and created training contents.
