Among the physical fitness workouts; whereas the weight training is one of the most prevalent physical activities used for men, the zumba dance workouts has become popular for women in the last decade, as an entertaining alternative approach. In this research, the effects of the weight training on the body composition in men and the zumba dance workouts in women have been studied. 90 sedentary individuals (44 men, average age: 30.70 +/- 6.44; 46 women, average age: 29.13 +/- 5.80) attending a fitness center had received weight training and zumba classes (during 2 months, 3 days each week, each session 45/60 minutes). The exercise intensity that had been kept low at the beginning was increased in the following weeks for both programs. The body composition analysis have been carried out at the start and then monthly, through bioelectrical impedence method. During the process; the medical histories of the participants as well as their levels of readiness for and participation to the physical activities have been monitored. Both sex have been evaluated separately. The descriptive statistics techniques and repeated measures ANOVA have been used to analyze the data. At the end of the study, the positive effects of both exercise programs on the body compositions of the sedentary men and women have been observed. As a conclusion, it has been recorded with the present study once again that the weight training is still an efficient and valid method for men and also, the zumba workouts are efficient for women as a popular method.
