Exercise training and physical activity modified body fat percents and serum lipid profiles, but the influences of different types of exercises and combination of them on body fat percents and serum lipid profiles has rarely been investigated. The aim of this study was to investigate the effects of 12 weeks combination training included aerobic dance, step exercise and resistance training on body fat percents and serum lipid profiles in sedentary females. Eighty subjects randomly selected from 100 volunteered healthy sedentary females (25-45 years) based on American College of Sports Medicine and Physical Activity Rating Questionnaire in AL-ZAHRA University (Tehran, Iran). This subjects randomly divided in two groups such as, Exercise (n= 40) and Control groups (n= 40). Subjects in exercise group were training for 12 weeks, 3 sessions in week, and 60 minute in sessions with 60-80 percent of Heart Rates Reserve (HRR). Combination training program include aerobic dance, aerobic step exercise and resistance training was performed based on progressive overload training principal. Total Cholesterol (TC), Triglyceride (TG), Low Density Lipoprotein Cholesterol (LDL_C), High Density Lipoprotein Cholesterol (HDL_C) and Body Fat percents (% BF) has been measured before and after 12 weeks training program. Data compared with two tailed paired and independent sample t test (p≤0.05). The results showed that levels of HDL_C and % BF significantly modified after 12 weeks training (p< 0.05). There were no significant changes in TC, TG and LDL_C. These results indicated that moderate intensity combined training included aerobic dance, step exercises and resistance training have positive effect on some serum lipid profiles and body fat percents in sedentary females
