The aim of the present study was to investigate the effect of 12 weeks of progressive strength training on lipid profile levels in inactive middle-age men. Subjects of the study were 12 men (age 40-60) who participated is the study voluntarily. The training program began two days a week in the first month and continued to three non-consecutive days a week. The training intensity began with 60 percent 1rpm during the first two weeks and increased to 75-80 percent 1rpm.Triglyceride, cholesterol, LDL and HDL were measured before and after 12 week. Data was analyzed using paired t-test statistical methods. Research findings showed that levels of triglyceride, total cholesterol, LDL and HDL no significant differences in post-test compared to pre-test (p=0.062, p=0.180, p=0.082 and p=0.476 respectively). The results of this study showed that strength training cannot change the blood lipid and lipoprotein levels in inactive middle-aged men. In fact, subjects with normal lipid profiles may require greater exercise stimulus and energy expenditure further improve lipid profiles.
