This study is looking at one specific mechanism by which exercise may be helpful in improving some aspect of your health. It's not especially useful to look at just this study though, as it doesn't actually link to any outcomes (the telomere protective expression may or may not actually reduce your risk for cardiovascular disease). It's more useful to look at studies that have looked at actual outcomes (e.g. reducing the incidence of heart attack or stroke, etc). In those cases, the bulk of the evidence points to 30 minutes a day, 5 days a week of moderate exercise (e.g. a brisk walk or jog) being the best 'bang for your buck'.
