What are the potential benefits of exercise on cardiovascular risk reduction, hypertension, and insulin resistance?

Exercise increases the activity of lipoprotein lipase, which favors the lipolysis of triglycerides rich in lipoproteins as an initial step in raising HDL cholesterol levels.
Exercise has an independent effect on reducing blood pressure, with a decrease of 8-10 mmHg in both systolic and diastolic blood pressure.
Exercise improves insulin sensitivity, resulting in a modality of treatment for insulin resistance.
Exercise has no effect on the renin-angiotensin system.
