When you exercise blood moves, the body sweats, your heart beats faster, and in general you are moving through blood transportation, LDL, HDL, and triglycerides to be rid out of the body. Do this enough and you have a cycle of keeping HDL fat UP which cleans out the arteries etc. Exercise is one way of getting high HDLs...

1. Exercise increases blood flow to your heart. This strengthens your heart and helps it pump more blood with less effort. Therefore it beats fewer times a minute and doesn't work as hard. 2. Exercise helps control your weight. Correct weight = less risk for high blood pressure, high cholesterol, and diabetes. 3. Exercise reduces stress. Stress = cortisol production = weight gain and inflammation. Inflammation = hardening of blood vessel walls = strokes, heart attacks, aneurysms. 4. Exercise helps keep cholesterol low. Cholesterol = plaque buildup in arteries. This equals heart attacks and strokes. 5. Exercise keeps blood vessel walls flexible. This prevents "hardening of the arteries", which can = heart attacks and strokes.
