If you want to lower your blood cholesterol levels, eating a low-fat, low-cholesterol diet is an important step. But to get even better results, you should throw some exercise into the mix.

Studies show that people who exercise regularly in addition to eating healthfully fare better than those who focus solely on diet. Exercisers have higher levels of the "good" cholesterol (HDL, or high-density lipoproteins) and lower levels of the "bad" cholesterol (LDL, or low-density lipoproteins).
