Regular aerobic exercise often has the benefit (partly by promoting weight reduction) of reducing blood triglyceride levels and increasing the proportion of your total cholesterol that is made up of HDL cholesterol. Total and LDL choleste usually stay the same with exercise, but the ratio of LDL to HDL cholesterol is improved.
The appeal of dietary changes and increased activity is that although they can help improve lipid levels, they can also contribute lowering other cardiovascular risks such as obesity and high blood pressure. Changing your diet and exercise habits does not usually require an “all-or-nothing” approach. Anyone with the knowledge of what to do and the desire to do can make healthful changes that can rapidly become “second nature.”
