Being physically active can help lower your cholesterol level, whether it involves everyday activities like cleaning or gardening or a structured exercise program. Exercise helps lower cholesterol levels several ways:

• Exercise increases the amount of HDL cholesterol (the good kind of cholesterol) in your blood, while reducing the amount of LDL cholesterol (the bad, artery-clogging kind of cholesterol).
• Exercise promotes weight loss and weight control.
• When you exercise, you tone up your whole body's circulation, helping to clear away clots in the blood vessels and making the heart a stronger, more efficient pump.

Types Of Exercise
You don't have to run marathons to benefit from exercise - even modest increases in your level of physical activity can help lower your cholesterol levels.
Vigorous activities like walking, jogging, biking, and swimming are called aerobic activities, and they are especially good at conditioning the heart and improving circulation. If you choose one of these activities, be sure to start slowly and build up gradually to avoid strain and injury.
Exercises are generally grouped into three types depending on the overall effect they have on the human body:

Flexibility exercises, such as stretching, improve the range of motion of muscles and joints. Aerobic exercises, such as cycling, swimming, walking, rowing, running, hiking or playing tennis, focus on increasing cardiovascular endurance. Anaerobic exercises, such as weight training, functional training or sprinting, increase short-term muscle strength.
