How exercise affects your risk for high cholesterol and heart disease

All people, and especially those who have high cholesterol, should exercise at least 30 minutes on most if not all days. Exercise is a very effective way to reduce risk factors for coronary artery disease (CAD) and high cholesterol. Regular exercise:

• Raises "good" HDL cholesterol levels.
• May lower "bad" LDL cholesterol levels.
• Can help overweight people lose weight.
• Lowers blood pressure in some people.

There is growing evidence that regular physical activity protects against CAD. Added benefits of regular exercise include:

• Mental well-being and stress relief.
• Increased flexibility, if stretching is done afterwards.
• Increased bone strength, if the exercise includes weight-bearing exercises, such as jogging or lifting weights.

Customize your exercise program according to your fitness level, the health of your heart, and your personal preferences. Aerobic exercise (brisk walking, jogging, swimming, bicycling,) is best.

Some people, especially those who have a history of CAD, should discuss their exercise plans with their doctors before starting a vigorous fitness program.

Exercise is especially important for people who have high triglyceride levels, low HDL ("good") cholesterol levels, high blood sugar, and too much fat around the waist (metabolic syndrome). A large waist is more than 40in. for men and more than 35in. for women.
