Physical inactivity, high blood pressure, and smoking are risk factors for heart disease. These risk factors can be reduced by living a healthy lifestyle, including exercise.
Look at all the ways exercise can help your heart:
Reduces your risk of developing heart disease and can help prevent existing heart disease from getting worse
Lowers your risk of developing high blood pressure
Lowers blood pressure in some people who have high blood pressure
Raises your high-density lipoprotein (HDL), or "good," cholesterol
Lowers your low-density lipoprotein (LDL), or "bad," cholesterol
Lowers the amount of triglycerides, a form of fat, in your bloodstream
Helps you lose extra weight, which can strain your heart
Makes your heart and lungs work more efficiently
Over time, fat and cholesterol can build up in your blood vessels. When arteries that supply the heart and brain with blood become clogged, a heart attack or stroke can occur. Exercise can help keep the blood vessels open. This can help prevent heart disease or stroke.
Exercise may also protect against stroke. Walking, stair-climbing, dancing, jogging, and other activities of at least moderate intensity also reduce stroke risk. Plus, exercise can help you prevent or manage several chronic diseases that become more common with age: type 2 diabetes, osteoporosis, and arthritis.
Both your body and mind can benefit from exercise. Exercise can help you manage stress. It's not clear whether stress affects the heart directly or has an effect on other risk factors and behaviors that affect the heart. These may include blood pressure, cholesterol levels, smoking, and overeating. Cutting down on stress, however, can at least make your life more enjoyable. Exercise can also boost your self-image and help counter anxiety and depression.
You don't have to strain your body to benefit from exercise. Even moderate exercise is good for you. The CDC and the American Heart Association recommend at least 30 minutes of moderate intensity aerobic activity, 4 to 5 days a week. They also recommend moderate to high intensity muscle strengthening activity at least 2 days a week. Examples of moderate activities include:
For increased benefit to your heart and lungs, try more vigorous aerobic activity. These are examples of more vigorous activities:
Jogging or running
If you already have high blood pressure and high cholesterol, you should target a longer workout to control these risk factors. Target 40 minutes of moderate to high intensity aerobic exercise to lower both cholesterol and blood pressure.
Use these tips to move toward a more active life:
Choose activities you like. The key to starting and sticking with an exercise program is to pick activities that you enjoy. Then choose a convenient time and place to work out. Try to make exercise a habit. Do different activities rather than relying on just one so that you don't become bored with your routine. Finding an exercise partner may make it easier to stick to a regular schedule. If you miss an exercise session, don't worry. Just find another way to be active that day.
Build up your endurance. Start out by exercising slowly, especially if you haven't been active for a while. This will allow your muscles to warm up. Gradually build up how hard, how long, and how often you exercise. Be careful though. Overdoing exercise increases the risk of injury. Listen to your body, and don't ignore any pain in your joints, ankles, feet, or legs. If you stretch before exercising, do so gently. Also take plenty of time to stretch at the end of each session. This can help you become more flexible.
Drink plenty of water. While you exercise, drink some water every 15 minutes, especially in hot, humid conditions. Be sure to drink before you feel thirsty. You can't always rely on thirst alone to tell you when you need more fluids.
Check with your healthcare provider before starting any new exercise program. This is especially important if you have been inactive for a while. It is also important if you have a chronic health problem like heart disease, diabetes, or obesity, or if you are at high risk for developing these problems. If you have any chest pain or discomfort during exercise that goes away after you rest, call your healthcare provider right away. If your exercise-induced chest pain does not go away with rest, call 911. This can be a sign of heart disease and a heart attack.
Make exercise a part of your life with these tips:
Walk, jog, or bike around town instead of driving.
Take an activity break during the day instead of eating a snack.
Find out if your local shopping mall opens early for indoor walkers.
Listen to music or watch TV to keep yourself entertained while you exercise.
Surround yourself with people who support and encourage you.
Set realistic exercise goals. Reward yourself when you achieve your goals.
Plan vacations around activities like hiking or swimming.
Park your car in the back of the parking lot to have a longer walk into the store when you go shopping.
