Exercise and Heart Health
Staying physically fit has seemingly endless benefits. In addition to helping prevent heart disease, exercise is known to reduce stress and improve sleep, energy level, mood and even brain functioning. For people with heart disease, exercise can keep symptoms in check and prevent problems from getting worse.
Most Americans don’t get enough exercise and, therefore, don’t reap the health benefits. Find out how you can stay active at any age—even if you have heart disease.
Exercise and Your Heart
Regular exercise reduces the risk of many forms of heart disease, including heart attack
, peripheral artery disease
and coronary heart disease
Lowers blood pressure
Lowers LDL (bad”) cholesterol that can clog your heart’s arteries
Boosts HDL (“good”) cholesterol
Opens blood vessels and gets your heart pumping, which improves circulation
Helps you shed excess pounds, reducing the strain on your heart
Helps your body maintain the right balance of hormones and other factors involved in clotting and inflammation that may promote fatty buildups in the heart’s arteries
Americans fall short on exercise. Together, we can do better.

Only half of U.S. adults get the recommended amount of exercise, and that proportion drops among older age groups. Stay healthy no matter what your age by getting at least 30 minutes of moderate-intensity activity at least five days a week.
Most people can safely exercise without any special medical evaluation. Just get out and go!
In addition to the benefits for your heart health, exercise:
What’s the Right Amount of Exercise?
Improves mood and reduces depression by boosting “feel-good” hormones called endorphins
Improves sex drive
Keeps stress levels in check
Builds lean muscle mass, which helps you burn calories even when you’re not exercising
Improves balance and prevents falls, especially among older people
Lowers blood sugar levels, which helps reduce the risk of type 2 diabetes
Helps prevent osteoporosis and arthritis
Helps prevent some types of cancer, and may improve the body’s response to cancer treatments
May ward off dementia, or at least delay its onset
Can help you build a healthier lifestyle overall—research shows that people who exercise regularly are less likely to smoke and tend to choose healthier food options
Your body needs at least 2 1/2 hours of moderate-intensity activity plus two sessions of muscle strength training per week, according to the Physical Activity Guidelines for Americans
. For example, you could take a brisk 30-minute walk at least five times a week and do two sessions of weight lifting or Pilates.
What’s moderate intensity? Use the talking—or breath—test: If you can easily carry on a conversation with full sentences, you’re not exerting enough effort. Try increasing the intensity of your activity. If you’re walking, quicken your pace. If you’re doing a cardio workout, add some jumps. For strengthening, push yourself by adding more weight or more repetitions.

Alternatively, you can aim for 75 minutes of high-intensity activity per week, plus two sessions of muscle strength training. Examples are running, high impact aerobics and high intensity interval training, called HIIT. When doing high-intensity exercise, you should be breathing hard such that you can only say a few words at a time.
If you’re new to exercise, it’s OK to start slow. Begin with shorter—but regular—sessions and work your way up. Remember, any amount of physical activity is better than none at all. If you have heart disease or another heart condition
, check with your health care team before starting or intensifying your activities.
