As a general rule, it's better for people with heart failure to stay active. That might sound like contradictory advice, since the heart is already having trouble keeping up with the body's demands. Why make it work even harder?

Moderate exercise can help the heart get stronger. Most people find that exercise improves their symptoms, reduces stress and boosts energy levels. Regular exercise also may lead to other important health advantages, including weight loss, better circulation and blood pressure, and lower cholesterol levels — all of which are especially important if you have heart failure.

The healthcare team will work with you to develop an appropriate exercise plan. Often they'll start by giving you a stress test to measure your heart function during exercise (either walking on a treadmill or riding an exercise bike). This helps the physician know how much activity your heart can handle.
