It is always important to talk with your doctor before starting an exercise program, particularly if you have certain health conditions.

To improve your heart and lung fitness, aim for 30 to 60 minutes of aerobic exercise three to four times a week.

Working out when you have a serious illness or health problem can be challenging. But for most people who have health issues, exercising can improve their prognosis and well-being. In fact, exercise can play an important role in helping you cope with or recover from a health challenge or accident.

The key to cardiovascular fitness is getting a good but safe aerobic workout. Heart rate monitors, which monitor your heart rate while you exercise, can help you do that with ease.

Lack of physical activity has clearly been shown to be a risk factor for cardiovascular disease.

Unlike other muscles, your heart muscle does not tire from use. Your heart is like other muscles, however, in that it needs exercise to work efficiently. What kind of exercise would that be? All it takes is a brisk 30-minute walk most days of the week.

If you think that you can’t begin a strength-training program because you have heart disease, think again.
