Visit your doctor for a physical exam, as she can determine whether you have a heart condition and could benefit from an exercise stress test. She will measure your heart rate and blood pressure to evaluate the strength of blood flow through your body, and she may also test your blood cholesterol level.

Next, you'll exercise on a treadmill or stationary bicycle wearing a blood pressure cuff. The test requires that you gradually increase the strenuousness of the workout until you reach a target heart rate, all while a doctor or technician monitors your EKG and heart rate and watches for any symptoms. She will also periodically test your blood pressure. It is important to confide in the doctor about any symptoms or discomfort that you feel so she can diagnose you correctly.
