The cardiologist’s verdict is clear: aerobic exercise is the single most impactful type of physical activity for reducing heart attack risk. It directly strengthens the heart, lowers blood pressure, improves cholesterol, and reduces the risk of coronary heart disease—the leading cause of heart attacks.
While strength training offers valuable additional benefits, cardio should be the foundation of any heart-healthy exercise routine. And the best part? You don’t need a gym membership or expensive equipment. A brisk walk, a swim, a bike ride, or a dance session can all do the job—as long as you do it regularly.
As Dr. Laffin puts it, “Aerobic exercise training should be promoted above all else” for heart attack prevention . Most people never consider it—but maybe they should.
