Just 30 minutes a day of these type of exercises could help you beat heart disease

Heart disease remains one of the world’s biggest killers, claiming millions of lives each year. But according to experts, there’s one type of physical activity that stands above the rest when it comes to strengthening your heart and lowering your risk of a heart attack — and you probably already know how to do it.

Speaking to TODAY.com, Dr. Luke Laffin, a preventive cardiologist and co-director of the Center for Blood Pressure Disorders at the Cleveland Clinic, didn’t mince words: “Aerobic exercise training should be promoted above all else.”

Why 'Cardio' Really Lives Up to Its Name

Aerobic exercises — think walking, jogging, swimming, cycling, or even dancing — work by raising your heart rate and encouraging your body to use oxygen efficiently for energy. They involve large muscle groups, which in turn train your cardiovascular and respiratory systems to perform better.


Over time, the Cleveland Clinic notes, this kind of movement helps the heart beat more efficiently, strengthens blood vessels, improves oxygen circulation, lowers blood pressure, boosts “good” cholesterol, and slashes the risk of heart attack and stroke.

It is no accident that “cardio” takes its name from the Greek word for heart. As Dr. Kerry Stewart, an exercise physiologist at Johns Hopkins, explains, aerobic activity paired with resistance training forms the cornerstone of heart health. While strength training and high-intensity intervals also benefit the heart and lungs, cardio delivers the most direct impact in lowering heart attack risk.

The Magic Number for a Healthy Heart

Federal health authorities recommend that adults aim for at least 150 minutes of moderate-intensity aerobic activity per week. That could mean just 30 minutes a day for five days, with two days of rest in between. Dr. Laffin adds that doing more than the minimum only increases the health benefits.

The Baylor College of Medicine suggests splitting the time into manageable sessions, while Dr. Ben Levin, a cardiologist at UT Southwestern Medical Center, encourages choosing activities you enjoy: “Jog, swim, golf, hike, play basketball, dance, do yoga — whatever you love to do. The most important thing is to get out there and do it.”

From brisk morning walks to weekend bike rides, aerobic exercise is not about perfection — it is about consistency. Experts agree that moving your body in a way that elevates your heart rate for sustained periods can be one of the most powerful, low-cost ways to protect yourself from the world’s leading cause of death.
