The #1 exercise to prevent a heart attack is aerobic exercise (also known as cardio), according to cardiologists.
❤️ Why Aerobic Exercise Is the Top Pick
Aerobic exercise is considered the most effective form of physical activity for protecting your heart. It works by making you breathe harder and increasing your heart rate, which strengthens both your heart and lungs over time.
Cardiologist Dr. Luke Laffin from the Cleveland Clinic explicitly states that “aerobic exercise training should be promoted above all else”. The benefits are well-documented:
-
Reduces heart attack risk: Studies consistently show aerobic activity is superior to other exercise types for lowering heart attack risk.
-
Lowers blood pressure: It helps manage high blood pressure, a major heart attack risk factor.
-
Prevents coronary heart disease: Regular aerobic exercise reduces the risk of plaque buildup in your arteries.
🏃 Examples of Aerobic Exercise
You have plenty of options to choose from, including:
-
Walking or hiking
-
Jogging or running
-
Swimming
-
Cycling
-
Jumping rope
-
Tennis or pickleball
-
Soccer
For maximum heart benefits, cardiologists recommend at least 150 minutes of moderate-intensity aerobic activity per week. You can break this into shorter sessions throughout the week — even “exercise snacks” of a few minutes count. The key is to stay consistent and find activities you enjoy, so you can maintain the habit long-term.
🏋️ Don’t Skip Strength Training
While aerobic exercise is the top priority, it shouldn’t be your only form of activity. Health organizations like the American Heart Association also recommend strength training at least twice a week to work all major muscle groups. Combining both forms of exercise provides the most comprehensive protection for your heart.
