There isn’t a scientifically established single “#1 exercise” that guarantees prevention of a heart attack. The strongest evidence supports regular aerobic activity combined with muscle-strengthening exercise.
❤️ A simple heart-friendly choice: brisk walking
For many adults, brisk walking is an excellent starting point because it’s accessible and can improve cardiovascular fitness, blood pressure, blood sugar, and cholesterol.
A practical goal is:
- 150 minutes per week of moderate-intensity aerobic activity, such as brisk walking—roughly 30 minutes on 5 days.
- Add muscle-strengthening exercises at least 2 days per week.
- If you’re currently inactive, start with shorter sessions and gradually increase.
You don’t need to exercise continuously for 30 minutes; shorter bouts of activity can also contribute to your weekly total.
Don’t ignore symptoms
Stop exercising and seek medical attention if you develop chest pressure/pain, severe shortness of breath, fainting, or unexplained severe dizziness.
And exercise is only one part of prevention. Not smoking, controlling blood pressure and cholesterol, managing diabetes, maintaining a healthy weight, eating a heart-healthy diet, and taking prescribed medications can be just as important.
If you’re over 60 or haven’t exercised regularly, I can give you a safe 20-minute beginner walking routine designed specifically for cardiovascular health.
