Is There a “Number One” Exercise to Prevent a Heart Attack?
There isn’t a single exercise that cardiologists consider a guaranteed number-one heart-attack prevention exercise. The strongest general recommendation is regular aerobic activity, and brisk walking is one of the simplest ways to achieve it.
The American Heart Association recommends that adults aim for at least 150 minutes of moderate-intensity aerobic activity per week—for example, brisk walking—or 75 minutes of vigorous activity. It also recommends strength training at least twice a week.
Why brisk walking?
Brisk walking gets your heart beating faster without requiring specialized equipment. Regular physical activity can help lower blood pressure and improve cholesterol, blood sugar, fitness, and weight—all factors associated with cardiovascular risk.
A practical starting point is 10–15 minutes of walking, gradually building toward about 30 minutes on most days. Even amounts below the recommended target can provide benefits.
Important: If you have known heart disease, significant chest pain, unexplained shortness of breath, or you’ve been inactive for a long time, ask a healthcare professional how to begin safely rather than suddenly starting strenuous exercise
