Unlock the secret of your body’s hardest-working organ

Conventional wisdom suggests that if you want something to last longer, you should go easy on it. And most of the time, that’s sage advice. But not when it comes to your body’s hardest-working organ: your heart.

Each day, your heart beats, on average, 100,000 times, pumping your blood through a vast system of blood vessels that’s more than 60,000 miles long.

But making your heart work even harder — through moderate- to high-intensity physical activity on a consistent basis — can help lower your blood pressure and make your heart stronger, says cardiologist Leslie Cho, MD.
