This Is The Best Exercise For Longevity, According To The Blue Zones Founder

Longevity has become nothing short of a buzzword recently, as more and more people strive for well-being into their later years. And by now, we know that several studies have linked regular exercise—even in the form of small daily movements—to a longer life.

According to New York Times bestselling author and expert in Blue Zones (places in the world with the longest-lived people) Dan Buettner, the very best exercise you can do to support longevity is none other than walking. (No kidding!)

As Buettner tells mbg, taking a brisk walk can offer you roughly 90% of the physical activity benefits of training for a marathon—at a fraction of the exertion and impact. And not only that, but you can take a daily walk for your entire life, he notes, adding that walking "engages well over 100 muscles and also improves cognitive functioning1."

Buettner has found that regular movement is embedded into the culture and lifestyle of Blue Zones, which likely plays a role in the number of centenarians in these places.

"The big epiphany of Blue Zones is they're moving every 20 minutes, but not because there's some regimen. Their environment is set up in such a way that they're nudged into movement," he previously explained on an episode of the mbg podcast.

Research supports the idea that doing micro-movements all throughout the day can build more longevity-supporting muscle mass than just hitting one tough gym session. Taking just a 10-minute stroll every day has been linked in research to increased longevity in people 85 and older.2

If you've never heard of earthing, it simply entails walking barefoot on the earth. That might sound hippie-dippie, but one study actually found earthing changes the electrical activity in the brain4, as measured by electroencephalograms, so the benefits go beyond just grounding to the earth.

Not going the earthing route? You'll want to make sure you're supporting your daily walk with a good pair of supportive walking shoes.

In addition to that, Jonathan FitzGordan, a yoga teacher and creator of Core Walking, previously wrote for mbg that most people should focus on shortening their stride, leaning slightly forward, and alternating their arms and legs as they walk.
