Why small fitness steps could lead to a longer life, according to Dr. Jeremy London

Board-certified cardiothoracic surgeon Dr. Jeremy London, based in Savannah, Georgia, explains why VO2 max and muscle mass are the main indicators of longevity.

There are numerous paths to living a longer, healthier life, mostly through physical activity, diet and other lifestyle factors.

But according to board-certified cardiovascular surgeon Dr. Jeremy London, the key to longevity could come down to two main metrics.

In a video posted to his more than 1 million followers on social media, London broke down how two factors – VO2 max and muscle mass – can help increase health span and lifespan.

WHAT PEOPLE WHO LIVE TO 100 YEARS OLD HAVE IN COMMON, ACCORDING TO SCIENCE

VO2 max is an indicator of how efficiently the body utilizes oxygen with intense exercise, said London, who is based in Savannah, Georgia.

"In other words, the health of your cardiovascular system," he said. "Not surprising that it increases health span and lifespan."

In an on-camera interview with Fox News Digital, London added that VO2 max is "statistically" the No. 1 indicator of longevity. (See the video at the top of this article.)

In comparing individuals with a low VO2 max to those with a higher VO2 max, scientists have identified "magnitudes of improvement" in reducing cardiovascular morbidity and mortality, as well as increasing longevity.

"Even if you’ve never exercised, or if you haven’t exercised for a long time, you can still get benefits."
