Consistent, long term, aerobic cardio exercise (running, elliptical, cycling, swimming, etc) increases VO2 Max, which is the one number that most closely correlates with longevity.

The easiest way to have this measured is the wear a Garmin watch.

For example, I started running in July 2022 (66 y/o) with a VO2 Max of 35 (about average for a 66 y/o).

This week (3 years later) my VO2 Max is 49 (top 5% for a 69 y/o).

There are many good places to get info about VO2 Max.

A great place to start is with this short video by Dr. Peter Attia…author of “Outlive”…
