Exercise Linked to Younger Biological Age, But Effect Is Modest

Pulling together 44 studies on nearly 145,000 people, researchers found that more physical activity is tied to a younger biological age, but only on certain epigenetic clocks. The effect showed up clearly on GrimAge and Horvath clocks, but not on Hannum or PhenoAge. The size of the benefit was small, and most data came from snapshot studies, so we can't say exercise actually causes the slowdown yet.
