What this source says

Review connecting cardiorespiratory fitness and longevity-oriented outcomes.

Why it matters

This source is part of LHN's general longevity evidence trail. Reading the original helps separate what the source actually addresses from broader online claims.

What it does not prove

Exercise evidence is stronger than many biohacking claims, but individual plans still need context.

How LHN is using it

This brief records the source in the public evidence trail and links to the original. It does not turn a paper, registry entry or regulatory document into personal medical advice. The source's design, population and stated limitations still determine what conclusions are reasonable.
