Why VO2 max, strength, and muscle mass are powerful health markers

Nick draws the parallel to a point Peter frequently makes about VO2 max: you can't cram for it the week before a test. Peter confirms the analogy extends to all three fitness metrics — VO2 max, muscle mass, and strength are what he calls integrators. They aggregate and reflect the cumulative effect of years of consistent training, making them uniquely reliable as health signals. This also means they are uniquely difficult to improve on a short timeline. Peter tells patients who show up in the bottom 5% of all three metrics that this is not a one-year project — it may take three years just to move VO2 max from 30 to 50. Understanding this time horizon is critical, he argues, both for setting realistic expectations and for grasping why starting early (or not stopping) is so important.
VO2 max, muscle mass, and strength are powerful predictors precisely because they cannot be faked. They are living records of years of accumulated work — turning around a VO2 max from 30 to 50 takes roughly three years of dedicated effort.
