Does VO₂max Training actually make a difference, or is it overhyped?

Cardiorespiratory fitness (VO2max) is one of the most extensively validated predictors of mortality in the scientific literature, supported by multiple large meta-analyses spanning tens of millions of observations and hundreds of cohort studies, including a scientific statement from the American Heart Association recommending it be tracked as a clinical vital sign. Weighing the data: VO₂max Training looks well-supported and consequential — the evidence is rated strong (90/100) and its estimated impact on longevity is also rated highly (95/100), making it one of the more solidly-backed choices on Vitaebase.
