Methodology
VO2 Max and Lifespan, How to Train It
Francesco Zen, founder of ZTraining · Last updated June 20, 2026
Why VO2 max isn't treated as a training metric alone
Most approaches treat VO2 max purely as a cardiovascular number to chase through training volume. The approach here treats it as one part of a wider healthspan system, physical work, nutritional support for blood quality, and breathing pattern work all contribute together, not separately.
Why the exact protocol stays proprietary
This is genuinely part of the proprietary methodology behind ZLIFE's longevity work, refined specifically for time-constrained clients rather than published as a generic training plan. The principle is transparent, the precise application is not.
