Episode 6~25 minHosts: Alex & Jo
Cardio, VO₂max & Fitness Age
Aerobic fitness, heart-rate zones, and what your VO₂max says about how long you’ll live.
Cardiorespiratory fitness is the single strongest statistical predictor of all-cause mortality — so Misi treats cardio with the same rigor as heavy lifting. Alex and Jo cover five-zone heart-rate modelling (Tanaka and Karvonen), polarized 80/20 training, and field-test VO₂max estimation.
They translate VO₂max into a biological Fitness Age and connect it to the Mandsager 2018 mortality data — framed positively as life-years to gain.
“Your cardio isn’t just a casual jog anymore; it is a precisely calculated longevity strategy.”
