VO2 max measures how well your body takes in and uses oxygen, and researchers consider it one of the strongest predictors of long-term health (Mandsager et al., 2018).
In a Cleveland Clinic study of 122,007 adults, those with the lowest cardiorespiratory fitness had a mortality risk comparable to or greater than smoking, diabetes or coronary artery disease. In that study, higher fitness was linked to lower risk at every level, with no upper limit observed (Mandsager et al., JAMA Network Open, 2018).
How we train it
