Frequently Asked Questions
What is VO2 Max and why is it considered the #1 longevity metric?
VO2 Max measures the maximum volume of oxygen (in milliliters) your body can transport and utilize per kilogram of bodyweight per minute (mL/kg/min). Groundbreaking epidemiological studies from the Cleveland Clinic show that elite cardiorespiratory fitness is associated with a 500% reduction in all-cause mortality risk compared to low fitness.
How does the George 1.5-mile running test estimate VO2 Max?
Developed for military and athletic benchmarking, the validated George formula estimates VO2 max: VO2 Max = 88.02 - (0.1656 × Bodyweight_kg) - (2.76 × Run_Time_minutes) + (3.716 × Gender_male1_female0).
What is considered a good VO2 Max by age and gender?
For men aged 30–39: 35–40 is Fair, 41–48 is Good, 49–54 is Excellent, 55+ is Superior. For women aged 30–39: 30–35 is Fair, 36–42 is Good, 43–48 is Excellent, 49+ is Superior. Elite cross-country skiers and cyclists often reach 75 to 90 mL/kg/min.
How can you increase your VO2 Max?
High-Intensity Interval Training (HIIT like the 4×4 Norwegian protocol: 4 intervals of 4 minutes at 90-95% max HR with 3 minutes active rest) combined with high-volume Zone 2 aerobic base training produces the fastest increases in VO2 max.
