VO₂ Max: The #1 Predictor of Longevity

Dr. Peter Attia called it the single most powerful marker for how long you'll live. More predictive than smoking, blood pressure, or any other risk factor.

"People that maintain high VO₂ Max for their age live longer, and more importantly, they live better.

Why VO₂ Max Is the Gold Standard for Longevity

VO₂ Max measures your body's ability to use oxygen during exercise — the most accurate indicator of cardiorespiratory fitness and overall health. Unlike other health markers, VO₂ Max directly predicts your healthspan.

🎯 Most Predictive Marker

Research on 122,000 people found VO₂ Max to be the strongest predictor of mortality — stronger than smoking, blood pressure, or cholesterol.

🧬 Reveals Biological Age

Your VO₂ Max shows your true biological age versus chronological age. A high VO₂ Max means your body functions younger than your years.

💪 Trainable & Improvable

Unlike genetics, VO₂ Max can be improved through targeted training. But first, you need to measure it to establish your baseline.

📊 Personalized Training Zones

Your test results include customized heart rate zones for maximum efficiency — so you train smarter, not just harder.

⏱️ Track Progress Over Time

Regular testing (every 3-6 months) shows exactly how your training is working and where to adjust for continued improvement.

🏥 Medical-Grade Accuracy

Unlike fitness trackers or estimates, our VO₂ Max test provides lab-quality data you can trust for serious health decisions.

"At a population level, both men and women are basically falling off a cliff, on average, around age 75."

Frequently Asked Questions

What exactly is VO₂ Max?
VO₂ Max (maximal oxygen uptake) is the maximum amount of oxygen your body can use during intense exercise. It's measured in milliliters of oxygen per kilogram of body weight per minute (ml/kg/min). The higher your VO₂ Max, the more efficiently your cardiovascular system delivers oxygen to your muscles — and the better your overall health and longevity prospects.
How long does the test take?
The actual test takes 15-20 minutes. You'll spend about 45 minutes total at our facility, including preparation, the test itself, and a brief cool-down. We also include a free consultation to review your results and answer questions.
Is the test safe? What if I'm not very fit?
Yes, the test is very safe. Our trained staff monitors you throughout, and you can stop at any time. The test is designed to gradually increase intensity, so it works for all fitness levels. We've tested everyone from elite athletes to people just beginning their fitness journey.
What will I learn from my results?
You'll receive a comprehensive report including: your VO₂ Max score, percentile ranking for your age and gender, personalized heart rate training zones, comparison to elite athletes and general population, and specific recommendations for improvement. We'll explain everything in your free consultation.
How often should I retest?
We recommend retesting every 3-6 months to track progress and adjust your training plan. This timeframe allows enough time to see meaningful improvements while keeping you accountable to your longevity goals.
Can I improve my VO₂ Max?
Absolutely! Unlike genetics, VO₂ Max is highly trainable. With the right training program (which we'll help you design based on your results), most people can improve their VO₂ Max by 15-25% within 3-6 months. The key is knowing your baseline and training in the right zones.
Do I need a referral?
No referral is needed. Simply book your appointment online and come in at your scheduled time. We provide direct access to this essential longevity test.
Can I use HSA/FSA funds?
Many clients successfully use HSA/FSA funds for VO₂ Max testing. We provide detailed receipts that you can submit to your HSA/FSA administrator. Check with your specific plan for coverage details.
What should I wear and how should I prepare?
Wear comfortable athletic clothing and shoes suitable for running or cycling. Avoid eating a large meal 2-3 hours before your test. Stay hydrated, but don't overdrink right before. Avoid intense exercise for 24 hours prior. We'll provide all testing equipment.
