A 2018 Cleveland Clinic study followed 122,007 patients and found one metric predicted mortality better than almost any other: VO2 Max.
Not cholesterol. Not blood pressure. Not resting heart rate.
VO2 Max measures the maximum amount of oxygen your body can use during intense exercise. It reflects how efficiently your cardiovascular, respiratory, and muscular systems work together under stress.
The study found that patients who moved from the bottom 25% of fitness to above-average fitness reduced their mortality risk by roughly 50%. That is not a marginal improvement. That is a significant shift in health trajectory.
Peter Attia calls it "the most important metric for longevity." We agree.
Here is the problem: most people have never measured theirs. Wearable devices estimate it, but those estimates carry wide margins of error. A clinical breath analysis gives you a precise, objective number.
That number becomes your baseline. From there, you can make informed decisions about training, recovery, and long-term health planning.
VO2 Max breath analysis is available at our San Antonio, Austin, and New Braunfels locations. Our team walks you through your results and what they mean for your specific goals.
Start with the data. Build from there.
