Your Aerobic Capacity, Measured Precisely
VO2 Max is the gold standard measurement of cardiovascular fitness, and measures the maximum amount of oxygen your body can use during intense exercise. It determines your aerobic ceiling, defines your training zones, and gives you a precise picture of how your heart and lungs are actually performing.
Most people guess at this data. They use age-based formulas, train in zones that are probably wrong, and wonder why their fitness is not progressing the way it should. A clinical VO2 Max test replaces all of that with actual measurements of your physiology. At Priority Fitness, we use the Korr Medical Technologies system, which is the same equipment used in clinical research and hospital settings, to produce data you can trust and build from.
The Korr Medical Standard
Not all VO2 Max tests are created equal. The Korr system uses direct gas exchange analysis and measures what you actually breathe in and out during the test, rather than estimating your capacity from proxy measurements. This is the same methodology used in academic research and clinical medicine. What you get is not an approximation. It is your number.
YOUR PRECISE TRAINING ZONES
Generic training zones are built from averages. Your zones are built from your physiology. A VO2 Max test gives you the exact heart rate ranges where your body burns fat efficiently, builds aerobic capacity, and works at maximum intensity, so that every training session is targeted rather than guessed at. For athletes, this is the foundation of intelligent periodization.
A PICTURE OF YOUR CARDIOVASCULAR HEALTH
VO2 Max is not only for competitive athletes. It is one of the most reliable indicators of long-term cardiovascular health and longevity. Understanding where your aerobic capacity sits (and how it changes over time) gives you a meaningful window into how your heart and lungs are aging and what you can do about it.
WHAT HAPPENS AFTER THE TEST
-
You receive your VO2 Max number and personalized heart rate training zones
-
Ben walks you through your results in plain language before you leave
-
You leave with a clear picture of what your data means and exactly what to do with it
