What It Is
Know your engine.
VO₂ max measures how efficiently your body takes in, moves, and uses oxygen during exercise — the gold standard for measuring cardiovascular fitness, endurance, and metabolic efficiency.
It answers one of the most important questions about your health: how well your engine runs. Your test also reveals your true heart rate zones, so every session can be built around how your body actually performs.

Benefits
Why test your VO₂ max
The data takes the guesswork out of progress.
-
Trade guesswork for real data
Know your actual aerobic capacity — not an estimate from an app or a formula.
-
Find your real heart rate zones
The “220 minus your age” formula can miss your true numbers by 20 beats per minute or more. A lab test measures you directly.
-
Track a vital sign that matters
Low cardiorespiratory fitness is one of the strongest predictors of future health risk — and one you can train.
-
Train smarter, not just harder
Easy days that are truly easy and hard days that are truly hard, so every session moves you forward.
-
Not just for athletes
For anyone who wants to train smarter, support long-term health, or stay active as they age.
-
Measure real progress
Retest to see whether your training, nutrition, and recovery are actually working.

Frequently asked questions
What is VO₂ max?
VO₂ max measures how efficiently your body takes in, moves, and uses oxygen during exercise. It’s the gold standard for measuring cardiovascular fitness, endurance, and metabolic efficiency.
What happens during a VO₂ max test?
You’ll walk or run on a treadmill (or ride a bike) wearing a mask that measures your oxygen use as you breathe. The exercise itself takes 10–15 minutes; plan for about an hour total.
How should I prepare for my test?
Wear athletic clothing and avoid heavy meals and caffeine for 2 hours before your appointment.
Who should get tested?
Anyone who wants to train smarter, support long-term health, or stay active as they age — not just athletes.
How is a lab test different from my smartwatch?
A lot more accurate. Studies comparing smartwatch estimates to lab results found they’re off by 13–16% on average — sometimes far more. If your training decisions depend on the number, get it from a lab.
How often should I retest?
Every 12 weeks if you’re following a specific training plan, or every 6–12 months for general tracking.
How much does VO₂ max testing cost?
VO₂ max testing is $99, or $79 for members. Every membership pathway includes it two to four times per year.
