Lab testingFind what is holding you back
Measure the physiology behind your performance in one appointment, then get a training plan built from your real numbers.
VO2 max is one of the strongest predictors of how long you live.
In 2018, a study of 122,007 adults put a number on it.
The bottom 25% of cardiorespiratory fitness
were five times more likely to die
than the top 2.3%.
Being unfit carried more risk of dying
than smoking, diabetes or heart disease.
Your engine and body composition
Measured in a lab rather than guessed at by estimates.
VO2 max
The best single measure of aerobic fitness, and one of the strongest predictors of how long you'll live. Measured directly.
Limiting factor
Find the one system holding your fitness back, your heart, your lungs, or your muscles, so training targets the real bottleneck.
VO2 Max
#1 Health PredictorYour body's maximum capacity to produce energy. One of the strongest predictors of how independently you'll live decades from now.
Your Limiter
There are three components that make up VO2 max: Lung function to pull in oxygen, heart function to pump it to your muscles, and muscle function to extract the oxygen from your blood.
DEXA
See how much fat and muscle you carry, and where, down to the gram. Far past what a scale or BMI can tell you.
Body fat
See your body fat percentage, and how much is visceral fat surrounding your organs.
Your Fat
How much fat you carry, how it's distributed, and whether it's the kind that matters for metabolic health.

Where we test
Three clinics, in London and Manchester.
Professional Exercise Testing
We currently test in the UK, but we are collecting interest from other cities. We plan to partner with clinics in cities with growing interest.
Your plan starts with your numbers.
Archie builds it from what we measure, then keeps it current as you train.
