Measure what actually matters.
Lab-grade cardiorespiratory testing for high-performing teams in Canary Wharf & the City. Twelve minutes on a treadmill. A number that predicts more than any annual health check.
Your annual check-up is missing the most important number.
Blood pressure and cholesterol describe risk. VO₂ max — the maximum oxygen your body can use — describes capacity. It's the single strongest predictor of long-term health we can measure, and it responds to training faster than almost anything else.
Higher all-cause mortality risk for the least fit versus the most fit — larger than smoking or diabetes.
Mandsager et al., JAMA Netw Open, 2018Capacity falls ~10% per decade from your thirties — unless you measure and train it.
Typical time to a measurable improvement with zone-based training built from your own test data.

Train, re-test, track
Follow your zones, then re-test to see progress in your dashboard. Most people improve within 12 weeks.
Optional · 3–6 months
One test. A report you'll actually use.
Zones are set from your measured ventilatory thresholds — not a 220-minus-age estimate. Exportable to Garmin, Apple Health and Strava.
Projected capacity to 75 if current training continues, versus the UK average trajectory.
Reviewed by our medical advisor. Anything flagged comes with a GP referral letter.
Aggregated and anonymised. Groups under 10 people are never shown. No individual result is shared with an employer.
“We'd run the same health check for a decade. Engela gave our people a number they wanted to improve — 60 of them ran London together the following April.”

The physiologist behind the mask.
Every test is run, and every report explained, by a qualified clinical exercise physiologist.
Oliver founded Engela Health and works one to one with people rebuilding strength, fitness and confidence — including people living with and beyond cancer and those recovering from cardiac events. He works alongside surgeons, oncologists and specialist nurse teams, and brings the same clinical rigour to every VO₂ test.

When fitness is part of recovery.
VO₂ testing is one side of what we do. Through Engela Health, our clinical exercise team runs supervised rehabilitation for people living with cancer or recovering from a cardiac event — at our Marylebone clinic, at home, or virtually.
Know your number. Then move it.

Questions, answered.

What actually happens during the test?
You wear a lightweight mask that measures every breath while running or cycling at gradually increasing intensity. Most tests last 8–14 minutes until you reach your maximum. Allow 45 minutes in total including warm-up and debrief.
Does my employer see my results?
No. Individual reports go to you only. Employers receive aggregated, anonymised data, and no group under 10 people is ever reported.
Can you test at our office?
Yes. Our mobile lab needs a room of about 4×4m with a standard power outlet. We handle setup, cleaning and scheduling.
Is it safe if I'm not very fit?
The protocol adapts to every level and starts at a walk. Everyone completes a health screening questionnaire first, and a resting ECG is included.
What equipment do you use?
Laboratory-grade metabolic carts, calibrated before every session, with a medical-grade treadmill or cycle ergometer.
How do we get started as a company?
Request a demo day. We'll test a pilot group of up to 12 people, then help you roll out to the wider team.
I have a heart condition or I'm having cancer treatment. Can I still test?
Possibly — but we'd start with a clinical assessment through Engela Health, our clinical exercise rehabilitation service in Marylebone. Send us an enquiry and we'll advise on the safest route.
