Heart rhythm
6-lead electrocardiogram
Records your heart’s electrical activity from six perspectives — a fuller read on rhythm, rate and cardiac stress than a single-lead device.

Discover Your EnduroAge™
Your body has a real biological age — and you can change it. A complete longevity & performance assessment that turns 60+ health markers and your VO₂ max into one clear score, and the exact steps to move it.
Clinical-grade testing
Professional VO₂ max plus a 60+ marker Longevity Scan, all in one visit.
90 minutes on-site
At The Outpost, Saltburn-by-the-Sea — guided by our team from start to finish.
One score, one plan
Everything interpreted into a single EnduroAge score and a clear 30-day plan.
Coaching, not diagnosis
A performance & longevity assessment in plain language — never clinical jargon.
What EnduroAge is
One number that captures how well you’re really ageing.
We combine a clinical-grade Longevity Scan with a professional VO₂ max test, then interpret everything across five pillars into a single EnduroAge score out of 100 — your biological age, made visible. It’s a baseline you can act on, and re-measure as you improve.
The era of reactive health is over
The earlier you know, the better.
Most of what shapes how you age happens quietly — years before you’d ever feel it. EnduroAge is built to surface those signals early, while there’s still time to act on them.
Metabolic health
9–12 yrs
That’s how long type 2 diabetes can quietly develop before it’s diagnosed. Catching the early signals is when they’re easiest to change.

Cardiac health
−60%
Reduction in severe cardiovascular risk when high blood pressure is caught and managed before the first symptom ever appears.

Fitness & longevity
5×
Low cardiorespiratory fitness carries a greater long-term mortality risk than smoking, diabetes or high blood pressure — and it can be trained.

Figures from independent research, shown for context — EnduroAge gives you early-insight signals, not a medical diagnosis.
What we measure
The five pillars of your EnduroAge
Performance Capacity
Your aerobic engine and fitness age, from professional breath-by-breath VO₂ max testing and your personalised training zones.
Recovery Resilience
How well your body absorbs stress and bounces back — nerve-health, autonomic balance and readiness signals.
Body Composition
Muscle, fat and fluid mapped across your whole body, with visceral fat, metabolic rate and left/right balance.
Cardiovascular Profile
Heart age, cardiac efficiency, vascular age and arterial elasticity — the foundations of a long, strong life.
Lifestyle Alignment
How your sleep, training load, nutrition and daily habits line up with the results your body is showing.
The Longevity Scan
60+ clinical markers. The full picture of what your body is doing.
A precise, non-invasive standing assessment on our clinical-grade longevity scanning station — delivering a complete picture of your body composition and cardiometabolic health that most people can only access through specialist referral.
Body composition
Body fat %, muscle mass by zone, visceral fat, bone mass, total body water, basal metabolic rate and left/right balance.
Heart & cardiac function
Multi-lead ECG with atrial-fibrillation indicators, heart age, cardiac efficiency and reactivity, and standing heart rate.
Vascular & artery health
Vascular age, arterial elasticity and early arterial stiffness via pulse-wave velocity across the limbs.
Blood pressure & oxygen
Cuffless hypertension-risk indicators and SpO₂ blood-oxygen saturation.
Nerve & stress resilience
A nerve-health score and autonomic-nervous-system activity — how your body handles stress and recovery.
Metabolic & cellular health
Cellular age, glycemic-regulation score, intracellular hydration, cell-membrane integrity and metabolic efficiency.
Early-insight and performance signals — not a medical diagnosis.
Inside the Longevity Scan
Clinical precision, miniaturised.
The sensors behind your scan — the kind you won’t find in any bathroom scale — work together in a single guided assessment on the Withings BodyScan station at The Outpost, delivering clinical-grade data that used to require a specialist clinic visit.
Blood flow
Impedance plethysmography
Detects the change in blood volume within a limb with every heartbeat, by measuring how electrical resistance shifts as blood pulses through.
Body composition
Bioelectrical impedance
Sends multiple safe, low-level frequencies through the body to map muscle, fat, water and left/right balance across each segment.
Arterial health
Pulse wave velocity
Measures how fast the pressure wave travels along your arteries — an early, sensitive marker of arterial stiffness and vascular age.

Complete cardiovascular assessment
See your heart age — and what’s driving it.
Cardiovascular
Heart age
36 years old
▾ 2 years younger than your age
Illustrative example — your numbers are personal to your scan.
Detect what you can’t yet feel
Six-lead ECG screening surfaces indicators of atrial fibrillation and rhythm irregularities — often long before you’d ever notice them.
Assess the true age of your arteries
Vascular age and arterial stiffness, captured through pulse-wave velocity, show how your cardiovascular system is really ageing.
Understand your blood-pressure risk
Cuffless hypertension-risk indicators flag elevated pressure early — when small, sustainable changes make the biggest difference.
VO₂ Max & Training Zones
Your aerobic engine — measured, not guessed.
Professional breath-by-breath VO₂ testing during real movement, using a lightweight mask, with results the moment you finish. VO₂ max is one of the strongest predictors of long-term health — and the key to training in the zones that actually move you forward.
- ✓VO₂ max, maximum heart rate and a fitness-age interpretation
- ✓Aerobic (VT1) and anaerobic (VT2) thresholds
- ✓Automatically generated personalised heart-rate zones
- ✓Metabolic efficiency and running / cycling economy
- ✓Ventilation, breathing rate and ventilatory efficiency
- ✓Protocols matched to your goal — graded ramp, interval or resting metabolic test

Questions
Frequently asked
Is this a medical test?
No. EnduroAge is a wellness, longevity and performance assessment — it provides early-insight and performance signals, not a medical diagnosis. Always consult your GP for any health concern.
How long does it take?
Allow around 60–90 minutes for a full Pro assessment, including your Longevity Scan, VO₂ max test and time to talk through your results.
How should I prepare?
Avoid hard training, alcohol and heavy meals in the 24 hours before. Arrive hydrated, wear clothes you can move in, and bring access to your wearable or fitness-app data.
When do I get my report?
Your branded EnduroAge report is prepared after your visit and sent to you by email, with your score, top findings and a 30-day plan.
Do I need a wearable?
It’s not essential, but if you use a smartwatch or fitness tracker, sharing that data makes your assessment richer and more personalised.
Important — please read. EnduroAge is provided for general wellness, education and performance-coaching purposes only. It is not a medical assessment, diagnosis or treatment, and it does not replace advice from a qualified healthcare professional. Measurements and estimates reflect your results on the day of testing and may vary. Always consult your GP or a suitably qualified clinician before making significant changes to your exercise, nutrition or lifestyle, and seek medical advice for any health concern.
