The Science

Built on evidence, not optimism.

Longevity has a real, growing science. We anchor everything we do to the metrics with the strongest links to a long, healthy life, and we're honest about where the evidence ends.

The thesis

Healthspan is trainable

The leading causes of death today, things like cardiovascular disease, metabolic disease, cancer and neurodegeneration, all develop over decades. They leave a measurable trail long before they become a diagnosis.

That's the opportunity. The same biology that predicts decline can be measured today and shifted with the right inputs: aerobic training, strength, metabolic health, sleep and targeted nutrition. Longevity isn't about a single miracle. It's about getting the boring, high-leverage fundamentals right, and then verifying them.

The science of longevity
The high-leverage markers

Four numbers worth defending

These aren't the only things we track, but they're the ones with the strongest evidence and the most room to act.

VO₂max

Cardiorespiratory fitness is among the strongest predictors of all-cause mortality ever studied. Moving up even one fitness category is associated with a substantial reduction in risk. And unlike a lot of markers, it responds quickly to training.

ApoB & lipids

ApoB counts the atherogenic particles that drive cardiovascular disease, the world's leading killer. It's measurable, it's actionable, and the earlier it's managed, the more years it protects.

Lean mass & strength

Muscle is metabolic armour. Strength and lean mass track closely with independence, fall risk and survival in later life, and you build them on purpose, never by accident.

Metabolic health

Insulin sensitivity, glucose control and inflammation sit upstream of most chronic disease. Catching dysfunction early, while it's still reversible, is one of the highest-leverage moves in longevity.

Where it comes from

Standing on established shoulders

Our protocols draw on the modern canon of longevity and lifestyle medicine.

01

Longevity medicine

Train for the demands of your final decades: manage cardiometabolic risk early, build a deep reserve of strength and aerobic fitness, and personalise every decision to your own data.

02

Lifestyle medicine

Evidence-based pillars from Harvard-aligned lifestyle medicine: movement, nutrition, sleep, stress and connection as primary interventions.

03

Exercise physiology

ACSM-aligned training science for cardiorespiratory fitness, strength and recovery, applied, measured and progressed.

Research integrated practice
A learning practice

Every member's data makes the next protocol smarter.

What we don't claim

We don't promise to reverse ageing, cure disease or replace your physician. Biological-age and neuro-state outputs are directional models, not laboratory diagnoses. What we do promise is rigour: real measurement, honest interpretation, and a plan that's corrected on evidence every 45 days.

References to Harvard lifestyle medicine, ACSM guidelines and Blue Zones research describe the bodies of work that inform our approach; they do not imply endorsement or affiliation.
