Science-backed health for life after 40
Ireland's first health optimisation service for adults over 40 who want to take charge of their energy, fitness and aging process. No fitness level required, just a decision to start.
Ireland's first science-backed longevity service
The Longevity Lab is built for adults over 40 who want to take charge of their energy, fitness and how they age. Whether you're feeling low on energy, trying to get your health back on track, or simply want to feel better in your body as the years go on, this is designed for you. No fitness level required, just a decision to start.
It's a complete testing programme that measures your VO₂ max, resting metabolism, training efficiency and lung function, then turns the results into a clear, personalised roadmap for your health, fitness and recovery. We take clinical-grade tools that were once reserved for elite athletes and make them useful for real people living real lives.
VO₂ max is one of the strongest predictors of lifespan
Improving your VO₂ max by just 10–20% can slash your risk of all-cause mortality by up to 70%. That's a bigger benefit than quitting cigarettes or losing weight. Low VO₂ max is linked to early death from heart disease, cancer and dementia, because it reflects your body's ability to resist cellular decay.
A VO₂ max below 20 mL/kg/min (common in sedentary adults) = mortality risk similar to stage 4 cancer. Low VO₂ max ages your body internally 20+ years faster.
Top-quartile VO₂ max vs bottom-quartile, all-cause mortality.
The four numbers that shape how you age
Every package below is built from these four tests.
VO₂ Max
Your aerobic fitness score, directly linked to cardiovascular health and longevity.
Blood Lactate Threshold
Identifies your ideal training intensities for fat-burning, endurance and recovery.
Resting Metabolic Rate
Measures how many calories your body burns at rest. The foundation of smart nutrition.
Spirometry
Measures lung function, a key indicator of long-term health and vitality.

The science behind it
The Three Biggest Indicators of Longevity: Strength, Muscle Mass and VO₂ Max
