Longevity
Cardiorespiratory fitness, muscle mass, strength and balance are among the strongest modifiable predictors of healthspan. We train all four.
- VO₂max
- Grip & leg power
- Balance
- Body composition
Research-led training lab
Train by evidence.
Age by design.
We read the science on longevity, strength and endurance, turn it into protocols you can follow, coach you through them and measure what changes.

Research digest
The science, minus the noise.
Every summary covers what was studied, what was found, how strong the evidence is and what it means for your training.
Cardiorespiratory fitness and all-cause mortality: no upper limit found
Higher treadmill-measured fitness was associated with lower long-term mortality in over 120,000 patients. The top performers had the lowest risk.
SO WHAT → Treat VO₂max as a vital sign. Test it, then train it.
Mandsager et al. · JAMA Netw Open · 2018
4×4 intervals beat steady work for VO₂max
With total work matched, 4-minute high-intensity intervals raised VO₂max more than moderate continuous training.
SO WHAT → 1–2 interval sessions weekly on top of a Zone 2 base.
Helgerud et al. · Med Sci Sports Exerc · 2007
More weekly sets, more muscle, up to a point
A graded dose-response between weekly set volume and hypertrophy.
SO WHAT → Aim for 10+ hard sets per muscle per week and build up gradually.
Schoenfeld et al. · J Sports Sci · 2017
30–60 minutes of strength work per week, lower mortality risk
Muscle-strengthening activity was linked to lower risk of death and major disease, with the strongest effect when combined with aerobic activity.
SO WHAT → Lift 2–3× per week and don't skip the cardio.
Momma et al. · Br J Sports Med · 2022
Elite weightlifters carry record amounts of fast-twitch fibre
Thigh biopsies from World, Olympic and national-level US weightlifters showed about two-thirds pure type IIa fibres, the highest ever reported in this muscle. World-class women averaged 71%.
SO WHAT → Rapid force comes from fast-twitch fibre. Keep heavy and explosive lifts in your week.
Serrano et al. · PLoS One · 2019
Identical twins, 30 years apart in training
At 52, the endurance-trained twin had a 12.4 ml/kg/min higher VO₂max, 8.6% lower body fat and 55% more slow-twitch fibres, but less muscle size and strength than his untrained brother.
SO WHAT → Genes set the starting line, not the finish. Pair endurance with strength work to keep both.
Bathgate et al. · Eur J Appl Physiol · 2018
The first four weeks predict who is still training a year later
Only 10% of beginners in a fitness app still trained weekly after 12 months, and the median dropout came at week 19. Consistency in the first 28 days was the strongest predictor of sticking with it.
SO WHAT → Make month one about showing up regularly, not about perfect sessions.
Conti et al. · Front Sports Act Living · 2026
Women build muscle at the same relative rate as men
On identical programmes, men gained slightly more muscle in absolute terms, mainly in the upper body. Relative to starting size, gains were the same.
SO WHAT → Same principles, same programme. No special “female” hypertrophy plan needed.
Refalo et al. · PeerJ · 2025
Nightly HRV swings mirror your habits
Across about 2 million nights from wearable users, larger day-to-day swings in HRV went with more alcohol, less activity and shorter, irregular sleep. Five nights a week gave a reliable estimate.
SO WHAT → Watch how stable your HRV is, not one morning’s number. Fix alcohol and sleep first.
Grosicki et al. · Am J Physiol Heart Circ Physiol · 2026
Whole eggs vs egg whites after lifting
Trained young men ate 3 whole eggs or 6 egg whites (same protein) after every session for 12 weeks. Muscle grew equally, but the whole-egg group gained more grip and knee-extension strength and lost more body fat.
SO WHAT → Total protein drives muscle growth. No need to throw away the yolk.
Bagheri et al. · J Strength Cond Res · 2021
Ice on the neck between rounds: feels easier, same output
Wet ice on the back of the neck during 1-minute breaks between hard cycling rounds lowered skin temperature, heat sensation and perceived effort. Time to exhaustion did not change.
SO WHAT → A cheap comfort tool for hot, repeated efforts. Don’t expect a performance boost.
Galpin et al. · Sports (Basel) · 2016
16:8 eating while building muscle: it works, with trade-offs
Trained men and women in a 10% calorie surplus with 2.2 g/kg protein gained as much lean mass in an 8-hour eating window, with less fat. But training volume, energy and squat 1RM gains were lower.
SO WHAT → Time-restricted eating fits a muscle phase. If top-end strength is the goal, a wider window may serve you better.
Blake et al. · J Int Soc Sports Nutr · 2025
Up to half of tested supplements contained banned substances
Lab analyses found anabolic agents or other prohibited substances in 14–50% of sampled sports supplement products.
SO WHAT → Buy third-party certified products, stick to the label dose and watch for overlapping ingredients.
Jagim et al. · Front Sports Act Living · 2023
Being unfit carried more risk than any cardiac risk factor
In 750,302 US veterans aged 30–95, followed for a median of 10 years, the least fit fifth had about 4× the mortality risk of the fittest. The pattern held for men, women, all races and people in their 70s and 80s.
SO WHAT → It is never too late to move up a fitness category. Each step down the ladder costs years.
Kokkinos et al. · J Am Coll Cardiol · 2022
Grip strength predicted death better than blood pressure
Across 17 countries, every 5 kg lower grip strength meant about 16% higher all-cause mortality. Grip was a stronger predictor of all-cause and cardiovascular death than systolic blood pressure.
SO WHAT → Test your grip once a year. Carries, hangs and heavy pulls keep it high.
Leong et al. · Lancet · 2015
Lactate shows how well you burn fat
Pro endurance athletes burned far more fat and made less lactate at the same workloads than moderately active people or people with metabolic syndrome. The lower the lactate, the higher the fat oxidation.
SO WHAT → This is the logic behind Zone 2: steady work just below the point where lactate starts to rise.

Principles
- 01
Evidence over trends. Every recommendation cites its source and evidence level.
- 02
If it matters, measure it. Every program starts with a baseline and ends with a re-test.
- 03
Principles are universal. Programs are personal.
- 04
Open by default. We publish our own results, including when they prove us wrong.
