A framework by Oliver Zaenkert · M.Sc. Sport Science & Coaching

The science of playing well for life.

Most golfers spend their later decades chasing the swing — and lose the game to a body that quietly stopped keeping up. I reverse the order: build the engine first, and the swing has something to stand on for thirty more years.

The Reality

Golf changes. So does the body.

What many golfers accept as the inevitable cost of getting older — less distance, more discomfort, a body that recovers slowly — is often not fate at all. It is the result of a body that was never deliberately prepared for the demands of a lifelong game.

Golfgevity was built to change that. It joins modern performance physiology, movement science and longevity research around a single goal: preserving your ability to play golf at a high level — not only today, but across decades.

Not a technique programme. Not a generic gym plan. Not a wellness add-on. A performance philosophy specific to golfers — tuned to the real demand of eighteen holes walked, weekly, for life.

The Diagnosis

What you notice first

Most golfers look for technical solutions to physical problems. They take lessons. They change the swing. They try new clubs. But with age, what fades first is rarely technique — it is the body underneath it. You feel it long before the scorecard does:

The swing suffers only after these do. Golfgevity therefore does not start with the club. It starts with the person.

The Framework

The five pillars

Neglect one and the other four cannot carry you. A lesson can only teach the swing your body is currently capable of — these five raise the ceiling on what is possible to coach.

The engine roomhalf the Golfgevity Score

Mobility

Free hips and a rotating thoracic spine are where both injuries begin and clubhead speed is found — the first quality to go, the cheapest to protect.

A swing that still turns at 70.

Strength & Power

Distance comes from developing force quickly. A resilient posterior chain as injury insurance, then the explosive, rotational power that fades fastest with age.

Endurance & Resilience

Eighteen holes walked is a genuine multi-hour endurance event. Cardiovascular capacity decides whether the back nine costs you strokes to fatigue.

Recovery

The body improves after training, not during it. Sleep, nervous-system regulation and objective markers like HRV decide whether training compounds or just accumulates.

Back on the course, fully charged.
15%

Nutrition & Metabolic Health

Performance begins at the cellular level: stable energy across eighteen holes, lower inflammation, durable long-term metabolic health — the fuel the engine runs on.

Steady energy, tee to clubhouse.
The Long Game

The same goal, played by decade

The goal stays constant. How you manage the body to protect it must evolve — and the earlier you start, the more there is to protect. The 40s are the highest-leverage entry point; every decade after is defending hard-won ground.

40
Build · highest leverage

Build the engine

The peak window to bank strength and power. Establish movement quality now and it carries forward for thirty years. Every quality you build here is something you won't have to claw back later.

50
Protect

Protect the power

Defend explosive output deliberately — it fades without a fight. Keep mobility honest and the posterior chain strong. Distance is still very much on the table at this stage.

60
Defend

Stay durable

Strength becomes injury insurance. Conditioning keeps eighteen holes comfortable rather than depleting, and recovery work decides how many quality rounds a week your body allows.

70
Play on

Keep playing

The whole point. A body trained for the long game is still on the course, still walking it, still enjoying it — playing the game you love on your own terms.

Proof of Concept

A living argument

The clearest argument for Golfgevity is a living one — a single set of biometrics from the person who built the framework, measured, not asserted. The gap between how old I am and how old my body performs is the whole thesis in one figure.

These are my numbers — age 56. Move any slider to see how the estimate responds. Or enter your own age and see where your fitness puts you. Don't know your HRV or VO₂max? Any HRV-capable smartwatch gives you both.

How it works: Cardiovascular fitness age is estimated from a fitness-age model using VO₂max, HRV and resting HR calibrated against established age-group norms — the same approach used in peer-reviewed longevity research. It's a heart-and-lungs figure, reported beside the whole-body Golfgevity Score, never in place of it. Not a clinical diagnosis. The same number is more significant at 60 than at 45, which is why the context line under each slider updates with your decade.

The Person Behind It

Oliver Zaenkert

Sports scientist · founder of Golfgevity

I built Golfgevity as a sports scientist, not a marketer. I hold an M.Sc. in Sport Science & Coaching, and I've spent my working life on the practical edge of performance — coaching athletes, screening bodies, and turning evidence into things people can actually do.

It grew out of one frustration: the golf world sells technique to bodies that can no longer execute it, and calls conditioning “wellness.” I treat the body as the performance asset it is — and I use my own as the standing experiment. At 56, my cardiovascular fitness tests at 42, and I coach that gap because I still live it. The work sits within Pergevity — my performance, fitness and longevity practice in Le Morne, Mauritius.

Start Here

Start with the number.

Every Golfgevity journey begins the same way — with one honest baseline. About forty minutes, five pillars, measured rather than asserted, and re-measured against itself every twelve weeks. Remote or in person. You know the full price before anything begins.

Two figures, kept deliberately apart

Golfgevity Score
0–100

The whole-body number, across all five pillars weighted. This is what the programme is built on.

Cardiovascular Fitness Age
vs your calendar

A single-system estimate from VO₂max and resting heart rate, after the published fitness-age models — the figure in the calculator above. Reported beside the Score, never in place of it.

A golfer can carry a young heart and stiff hips at once. Keeping the two figures apart is the only way both can tell the truth — and it keeps the whole body, not just the heart, in the number that drives training.

What gets measured

The full five-pillar battery — and how each piece is captured. Almost all of it remotely; in person adds the hands-on screening.

Then, every twelve weeks.

You're re-tested against your own baseline — distance held or won back, pain down, energy through eighteen, the Score moved. If the numbers don't move, the programme changes, not you.

These are field estimates, not laboratory values — VO₂max from a watch, power from a phone's flight-time read. They carry error, and that's the point: the job is not one perfect number but a faithful baseline the same body can be measured against twelve weeks later. None of it is a medical diagnosis.
Work With Me

Three ways to put the framework to work

Each starts with the same principle — the body first — and scales from one player to a whole club.

01
Individuals

Signature Assessment

Every journey begins with clarity. A structured evaluation of movement quality, strength potential, endurance, recovery and lifestyle factors. You emerge with a transparent, measured personal roadmap — exactly what to train, what to protect, and why. Remote or in person.

02
Golfers, 40s+

Performance Programme

One-to-one coaching built around your own assessment — programmed for the golfer you intend to still be in twenty years. Best begun in your 40s or 50s, while there's most to bank, but it works whenever you start. Objective tracking throughout, from clubhead speed to HRV. Remote or in person.

03
Clubs & member groups

Club Workshops

A club's most committed members are often its oldest — and the first to play less as the game gets physically harder. A workshop gives them the evidence and the five-pillar playbook to keep playing well for years longer — a distinctive member benefit, and a direct lever on retention.

How It Works

From first message to measurable change

No sales funnel, no lock-in — a baseline, a plan, and proof it's working.

01

A real conversation

You write, I reply — personally. We talk about your game, your body and what you're after. If I'm not the right fit, I'll say so. Free, no obligation.

02

Signature Assessment

A structured baseline across all five pillars. You get the findings in plain language — what to train, what to protect, and why.

03

Your programme

Built in twelve-week blocks around your assessment and your schedule, with structured check-ins. You know the full price before anything starts.

Re-measure

Re-tested against your own baseline — distance held or won back, pain down, energy through eighteen. If the numbers don't move, the programme changes.

Every 12 weeks — back into your programme
The Vision

A new category

Golfgevity is not a fitness programme. It is a new category — a meeting point of golf performance, longevity science and coaching practice.

The goal is not to live longer. It is to live capable for longer — and to keep enjoying the game you love.
Play well. Stay strong. Keep going.
