Your business grew. Your body picked up the tab.

One Life is the Chief Health Officer seat for the person carrying the company. I rebuild the energy, sleep, strength and stress system underneath your calendar, the way a fractional CFO runs your books.

Fifteen minutes. Three sharp questions. A straight read and a clear next step, either way.

The True Cost

You hold every system in the company to a standard. Except the one running you.

The 3pm crash you didn't have at 35.

Sleep that's "fine" but never restorative.

Recovery that takes three days instead of one.

You're still winning. You're winning slower.

This was never a discipline problem. You simply never pointed the operating system you run the company with at your own physiology. Every other asset gets a dashboard, a review, someone accountable. The body carrying all of it gets none. And it's the only asset that decides how long you get to enjoy the rest.

The Method

Four pillars. Built to a depth most people don't know exists.

The industry has 400 things you "must" do. We have four. Built properly, they predict over 80% of how you feel, perform and age. Anything beyond is decoration.

Pillar 1

Movement

Strength three times a week. Cardio twice. Daily walking and mobility. Programmed against your body and your calendar. Never a template.

Pillar 2

Real Food

Protein-anchored, plant-supported, three meals. No counting, no restriction theatre. A way of eating that survives month three and the client dinner.

Pillar 3

Sleep

Seven to nine hours, consistent window, engineered environment. The cheapest legal performance drug on earth, and the first thing leaders sacrifice.

Pillar 4

Stress

Stress isn't avoidable. It's the job. We build the discharge: breathwork, deliberate recovery, boundary engineering on the calendar itself.

The Promise

Your body should never be the reason you say no.

Four outcomes the work is built to deliver. None of them aesthetic. All of them operational.

Energy · 20–40%

Sharp through 6pm. Without coffee.

The 3pm crash dissolves. Recovery from travel and high-stakes weeks goes from days to hours.

Composition

Visceral fat down. Lean mass up.

Measurable recomposition without obsession. Strength benchmarks retested every quarter.

Sleep & HRV · 20–30%

Restorative, not just long.

Deep and REM sleep up. HRV trending up. The system gets cleaner; the numbers follow.

Capacity

Still running this at 65.

The strength, recovery and durability to operate at full capacity for the next twenty years, not just survive them.

How It Works

You bring the calendar you actually have. The system is built to survive it.

01

The diagnostic

Fifteen minutes. Three sharp questions, a straight read on your #1 leak, and an honest answer on fit, both directions.

02

The protocol

A personal system across the four pillars, built for your real life: the travel, the dinners, the board weeks. Delivered within 7 days.

03

The calibration

Structured check-ins, direct access between them, adjustments against your data. The system travels with you. And compounds.

The Work, In Their Words

Fifteen years with high performers. Founders, CEOs, and royalty among them.

Fit

Built for the person carrying the company.

This is for you if

  • You've built or run something real: a company, a fund, a firm, a P&L. Your decisions carry other people's livelihoods.
  • You've already won at most things, and quietly recognize your body is no longer winning.
  • You've tried trainers, apps, retreats. None of it stuck, because none of it was built for the load you actually carry.
  • You want the role filled: one person accountable for the asset everything else runs on.

This is not for you if

  • You're chasing abs and an after-photo. Someone else's right client.
  • You want daily hype, hand-holding, or a guru.
  • You'd weigh this against a gym membership.
  • You want gadgets and complexity. We sell the opposite, and we hold that line.
The Founder Behind It

I live the calendar I coach.

Cassio Oliveira, founder of One Life

I run three businesses across the Pacific: this practice, a restaurant in Nouméa that burned down and was rebuilt from the ground, and a hospitality portfolio between New Caledonia and Brazil. Three languages, five time zones, a family. I know what a founder's day costs the body, because I pay for it myself.

The formal depth underneath: Level 4 Personal Training in Australia, the country's highest qualification · formal grounding in sports science · clinical experience in Chinese medicine · advanced nutrition certifications · CF-L2 · 15+ years across 8+ countries on 5 continents · featured in Brainz Magazine. West taught me to measure the body. East taught me to read it.
"I rebuild founders' bodies so their companies don't collapse with them."

Straight Answers

What you're probably weighing right now.

I'm already working 60-hour weeks. How much time does this take?+
The whole thing is built for no time. Sessions run 45–60 minutes, check-ins take minutes, and the protocol is engineered around your existing calendar, never against it. If time were the fix, you'd have fixed this already. The gap was never hours; it was a system built for your actual life.
I travel constantly. Does this survive the road?+
It's designed for it. You get a travel protocol built for real conditions: hotel gyms, airport food, time zones, stakeholder dinners. A week on the road with three short sessions and daily walks is a win, not a setback. The system is built to survive travel, because your life includes it.
I've tried trainers and diets before. What's different?+
Trainers hand you workouts. Nutritionists hand you meal plans. Those are tactics without a strategy, and none of them were built for the operational load you carry. A Chief Health Officer runs the whole system: movement, food, sleep, stress, as one integrated protocol, calibrated against your data and your reality. You never failed at fitness. You never had this.
What's the actual return?+
Two balance sheets. Yours: energy through 6pm, a body that recovers, strength that holds for the next twenty years. The company's: sharper decisions, more capacity, and a key-person risk that stops compounding quietly. You already know what the current state costs you every year. This is a fraction of one bad quarter from the person the company runs on.
What does it cost?+
It's a serious engagement, priced accordingly, and I state the number plainly on the call. One number, no games, no pressure tactics. What I can tell you before we speak: every tier costs a fraction of what one bad quarter costs the company when the person running it is operating at sixty percent.
Do I have to give up business dinners and my social life?+
No. A protocol that can't survive a client dinner isn't a protocol. It's a countdown. You get the playbook for any restaurant, any event, any city, so the work holds without you becoming the person counting calories at the table.

Health compounds. Or it decays.

There is no neutral ground. Fifteen minutes gets you a straight read on where you stand, and what it costs to leave it.

Fifteen minutes. A straight read, either way.
