Hi, I'm Jason

I built this body from the worst starting point I could have asked for.

Narrow shoulders, long limbs, wrists you can wrap two fingers around, and strength that started at zero.

Me at fifteen, before any of it
What this is

The Zero-to-One Handbook

I took the whole process — learning, training, eating, tracking, adjusting — and turned it into a system. You run it with your own numbers, and build the training and diet around you.

If you've never trained before, the hardest part isn't the gym. It's that nobody tells you where to start — so you watch a hundred videos, get a hundred answers, and never begin.

This handbook is the starting point. You read it alongside any free AI chatbot, copy the questions in the order they're given, and by the end you have a coach that knows your body, your schedule and what you're working with — and tells you exactly what to eat, what to lift, and when.

No gym experience needed. No subscription. One afternoon to set up, and it's yours to keep.

Who I am

Hi, I'm Jason.

My name is Jason. I was the skinny one — always. The kid who ate everything and stayed a stick.

I came to Toronto alone at 15 — barely spoke English, no friends, no guidance, had to figure everything out myself. Desperate to fit in the new culture and make a change, I landed on bodybuilding with zero idea what I was doing in the gym.

There was no guide available, so I did it the only way I knew — try something, run it, watch what my body said back, adjust. Ten years of that. Eight of them actually training. All natural: protein powder and creatine, nothing else.

I built to my biggest, lost it during lockdown, cut it back down, and built again. Every phase taught me the same thing: the plan was never the hard part. Knowing which question to ask next was.

This handbook doesn't take the trial and error out — that is the method. You'll still be running it, on your own body, because that's the only way anyone finds out what works best for them. What it gives you is a system and a direction, so you get there faster.

If it worked on a frame genetics didn't hand me, it can work on yours.

The credential
ISSA certified personal trainer certificate

I'm a certified personal trainer through the International Sports Sciences Association.

What I have to share

So I wrote down the part that actually mattered.

Not the workouts. You can find those anywhere, free, explained better than I could explain them.

What nobody hands you is the sequence — which question to ask, in what order, and how to read the answer your own body sends back. That is the part that took me ten years to learn the slow way, and it is the only thing I have that is genuinely worth passing on.

So that is what I built. Not my program — you don't want my program, you have a different body. The questions.

The real problem

Why didn't the last one stick?

The program from YouTube worked — for the guy who wrote it. The meal plan lasted three weeks. The coaching app charged you every month to feel like you were falling behind. None of them ever asked a single question about you: your body, your schedule, your recovery, the way you actually eat.

And the truth nobody selling fitness will say out loud: information was never your problem. Arnold's Blueprint is free on YouTube. Every exercise has a thousand perfect tutorials. If information built bodies, everyone at your gym would be built. What's missing is a system you can actually stick to — one built so tightly around your real life and your habits that showing up stops being a daily decision. The truth is, real transformation takes months and years. The only way to get there is to find something you can keep doing for that long — and to keep adjusting it as your body changes.

Here's what a decade in the gym taught me: generic plans die on contact with a real life. The only system that survives is one built around your own data — and until now, building one meant years of trial and error, done by hand. Mine.

The method

No coach can guess it. No template contains it. Your body has to be asked.

I've trained beside guys who grew on six days a week of brutally heavy weight — and guys with even better physiques who only trained three days a week, lifting half of it. Both worked, because the exact exercise, the volume and the routine were never what decides. The system built around the person, and around how their body responds, is. Your body already knows what works for it — your own data is how it tells you. This teaches you how to listen.

Which is exactly why I'm not handing you my plan. The whole point of this is to help you build your own — the one that fits your body, your week and your equipment, not mine. The AI does the part I had to do by hand for ten years: it takes what you tell it, works out what that means for you specifically, and keeps adjusting as your own data comes in. You end up with a plan nobody could have written for you in advance, because it was built out of you.

01

Ask

The right questions, in the right order. You don't get handed an answer — you get walked to your own.

02

Observe

Fifteen seconds a day. Training, weight, food. Real numbers off your real week, not what you assume.

03

Adjust

Every four weeks the coach reads the whole month and changes the plan. Then you go again, sharper.

What's inside

One handbook. A system you keep.

Copy the prompts into ChatGPT — or Claude, or Gemini — in the order they're given. By the end you have a coach that knows your body and a loop that keeps it that way. No subscription. Nothing to install.

The companion app

The tracker that runs the loop.

The handbook builds your coach. The app is where you feed it — training, meals and weigh-ins in a few seconds a day, then the monthly check-in when the month is up.

It runs in your phone's browser — nothing to install, no account with me, free. Read the handbook first: the app needs the plan the handbook builds.

Open the tracker

Why you're here

What I'm actually asking you for.

If you've tried it, tell me what you honestly think. Not to be nice — to be useful.

What should be better? Where did you get stuck, or have to read something twice, or put it down and not come back?

And tell me about you. What you're trying to change, what has made that hard so far, and what you still want to know. If there's a part of the last ten years I haven't written down and you'd find it useful, ask me for it — that's how I'll know what to build next.

Questions

Straight answers.

Why not just ask ChatGPT yourself?
Because ChatGPT will answer anything you ask — but a beginner doesn't know what to ask. Ask it to build a plan and you get a generic one-shot answer with no idea what it skipped. Ask twice, get two different plans. This is the sequence — the right questions in the right order, each building on the last. The prompts are free to copy. Knowing the order took ten years.
Who is this for?
Adults 18+ who've tried things and nothing stuck. Skinny and can't gain, carrying extra fat and can't lose it, coming back after years off — the Router reads where you are and builds your path. What matters isn't your body type. It's that you're done running other people's plans.
What if it turns out this isn't for me?
Then it should tell you, and it does. If your numbers say a deficit is the wrong idea — or you answer yes to the screening question about your relationship with food — the coach refuses to build you one and points you somewhere better. That's a safety net, not a diagnosis, and it's deliberately hard to talk past. A system honest enough to tell you when it isn't for you is worth more than one that says yes to everybody.
Do I need a paid AI subscription?
No. Free ChatGPT works. Claude and Gemini work too. It teaches the method, not a product.
Do I have to track my food?
You log meals in whatever food app you like — Cronometer is the default suggestion — and once a week you screenshot its summary and hand it over. You never retype a number. The tracker app does the same job if you'd rather keep everything in one place. And if you'd rather not track at all, there's an honest fallback: eat consistently, hit your protein, tell the coach you're not tracking, and let your weight trend carry the signal.
Is this a workout program?
No — and that's the point. Programs are someone else's answers. This is a system for building your own coach: training, nutrition and recovery built around your body and your data.
Is this medical advice?
No. This is educational content for adults 18+, based on personal experience and an ISSA personal training certification — not medical, dietetic, or health-care advice. Talk to your doctor before starting any training, nutrition, or supplement change.
