Sport came first. Long before the spreadsheet.
I have been training since I was a kid. Judo first, then karate, then boxing — and more than eight years of MMA after that. Different sports, same lesson every time: the people who get better are the ones who keep track of what they actually did, not the ones who remember it the way they wish it had gone.
Martial arts teach you to be exact about small things. A hand that drops two inches. A week you told yourself was hard and was not. That habit is the whole reason this system exists.
I got tired of juggling apps.
Training in one app, food in another, notes somewhere else. Every one of them wanted a subscription, an account, and a say in what happened to my own numbers. So I built the thing I wanted instead: one file where training, nutrition and progress sit together and the maths happens by itself.
It was built for one person — me — and refined over hundreds of mesocycles before it was ever offered to anyone else. Nothing in it is theory that has not been run.
No certifications on the wall.
There are no coaching qualifications here and no supplement sponsorships. I am not selling a transformation, a guarantee or a shortcut. What is for sale is the system I use, in a file you keep.
Which also means I will not tell you it works for everyone. It works if you log what you lift and eat roughly like you planned to. That is the whole deal.
Your log should outlive the tool.
Tools change and companies pivot. A training log is one of the few things worth keeping for a decade, and it should not be hostage to whether some company is still around. So the spreadsheets are bought once and they stay yours — no account, nothing to renew, nothing that can be switched off from a distance.
The app is the one exception, and it says so plainly: that is a subscription, because an app is a service that has to be kept running. The files are not, and never will be.
