A scientific engine + an AI judge

Volume, the pull-to-push balance, progression and the deload are computed by a deterministic engine. The model joins at the end — it checks the calculation and rewrites the descriptions.

How it works

The engine calculates. The model checks. You edit.

01

A deterministic engine

Volume per muscle group, the pull-to-push balance, progression and a deload across the cycle. The same input gives the same plan.

02

The AI judge

The model does not assemble the plan and does not change the numbers. It checks the finished calculation against its own rules, rewrites the descriptions and flags what is arguable.

03

The week board

Seven columns, exercises dragged between days, the inspector on the right. A mouse does what takes five taps on a phone.

04

No “Save” button

An edit applies at once. In the phone app and in the desktop client it waits in a queue until the connection is back.

05

The runner

Big set numbers, fact against plan, the day's queue and keyboard shortcuts. The phone in the gym, the browser at home.

How a plan comes together

Watch the week assemble

  1. 01

    The engine lays out the week

    Days, the split and volume per muscle group — by the rules of training science, not by inspiration.

  2. 02

    The judge checks the calculation

    Does the balance add up, are the limitations respected, are there two heavy days in a row. It never touches the numbers.

  3. 03

    You move whatever you like

    Drag a workout to another day — the edit applies at once, with no “Save” button.

Planning

The whole week on one screen

A seven-day board instead of a calendar on a phone: volume, duplicates and a skew across muscle groups are visible at once. An exercise is dragged between days, and the inspector edits sets without leaving the board.

  • Drag & drop between days
  • The ⌘K command palette
  • Print and PDF on A4

The days a week decide the split

  • 2 days Full body
  • 3 days Full body
  • 4 days Upper / Lower
  • 5 days Push / Pull / Legs
  • 6 days Push / Pull / Legs

Progress

The goal decides what to count

For strength it is the working weight and the records, for endurance it is pace and duration. The page rebuilds itself around the goal instead of showing everyone one tonnage table.

  • Its own set of metrics for every goal
  • Apple Health and Google Health Connect
  • Plan against fact for every set

The goals the page rebuilds itself around

  • Strength Fewer reps, longer rests
  • Muscle gain More volume, supersets in the main work
  • Fat loss Circuits and cardio finishers
  • Endurance Long sessions, intervals, heart-rate control

Frequent questions

How is this different from “an AI made me a plan”?

A deterministic engine plans by the rules of training science: weekly volume inside a corridor for every group, the pull-to-push balance, progression with a deload. The model joins after the calculation, as a reviewer. That is why the same profile always gives the same plan instead of a new fantasy on every request.

Do I need a phone if I have a browser?

No, but the two are better together. Planning the week and reading progress is easier in the browser; the gym is for the phone. The data is shared: whatever is built in the browser is on the phone straight away.

What if I have an injury or little equipment?

Equipment and limitations are set in the profile. The engine leaves out dangerous exercises and substitutes alternatives, and the plan shows exactly what was replaced and why.

Does it suit cardio and mobility?

Yes. Beyond the strength profile there are intervals, steady cardio, running by pace, static holds and circuit finishers — each with its own fields rather than one universal form.
