Argilzar Workouts

A workout product that grew out of a real Usable chat logging workflow and turned those logged sessions into a dedicated local-first app.

Overview

Argilzar Workouts did not begin as a blank-slate app idea. It came from an already useful Usable chat workflow for logging workouts, then turned that workflow into a dedicated interface with programs, workout execution screens, summary/history views, and a cleaner product memory trail.

Why this project exists

The project exists because chat was good enough to prove the habit but not good enough to be the final interface. The most valuable part of the earlier workflow was that Usable chat created real logged sessions that later became product evidence, PRD material, and implementation priorities.

What was built

  • A local-first workout app backed by IndexedDB/Dexie
  • Program library, workout logger, summary, and history views
  • Dedicated support for skip flows, substitutions, and supersets

Project scope

The project keeps a clear product stance: use the app UI for fast execution and keep intelligence in the surrounding workflow. That is why the current app stays local-first and why the longer-term direction includes keeping Usable chat in the loop for planning while a dedicated UI handles actual workout execution.

Development log

The writing around Argilzar Workouts is most interesting when it shows how logged sessions, Usable chat, Hermes orchestration, and a local-first architecture turned into a real product.
