Comeback Log

A weekly plan built around the equipment you have – from nothing but a floor, wall and doorway up to a full gym. It starts from your experience level, keeps things joint-friendly (with a low-impact-only switch in settings if you want it), and adjusts itself from your feedback after each workout. Tap ▶ Start on a day to be walked through it set by set, or How? on any exercise for full instructions.

Plan settings
Starting weak is the whole point of starting. Every exercise begins at a level that should feel almost too easy; the feedback buttons after each workout will dial it up at your pace.

Open-source fitness projects · credits & how to support them

Comeback Log is one local file: no accounts, no servers, nothing to pay for. Software like this is only possible because an open community shares exercise data and tools. Below: the project this app actually draws on, cited as a source, and neighbours worth supporting. Links open in your browser; the app itself never connects to anything.

Used in this app — source

free-exercise-db · 800+ exercises as public-domain JSON

Source credit: This app’s imported exercise entries trace to this dataset (the community “exercises.json” lineage): the advanced swap-only moves keep adapted text, and the rest have since been re-written in this app’s own words, keeping the movement facts. It’s released under the Unlicense, so no attribution is required — this credit is by choice, because the work deserves it. Honest caveat: the licensing of its image files is questioned in the project’s own issue tracker, which is why this app embeds none of them.

  • Report corrections and contribute cleaned-up exercise data upstream
  • Help chase down image provenance in the open issues — the whole ecosystem benefits

Not used here — but worth supporting

wger · self-hosted workout manager & open exercise database

A full open-source fitness platform (AGPL) with a community-maintained exercise database — descriptions, photos and videos under Creative Commons licenses, plus a free API. The most complete openly licensed exercise resource, and the best reference for double-checking form cues.

  • Star or contribute code at github.com/wger-project/wger — donation links live under the repo’s Sponsor button
  • Add or curate exercises on wger.de — submissions go through a moderation queue, so beginners are welcome
  • Translate it via Weblate

Everkinetic · CC-BY-SA exercise data with instructional drawings

Open exercise descriptions and simple how-to illustrations for the classic gym lifts, under Creative Commons BY-SA 3.0 — one of the few genuinely licensed illustration sets anywhere. Reusing it means giving credit and sharing alike; that attribution is the entire price.

  • Star the repo; fix or extend the data with a pull request
  • If you reuse the drawings, keep the credit intact so the license keeps working for everyone

Feeel · privacy-first workout app growing an open illustration set

An AGPL home-workout app that turns community-submitted exercise photos into its own low-poly illustrations. The healthiest long-term answer to “there are no openly licensed exercise images” is helping projects like this one make them.

Beyond code and money: star the repos so other people find them, answer a newcomer’s issue, or photograph one well-lit exercise for a project that needs it. Small contributions are what keep these commons alive.

General-fitness aid, not medical advice. If anything causes sharp joint pain repeatedly, drop it and get it looked at. Built around the public-health basics (US Physical Activity Guidelines for Americans, pre-2020; and WHO): about 150 minutes of moderate aerobic activity a week — or 75 minutes of vigorous — accumulated however it fits your day (later guideline editions confirmed even short bouts count), at least two strength days that cover all the major muscle groups, and a little flexibility, spread across the week with rest between hard days.
