Exercise illustrations and data

From RepDB, used under its free-tier licence, which permits commercial use inside an application with attribution:

Exercise data by RepDB (repdb.co)

The two terms that grant that use and set its condition, quoted from the licence:

1. Free for personal and commercial use inside applications. You may use the dataset and images inside applications — apps, websites, research projects — for personal and commercial purposes, at no cost.

2. Attribution required. Place a visible link — “Exercise data by RepDB (repdb.co)” — in your app’s about/credits screen, your project’s README, or your website footer.

# RepDB — Free Tier License (v1.0)

**This license covers the RepDB free-tier exercise dataset (JSON) and associated WebP image assets distributed in this repository.**

## Tier scope

**Free** — every fully illustrated exercise in the RepDB catalog, with flat-style images, for personal or commercial use inside applications, with attribution.

For 1024px images, the classic image style, transparent backgrounds, animated exercises, or commercial use without attribution, upgrade at https://repdb.co/pricing.

**About this repository.** This repository is the canonical free-tier distribution published by RepDB itself. Term 3 (no redistribution as a dataset) binds third parties — it does not restrict RepDB's own publication here, on Kaggle, or on Hugging Face. Forks made for the purpose of contributing back are fine; republishing a fork as your own dataset is not.

## Terms

1. **Free for personal and commercial use inside applications.** You may use the dataset and images inside applications — apps, websites, research projects — for personal and commercial purposes, at no cost.

2. **Attribution required.** Place a visible link — "Exercise data by RepDB (repdb.co)" — in your app's about/credits screen, your project's README, or your website footer.

3. **No redistribution as a dataset.** You may not republish, resell, or repackage the dataset — or a modified or derived dataset — as a dataset, dataset repository, or API. In-app use only.

4. **Image modifications.** Images may be resized, cropped, or recolored for in-app use. Upscaled or background-removed derivatives fall under the same no-redistribution rule (term 3).

5. **No generative-AI derivation.** The images may not be used as input, reference, or conditioning material for generative models — image-to-image restyling, style transfer, model fine-tuning, or similar — whether to recreate the artwork in another style or to train models on it. Outputs of such processes count as derived datasets under term 3 and may not be used in applications or redistributed.

6. **Paid-tier preview animations are evaluation-only.** The looping exercise animations included as paid-tier previews — the same clips shown on https://repdb.co, provided so you can evaluate the paid-tier quality — may not be used in production applications or redistributed. Terms 1–2 do not extend to these preview animations, wherever they appear in this distribution (e.g. the `premium-samples/` folder).

7. **No warranty; not medical advice.** The dataset is provided "as is" without warranty of any kind, to the extent permitted by law. To the extent permitted by applicable law, RepDB's liability for damages arising from use of the data is excluded. This exclusion does not apply to liability for injury to life, body or health, to intent or gross negligence, to claims under the German Product Liability Act (Produkthaftungsgesetz), or to any other liability that cannot legally be excluded. Exercise content is informational and not medical advice; consult a physician before starting any exercise program. Users perform exercises at their own risk.

## Origin of the data

The dataset was compiled independently by RepDB. All images are original works generated with AI tooling commissioned by RepDB — not copied or derived from any third-party exercise dataset or image library. The dataset's structure and selection are protected as a database (sui generis database right, §§ 87a ff. UrhG) independently of the copyright status of individual images.

## Licensor & contact

RepDB is operated by Sergei Argutin, Regener Str. 51, 10318 Berlin, Germany.

Machine and cable illustrations

Ten movements — the selectorised row, the reverse pec deck, the cable woodchop and seven others — are drawn by Workout Guide by Bryl Lim, used under CC BY-SA 4.0. Its upstream pose artwork is by Everkinetic, under the same licence.

Workout Guide visual assets are licensed under the Creative Commons Attribution-ShareAlike 4.0 International license (CC BY-SA 4.0).

You may share and adapt these assets for any purpose, including commercially, provided that you give appropriate credit, link to the license, indicate changes, and distribute adaptations under the same license.

Changes we made: each drawing is a single white shape on a transparent background. We recoloured that shape to this app’s ink tone and placed it on the same pale ground the other illustrations use, then saved it at 512×512. Nothing was cropped, reframed or redrawn. Those adapted images are offered under CC BY-SA 4.0 in turn.
