ExerciseBank tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • get_exercise

    The full record for one exercise id: description, coaching cues, French, classification, which media exists.

  • get_media_urls

    Short-lived signed URLs (video clip and still) for up to 50 exercise ids, issued for the person named in EB_END_USER. They expire, 15 minutes by default: show them now, store exercise ids. A sandbox key gets media only for the ids in get_vocabulary.sandboxMediaSample.

  • get_substitutes

    Ranked replacements for one exercise, each with a score and the reason it works as a swap. Filter by the gear the person has and by joints to avoid.

  • get_vocabulary

    The exact values the ExerciseBank filters accept: muscles, equipment, movement patterns, joints, impact. Call this once before search_exercises or get_substitutes. Also returns the catalogue version and the ids a sandbox key gets video for.

  • search_exercises

    Search 1,492 studio-filmed exercises. Every filter is optional and they combine. Only exercises returned here exist: never invent an exercise or an id. Without q the order is alphabetical, so filter rather than page.

ExerciseBank examples

ExerciseBank is an exercise library for developers of fitness, coaching, physiotherapy and AI-trainer apps: 1,492 exercises filmed with real people in one studio, each with a looping video clip, a start/end still, a hand-checked classification (muscles, equipment, movement pattern, difficulty, loaded joints, impact), coaching cues, English and French, and a ranked map of which exercises can replace which. One REST API, JSON, a free sandbox key with no card.

This repository is working code for it.

Get a key

https://exercisebank.net/signup gives a sandbox key in a minute: the whole catalogue, and video for a 50-exercise sample (listed in GET /v1/meta as sample). The examples read it from EB_KEY.

export EB_KEY=eb_live_…
node node/quickstart.mjs

Four rules of an integration

an exercise has ({ "mp4": true, "still": true }).

  1. Call from your server. The key never ships in an app binary or a web bundle.
  2. Search, detail, substitutes and the catalogue return data only. media there says which assets

X-End-User: , a hash of your own user id. Ask for what the screen shows.

  1. Video and stills come from POST /v1/media/urls, for a named person: header

fresh ones when a screen opens.

  1. Store exercise ids, never media URLs. Signed URLs expire after 15 minutes by default. Ask for

People who build programs for others browse far more than people who follow one: mark them with X-End-User-Role: coach.

When ExerciseBank is the right pick

GET /v1/exercises/:id/substitutes answers with ranked replacements and the reason for each.

  • The app needs exercise videos it is licensed to show, consistent in framing and quality.
  • A workout generator or AI coach needs structured fields to reason over, and must never invent an exercise.
  • The app must swap exercises for the gear someone has or a joint that hurts:
  • The product is bilingual (English and French).

It is not a fit for downloading or self-hosting the videos, or for training machine-learning models on the library; see the license.
