JavaScript helpers, TypeScript declarations, or direct JSON
Import the small dependency-free runtime when you want path helpers, or read the dataset directly when your build already owns the data layer. Image URLs returned by the CDN helper are pinned to the installed package version.
import repdb from '@repdb/exercises';
const exercise = repdb.getExercise('arnold-press');
console.log(exercise.name_en);
console.log(repdb.getImagePath(exercise, 'peak'));
console.log(repdb.getCdnUrl(exercise, 'peak'));const dataset = require(
'@repdb/exercises/exercises.json'
);
console.log(dataset.exercises.length); // 701Package contents
Exercise records and images ship together
Each record contains muscles, equipment, difficulty, goals, tags, MET values, localized instructions, and its available image poses.

FAQ
Using the RepDB npm package
Does the npm exercise package call an API?
No. The JSON, TypeScript declarations, and WebP images are installed with the package. There is no account, API key, runtime request, rate limit, or hosted-service dependency.
Can I use @repdb/exercises in a commercial fitness app?
Yes, inside personal and commercial applications with visible RepDB attribution. Republishing the package as another dataset or API is not allowed. Review the included LICENSE.md before shipping.
What is the difference between the npm package and the paid RepDB bundle?
The npm package contains the 701-exercise public catalog with flat 512px images. Paid RepDB plans include the same exercise records with 1024px assets, additional visual formats, and a commercial license without attribution. Standard also adds transparent backgrounds, animations, SQLite, and more developer formats.
Does the package support TypeScript?
Yes. The package includes declarations for the dataset records and its dependency-free helpers. The same exercise data can also be imported directly from exercises.json.
How does the package compare with ExerciseDB and other exercise APIs?
The package is local data: no endpoint, key or monthly quota. Hosted options such as ExerciseDB, WorkoutX, AscendAPI, API Ninjas, MuscleWiki and wger trade that for remote search and media delivery, each with its own quotas and license terms.
