Best Free Exercise Databases & Apps in 2026, Compared
By ExerciseLibrary Team · Comparisons · Published 2026-06-27
We ranked the best free exercise databases and workout apps for 2026 — reference libraries vs trackers, with a full feature matrix, pricing, and sources.
The fitness app space splits into two jobs: looking up how to do an exercise (reference libraries) and logging the sets you lifted (workout trackers). This guide ranks the best free options for each, as of June 2026, with a side-by-side feature matrix and sources you can verify.
Disclosure: ExerciseLibrary is our product. Every tool below is scored on the same public criteria, and we link to each source so you can check the data yourself.
The short answer
Reference libraries vs workout trackers
Reference libraries (ExerciseLibrary, MuscleWiki, ExRx.net, Bodybuilding.com) answer "how do I do this exercise and what does it work?" Workout trackers (Hevy, Jefit, Strong) answer "what did I lift today?" Trackers' exercise databases are smaller because they exist to attach to a logged set. Most lifters use one of each.
