Exercise Dataset Attribution

Product Hunt shoutouts focus primarily on products so I'd just like to use this thread to credit the authors of and contributors to the public domain dataset this project is based on.

The original dataset is courtesy of OllieJennings which can be found here on Github, it was restructured by yuhonas in this fork which I made use of.

LiftEngine - Workout plans tuned to your goals, kit and schedule

You describe your goals, equipment and training days. A constraint-based solver rules out anything infeasible: recovery windows, equipment you don't own, time limits. A genetic algorithm evaluates the rest against ten training-quality criteria (progressive overload, muscle balance, compound-to-isolation ratio and others) and evolves them toward the best fit. Exercises in each session are ordered by modality so warm-up, main work and cool-down fall in place. Free, no sign-up, six languages.
