Our mission
Make gym training accessible to everyone. WorkoutGen is built on Jeremy Tellier's expertise as a state-certified coach: a proprietary AI coaching system that structures your programs with periodization, progressive overload and methods adapted to your level. It then learns from your feedback session after session, and from thousands of athletes, to refine your program in real time, like a coach by your side. Our goal: the most personalized training possible.
4 goals, over 350 HD videos filmed by our team, a full-screen vertical player with integrated set tracking, recent progress views, complete scheduling management, 9 languages, and 1-click installation. The app is free to use, and WorkoutGen Max adds AI Coach guidance, load suggestions and advanced analytics. Behind every program is the expertise of a real human coach. Designed and developed in France.
