Introducing AI form feedback and AI-powered training coach.
Introducing AI form feedback and AI-powered training coach. Flex AI is the world’s first AI personal trainer. The new update (Flex 3.0) introduces real-time AI Form Feedback and Lex—an AI persona that adapts your workout plan, analyzes your lifts, corrects your form instantly, and answers questions about training, recovery, and nutrition.
This journey started seven years ago with a simple frustration: why are gym-goers still guessing their form? Back then I was tracking workouts in my Notes app, checking YouTube mid set, and wondering if I was doing any of it right. That spark turned into a seven-year grind, countless failed prototypes, one AI patent, and a team that refused to quit.
