yadavrinky/gym-guru — reverse-engineered prompt

Build me a polished full stack fitness app called Gym Guru.

I want users to sign up, complete a fitness onboarding flow, then use a dark modern dashboard to track workouts, meals, calories, protein, progress, and recent activity. Add an AI camera trainer that uses the webcam to recognize common exercises, count reps, score form, and give live coaching feedback. It should let users log sets, including a simple gesture based confirmation if possible.

Also include food logging where someone can type normal text like “2 eggs and toast” and get estimated calories and macros, plus exercise logging from phrases like “30 minutes running”. Add two separate chat assistants, one for workout advice and one for nutrition advice, with saved chat history.

I also want analytics charts, profile editing, gym or program recommendations, and habit nudges if someone is likely to skip workouts. Use a Next.js frontend with a Python FastAPI backend, MongoDB, Firebase auth support, WebSockets for live features, and a sleek dark glassy UI. Look up current docs online if needed.
