Abstract: The current digital health landscape is saturated with generic fitness applications that fail to address the unique physiological and lifestyle constraints of individual users. This project, "FitAI Professional," addresses this challenge by developing a full-stack web application that leverages Generative AI for hyper-personalized coaching. Built using a React (Vite + TypeScript) frontend and a Node.js (Express) backend, the system integrates the Google Gemini model to act as an intelligent, context-aware planning engine. Unlike traditional rule-based systems, FitAI Professional interprets complex user profiles—including biometrics, equipment availability, and injuries—to generate structured, scientifically sound regimens. Key innovations include strict JSON schema enforcement for AI outputs and multimodal food analysis for seamless nutrition logging.
