AI-powered training and nutrition planning. Personalized routines, progress tracking and adaptive recommendations. From idea to functional product with real users.
The problem
Creating personalized training routines and nutrition plans requires specialized knowledge and time. Most people can't afford a personal trainer or nutritionist, and generic apps offer static plans that don't adapt to the user's real progress.
The solution
The system takes each person's goals, level and preferences and generates the routine and meal plan with OpenAI. Then it keeps correcting them against what the person actually logs: metrics, workout history, and which parts they stick to and which they don't.
