Ava Fitness

1. Build a simple web app with user onboarding (age, fitness level, goals, available equipment) → stores in PostgreSQL 2. Create a workout library (100-150 video demonstrations + text descriptions of common exercises; shoot or license cheaply) and categorize by muscle group, equipment, duration 3. Implement a basic recommendation engine: rules-based first (if beginner + no equipment → bodyweight circuits) or simple vector matching; progress users weekly based on completion 4. Add progress tracking (reps, sets, weight, perceived difficulty) and let users log workouts; surface simple stats (workouts completed, streaks, calories burned estimates) 5. Launch with email/WhatsApp reminders, freemium model (3 free workouts/week), and paid tier for unlimited access + form feedback (video upload + AI form check via Gemini Vision or similar)
