AI-APEX: Personalized Fitness, Nutrition & Coaching Powered By Generative AI

Metaviz AI proudly partnered on the development of AI-APEX, a fully AI-powered fitness, nutrition and hybrid coaching platform that creates personalized workout plans, custom meal plans, and progress-based recommendations using Vision AI + Generative AI. From photo-based body comparison to AI-generated workout demo videos, this app brings true personal coaching into one seamless experience. AI-APEX proves how AI automation can reshape the future of fitness apps with smarter personalization, better UX, and adaptive planning. This project included building a complete AI engine that understands user data, nutritional requirements, equipment availability, and physique goals, and then adapts weekly based on real user progress.

Challenges: Personalization Is Hard Without Real AI

Most fitness apps either repeat generic content or use static templates for plans. That approach can’t scale. Users want real personalization, accurate nutrition targets, training progression logic, visual change comparison, and coaching that evolves with time. Standard solutions lacked a unified platform that blends Vision AI + calorie logic + exercise selection into one flow. It became obvious that a new architecture was required, something adaptive, predictive, and visually driven.

Solution: A Next-Gen Coaching App With Adaptive Progress Intelligence

Metaviz AI developed AI-APEX as one unified coaching system with:

  • Personalized workout programming via GPT + custom plan engine
  • Vision AI photo comparison (past vs current vs ideal body)
  • AI-generated video demo clips tailored to experience level
  • Macro-based meal planning with recipe generation
  • Progress analytics with auto-recommendations
