AI-Powered Personal Fitness Coach: A Proof of Concept

For a startup specializing in fitness technology, I developed an AI-powered personal fitness coach. This system leverages advanced language technologies, including GPT-4 and Command R+, to generate personalized and adaptive training plans tailored to individual user needs, setting it apart from generic, one-size-fits-all fitness solutions.


The project addressed the significant challenge posed by traditional fitness plans, which often fail to meet unique user requirements such as physical limitations, personal objectives, and equipment availability. The goal was to develop a solution that offers customized guidance, enhancing user engagement and efficacy of fitness routines.


Working in a dynamic startup environment, I contributed to this project by:

  • Efficient Workflow Management: Designing a workflow graph that efficiently captures necessary user data before plan creation, ensuring all critical information is considered.
  • Stateful, Multi-Actor Interaction: Using LangGraph, I developed a system capable of managing interactions with multiple users, maintaining stateful context over the course of user engagements.
  • Flexible System Architecture: Employing LangChain to provide an abstraction layer for integrating multiple large language models, I ensured the system’s adaptability for future technological enhancements.
  • Adherence to Fitness Best Practices: I structured the AI to adhere to established fitness best practices, thereby ensuring the reliability and effectiveness of the training plans generated.


This project has successfully demonstrated the potential for AI to revolutionize personal fitness training:

  • Personalization at Scale: The system’s capability to tailor fitness plans based on individual user profiles showcases a significant advance over conventional fitness apps.
  • Future-Ready Design: The architecture supports easy updates and integrations, such as incorporating new AI models and expanding functionalities like biometric feedback.
  • Expertise in Action: The project highlights my expertise in AI deployment, user experience design, and strategic technological implementation in a fast-paced startup setting.
