Lucas Werthein, the COO and co-founder of Cactus, shares how he built a personalized AI wellness coach using ChatGPT to optimize his athletic performance while managing past injuries. After multiple surgeries on his knees, shoulder, and foot, Lucas created a system that synthesizes data from medical imaging, blood tests, wearable devices, and nutrition plans to provide personalized recommendations. His AI coach helps him balance competitive tennis, weightlifting, and running a company while maintaining his goal of “feeling 25 in a 40-year-old body.” Lucas demonstrates how this approach transforms siloed health information into actionable insights that protect joints, optimize recovery, and extend peak performance.
What you’ll learn:
- How to configure a ChatGPT with multiple data types, including MRIs, x-rays, blood tests, and wearable metrics, to create a comprehensive health profile
- A framework for setting clear performance boundaries that prioritize joint protection, energy optimization, and injury prevention
- Techniques for using AI to balance nutrition around special events like social dinners while maintaining performance goals
- How to use images and videos to get AI feedback on physical symptoms and injury recovery timelines
- A method for validating and contextualizing medical advice by having AI synthesize information from multiple health-care providers
- Why creating clear rules and anti-prompts helps AI deliver practical, evidence-based recommendations instead of trendy supplements or extreme protocols
