  1. Building The IT Guy Was There First Before the gyms, before CrossFit, I was the IT guy. The AI side was never a new chapter. It was the old one, coming back.
  2. Training Any Program Works for a Beginner A beginner improves on almost anything. That says more about the body than about the coach.
  3. Building The Efficient Company Is Not the One With the Fewest People What frontier AI users keep finding after they automate: more human work, not less. And why the efficient company is the one where agents do the repeatable layer.
  4. Building I Build Agents Around Real Life A few concrete examples of how I use AI agents across the house, the gym, the business, and the strange corners of my life.
  5. Training The One-Tool Coach A running coach defaults to running. A powerlifter defaults to powerlifting. The best coaches don't default to anything.
  6. Training Coaching Should Have a Reason Complicated exercises can look creative, but good coaching starts with a clear reason.
  7. Training Life Is Not Low Impact Low-impact training has its place, but a body protected from all impact becomes less prepared for real life.
  8. Operating Do Not Let AI Make Your Business Look Cheap AI can remove friction from a business, but the public face still needs human taste.
  9. Operating The AI Stack Is Not the Point I am a business owner first. That changes how I look at AI.
  10. Operating Hard Decisions Keep the Room Alive Ten years of running Subtero taught me that community survives when someone protects the standard, even when the conversation is hard.
  11. Training Coaching Requires Discretion A note to myself on teaching more coaches without confusing enthusiasm for readiness.
  12. Operating The Advantage Is Not AI. It Is Using AI. A field note on my actual AI stack, the agents I use, and how AI changed the distance between idea and product.
  13. Training Coaching Is Pattern Recognition Good coaching is not about having better cues. It is about seeing the pattern in front of you before you speak.
  14. Operating Passion Is Not Enough to Run a Gym After ten years of running Subtero, I learned that passion may start a gym, but it does not sustain one.
  15. Operating Small Automations I Actually Want in a Gym Business Most gym owners do not need a grand AI strategy. They need small automations that remove weekly friction.
  16. Building What Running a CrossFit Box Teaches About Systems A gym looks like energy from the outside. From the inside, it survives on systems people can actually follow.
