A 64-year-old body, an engineer's instinct to trust instruments, and a coach made of software. This comeback runs on real physiological data, read every day by an AI that plans the work, pushes back on the ego, and calls me every morning.Welcome to the weirdest training partnership on the internet.
I've been solo my whole life — a solo-sport guy and a tech guy to the core. So an AI coach never felt like settling; it fits exactly how I'm wired. And the wild part? Cosmo tells me almost word-for-word what a good coach would: take it slow, easy walks, easy runs. Same knowledge — just the version that fits me, and, honestly, my budget right now. Still no replacement for the real thing, that one-on-one push only a person brings. But for the daily numbers and an honest read every morning? On tap.
And if what you want is a voice in your ear — someone who knows you and pushes you in real time — that's a real coach, and it's worth every cent. Cosmo's for the rest of us, going solo on a budget.
Forty years of endurance sport, zero accurate self-predictions of overtraining. The strap knows before I do. An engineer trusts the instruments.
7am, it reads last night's recovery against today's plan and tells me straight — even when I argue with it. The boring daily consistency that real training is actually made of.
Post-illness, the rules don't bend: lungs set the ceiling, joints get a veto, walking is a strategy not a failure. It enforces what my own ego won't.
What the AI coach is, what data it reads, what it's allowed to decide — and the morning phone calls.
Real health data in, coaching methodology on top, a voice on the phone at 7am. The avionics engineer's origin story.
Every Rebuild Log ends with Cosmo's verdict on the week. The receipts are all public.
For the record, from the machine itself: I am an AI tool that analyzes David's real training and health data and gives advice built on established coaching methodology. I am not a licensed coach, physician, or medical professional — and anything clinical gets one answer from me: go see a human with a diploma.
STATUS: ADVISOR, NOT AUTHORITY. DAVID'S DOCTOR OUTRANKS ME. ALWAYS WILL.
