NeuralBuilt · Case study

An AI coach that knows your genome and your data.

Built for one athlete chasing a 3:30 marathon, a 21 mph sprint, and 400/350/500 lifts at the same time. It reads your sleep, your readiness, your genetics, and every workout you have ever logged, then tells you the exact next move.

Why we built it

Goals that do not coexist peacefully.

Run a 3:30 marathon. Sprint at 21 mph. Hit 400/350/500 on the big three. Hold single-digit body fat. Do all of it as a founder who trains five times a week and builds companies in the mornings. The standard advice for that ambition is: pick one. Training for maximum strength and endurance at once creates a measured interference effect, and most coaches tell you to accept the drift.

The bet was that the interference could be beaten, not with more willpower, but with a system no individual coach or generic app has ever had: one that continuously learns the literature, knows your exact genetic risk factors, holds every workout you have ever logged, reads last night's sleep, and sequences your training peaks on a single calendar.

The problem

Generic apps do not know you.

They show you macros and log your reps. They do not know that you carry COL5A1 TC, an altered collagen gene that makes your tendons vulnerable, which is exactly why the collagen protocol is non-optional after an ankle fracture. They do not know that your ACTN3 XX genotype actually gives you a recovery edge between sets. They do not know that LMNT cramps you, even though every sports-nutrition app would recommend it.

And even if you log everything, sleep, readiness, body composition, workouts, supplements, meals, you are still doing the synthesis yourself. Turning a 131-table picture of your own body into a coherent, science-backed, injury-aware plan is not something a person does daily, and not something a single app does at all.

The breakthrough

A coach that knows your whole picture.

Most fitness apps bolt a generic chatbot onto a database. NeuralFit's coach holds the full context of your body and history at once: every workout you have logged, last night's sleep and readiness, your genetics, your supplements, and your goals. It does the synthesis a person cannot do daily, and it never forgets what came before.

On top of that runs a daily literature review personalized to your DNA, proactive push notifications, an offline-first logger that never loses a gym entry, and multi-image meal capture. Your data stays yours, private and fully owned, never mined on someone else's servers.

What you get

A year in the making, and finally here.

The coach does the synthesis you cannot do daily: it closes your macros around a hard dual-load day, times your carbs for overnight glycogen repletion, enforces your collagen and magnesium protocol on schedule, and explains the why every time. It knows your injury history, your genetics, and your real logged data, so the guidance is yours, not a generic prescription.
