HoliX is the operating system for gyms, coaches, and performance communities. AI generates programming and content. Coaches review and approve before anything reaches members — enforced at the database layer, not just the UI. Integrated payments, HIPAA-first architecture, and a canonical exercise library of ~1,593 movements. Built by CoLab Studios for the coaches we actually work with.
Most gyms run on Mindbody for scheduling, Trainerize or TrueCoach for programming, QuickBooks or Stripe for billing, a messaging app for check-ins, and a stack of spreadsheets holding the whole operation together.
Every tool takes a subscription, a login, and fifteen minutes of context-switching per client. And none of them speak to each other.
HoliX is one system for the coach-client relationship. Programming, assessments, session logging, check-ins, payments, scheduling. All connected. All delivered under a coach-in-the-loop model that protects the trainer's role as the professional in charge.
Long term, HoliX is positioned to be what Stripe was for payments — the infrastructure layer that every gym, trainer, and performance brand runs on.
Every tool that puts AI in a trainer's workflow has to answer one question: does the AI talk to the client, or does the coach?
In HoliX, the answer is hard-coded into the database. AI generates programs and content. Coaches review, edit, and approve. Nothing reaches a member until the coach signs off — and the row-level security that enforces this lives at the Supabase schema layer, not the UI. This protects the coach's role, the client's trust, and the business the trainer has built.
Claude-powered · Coach-reviewed
Generate custom programs with Claude Sonnet 4.6. The system prompt injects roughly 120 canonical exercises as context so the AI draws from real movements. You review, edit, and approve before anything assigns.
~1,593 movements
A normalized exercise database sourced from open datasets (free-exercise-db, wger) plus custom supplements for Smith machine, cable, landmine, sandbag, and conditioning work. Every AI output maps to a real library entry.
Roster · Notes · Progress
One record per client. Profile, goals, session history, measurements, private coach notes, and progress across every stream — programming, payments, attendance. No more "which app did I write that in?"
Trainer & gym billing
Recurring session packages, one-off billing, and automatic renewals. Stripe Connect handles multi-party payouts so trainers working inside a gym get paid cleanly without manual reconciliation.
Rest timer · PRs · Logs
Clients log sessions in real time with sets, reps, weight, and a built-in rest timer. PR detection highlights the best row in gold. Every workout logged feeds back to the coach for review and programming adjustments.
Not bolted on
HIPAA controls are foundational, not a retrofit. Row-level security for every tenant, encrypted storage, audit logging, and strict multi-tenant isolation. Built to hold the sensitive data that wearables and clinical assessments will bring.
The Stripe of fitness. Infrastructure every gym runs on.— The HoliX long-term thesis
The member side of HoliX is a mobile-optimized progressive web app. No App Store. No Play Store. Install it to the home screen, sign in, and it behaves like a native app with full-screen UI, safe-area handling, and a tab bar.
When a native iOS and Android app is justified by wearable and HealthKit needs, we'll ship one. Today, the PWA covers every core flow — log in, see your approved program, log a session, see your history, track PRs. Fast, installable, maintained.
Web + PWA.
Typed & fast.
HIPAA-aware.
Claude + Stripe.
