About
The coaching platform we wished existed.
KBX started as a training tool for kettlebell, mace and Hyrox athletes — mirrored coaching, cadence pacing and honest AI feedback. It became the platform our coaches actually wanted to run their businesses on.
Today, KBX is an all-in-one coaching platform: workouts, nutrition with photo macros, habits, messaging with voice notes, bookings, video calls, Stripe payments, community channels and a visual automation builder. Athletes get a polished mobile PWA. Coaches get a hub that replaces Trainerize, Calendly, Stripe and a spreadsheet — in one app.
We're independent, UK-built and shaped by lifters under the bell. No gimmicks, no influencer noise — just the work, organised properly.
How we build
Mobile-first, always
Coaches run their business from their phone. Athletes train with their phone in front of them. Every screen is designed phone-first, desktop second.
One platform, not five
Workouts, nutrition, habits, messaging, bookings, payments and community in one app. No Zapier glue, no spreadsheet exports.
Honest by default
AI Honesty Score on every set keeps athletes accountable. Public methodology, transparent pricing in GBP, no dark patterns.
Built in the UK
Founded by competitive lifters. Engineered with UK-based support and GDPR-first data practices. Globally available.
