COACHCOACHThe Smartest Coaching System for Strength & Hybrid Coaches.
Program faster, track smarter, and scale your coaching business — without adding admin overhead.
No hidden fees, no obligations
Eindelijk kan ik klanten coachen zoals ik zelf wil, zonder beperkingen opgelegd door gebrekkige software. Wekelijks programmeren bespaart me veel tijd door het handige design.
— Ben Serneels
The problem
The coaching tools did not match the quality of the coaching I provided
Most coaching businesses run on a mess of spreadsheets, chat apps, and manual billing. More clients > more chaos > lower coachingquality.
Programming was time-consuming
Hours spent rebuilding programs for each client.
Progress tracking was a mess
Client data scattered across five different apps with no single source of truth.
Check-ins were a pain
Check-ins buried deep in WhatsApp, emails and unread DMs.
Manual billing
Chasing invoices and managing payments instead of coaching clients.
From the founder
Why Gainz?
Gainz was born out of frustration; frustration that the coaching software available in the fitness industry is simply not good enough.
So inadequate, that across my 15+ years as a fitness coach, I never stopped relying on spreadsheets.
Not because spreadsheets are great, but because there simply was no software that did exactly what I and my clients needed.
Over the years I've tested almost every product on the international market, and every time I ran into the same problem. Software is built by developers, not by coaches. And you can tell.
Sure, there's software that does some things well. But 'good' isn't good enough — I need software that does EVERYTHING well. Not just nutrition, not just training, and not just admin and billing.
One system that handles EVERYTHING, without compromise.
Training, nutrition, recovery, progress tracking, and all your data should live in one system. One system that gives you the valuable insights you need to maximise your clients' progress.
That system is Gainz Coach — the all-in-one tool for fitness professionals. Whether you're a personal trainer, an online coach, or a gym owner: this is the tool for you.
I can say that with confidence because I built Gainz from the ground up myself. As a coach, for coaches. For my own clients, for your clients.
The bar is high: everything has to work fast and effortlessly, without headaches. I want to focus on coaching, without worrying about whether the admin is running correctly or whether payments are going through smoothly.
This is software for the professional who wants to deliver great coaching — without limitations, without hassle.
And that applies not just to the software, but to the entire development process. As a coach you stay closely involved in shaping the platform, with the opportunity to share feedback and ideas for new features at any time. Direct lines to me as the developer and genuine involvement — the way you'd expect from coaches working together.
No fluff, no nonsense — just direct contact with me, for the best possible results for your clients.
This is Gainz Coach: by coaches, for coaches.
And honestly? This is only the beginning.

What coaches say
“Ik gebruikte hiervoor Virtuagym. Gainz Coach geeft overzicht en het is gemakkelijk in gebruik. Het biedt eigenlijk alles wat je nodig hebt. Het combineert training, voeding en gedragscoaching in één platform, wat het erg geschikt maakt voor coaches die hun klanten op afstand begeleiden en overzicht willen houden over het volledige traject.”
