Turn your gym into a system: bookings + coaching + reporting.
You built a premium brand — but operations still run across booking tools, spreadsheets, and separate invoicing. One platform. Your whole gym.
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.

Stop running your gym on five tools
Bookings are operations. Coaching is delivery. They belong in one system — but nothing connected them end-to-end until now.
Marcus runs a boutique PT studio with 6 coaches — this is what changed when he unified everything:
- Bookings in Calendly, programming in Google Sheets, payments elsewhere — double admin and confused clients.
- Every coach programs classes differently; clients notice when the experience doesn't match the brand.
- No owner view across clients, coaches, and revenue without chasing the team for updates.
- Group class programming eats hours every week with no shared library or standard.
Comparison
Gainz Coach vs disconnected tools vs other software
Why boutique gyms and PT studios choose one platform over stitching Calendly, sheets, and invoicing together.
| Disconnected tools | Gainz Coach | Other software | |
|---|---|---|---|
| Bookings & scheduling | Calendly or similar for bookings, coaching elsewhere — clients bounce between tools. | Branded public booking page and booking agenda — sessions, classes, and memberships in one flow (Gym tier). | Booking add-on, not tied to coaching delivery or your brand. |
| Group class programming | Each coach builds classes their own way; programming takes hours with no shared foundation. | Group training program builder linked to class booking — standardize delivery without micromanaging coaches. | Class scheduling only — no structured program builder tied to sessions. |
| Team & permissions | No permission structure; standards live in someone's head or a private folder. | Team management, coach permissions, and shared exercise and program libraries across your roster. | Single-coach focus — weak or no multi-coach permissions. |
| Client-facing app | Clients get links, PDFs, and different apps depending on the coach. | One branded mobile app for daily training, nutrition, and booking — looks like your gym, not a generic tool. | Generic client app with limited branding. |
| Coaching delivery | Inconsistent delivery; owner can't see what's happening without being in the room. | 1:1 and group coaching with progression insight, meal plans, and check-ins — same quality bar for every coach. | Solid for 1:1 online coaching, weak for in-gym teams and classes. |
| Billing & access | Separate invoicing tool; membership access managed manually. | Automated billing with access tied to payment status — less chasing invoices, fewer admin gaps. | Billing without tight link to coaching periods or gym access. |
| Owner reporting | If you can't see retention, you can't fix it — spreadsheets updated when someone remembers. | Finance dashboard: MRR, churn, retention — owner-level visibility without asking coaches for numbers. | Coach-level stats, not gym-owner business metrics. |

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.”

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.
