On a Sunday evening in ?, we sent the same short message to ? gyms:
For gyms with 1,000+ members
Sunday, 21:14. Someone wants to join your gym. Nobody answers.
By Monday, they've signed up somewhere else. We make sure every enquiry gets a friendly WhatsApp reply within two minutes, even on Sunday night.

Hi! Can I come and try a class this week?
Hi, sorry for the late reply! Of course. When suits you?
Thanks, but I've already joined another gym.
We tested it ourselves on real gyms.
“Hi! Can I come and try a class this week?”
Then we waited, and wrote down when each gym answered.
- Same evening?
- Monday?
- Tuesday?
- Never?
Nobody at those gyms is lazy. The desk is closed on Sunday night, Monday is busy, and the message gets buried.
But the person who asked doesn't wait. They message the next gym.
Here's the same Sunday with GymFlows.
Someone asks
Through your website form or on WhatsApp. Any day, any time.
They get an answer in under two minutes
A friendly WhatsApp in your gym's words, with a link to book a trial. If they go quiet, it follows up. If they say stop, it stops for good.
Your team takes over on Monday
Every conversation is waiting in one inbox. Nothing got lost over the weekend.
It connects to the member software you already use. Your team doesn't have to learn anything new.
Hi! Can I come and try a class this week?

Is this for you?
Yes, if
- Your gym has 1,000 members or more

Not for you, if
- You're not taking on new members
- You still do everything the old-school way, by hand on paper
- You can't change your own website or member software Some franchise gyms can't.
What happens on the call.
Twenty minutes with Anton. Free.
It's mostly questions. How do enquiries reach you today? Who answers them on a Sunday? What software do you run? By the end, we'll both know if we're a good fit.
If we are, the next step is the Sunday Night Report. In one week we test your gym the same way we tested the others, and show you with your own numbers where people slip away.
If we're not a fit, we'll tell you on the call.

Do we need new software?
No. We connect to the member software you already use. If yours can't connect, we'll tell you on the call.
Is a robot talking to our members?
The first reply is sent automatically, in words you've approved. Your team handles the conversation from there. If AI is ever switched on to chat with your members, it says it's an AI. You decide when, if ever.
Our members don't use WhatsApp.
Maybe. Let's check instead of guessing: the Sunday Night Report shows when and how your enquiries actually arrive.
What about GDPR?
Before we see any data, we sign a data-processing agreement with you. You get a written list of every company involved in handling your data.
What does it cost?
That depends on your gym and what you need. We'll talk about it openly on the call, with real numbers.
Who are you?
