Gym Booking System: Build Class and PT Booking with AI

A gym booking system has to match each class to its room and kit, fill no-show spots from a waitlist and keep personal training in the right trainer's diary. Describe your timetable and rules to Mythex and it builds the booking app with member logins, an admin view and a real database, then publishes it to a link members can save.

Who it's for

Gyms and studios that run classes in a separate booking tool from their memberships, or manage spin and HIIT spots on a sheet at the desk, and personal trainers who keep their own diaries. It suits a single site with a few classes a day and a busy club with a full timetable.

What you can build

Spin capped at the number of bikes, lifting classes at the number of racks
A waitlist that moves the next member in when someone cancels
Late cancellation and no-show rules that differ by membership tier
Personal training booked into each trainer's available hours
Class bookings limited to tiers that include classes
A desk view of today's classes with check-in

What a gym booking system has to get right

Caps must match reality: twenty bikes means twenty places, not 'about twenty'. Cancellations need a window, perhaps two hours, after which the spot counts as used, otherwise popular classes fill with people who never turn up. The waitlist should promote automatically and tell the member, not wait for the desk to notice. And booking rights should follow the membership tier, so off-peak members only see off-peak classes.

Personal training in the same system

Trainers set the hours they are available, members book sessions against a PT pack, and the pack counts down with each session. Trainers see their own diary on their phone, and the desk can see everyone's, which ends the clash between a trainer's notebook and the class timetable.

Mistakes to avoid

Do not open bookings weeks ahead for small classes; regulars will block them out. A window of seven days is common. Do not let no-shows pass without any record, since a friendly note after the third one usually fixes it. And do not run a second booking tool for PT; it guarantees double bookings.

What to set up first

Enter your weekly timetable with caps, set the cancellation window and how far ahead members can book, and invite a few regulars to test it for a week. Then add the waitlist, PT diaries and tier rules. Attendance by slot can go on a dashboard once a month of bookings is in.

A prompt to start from

Build a booking system for my gym. Classes run from a weekly timetable with caps (spin 20, HIIT 16, yoga 25), members book up to 7 days ahead, cancellations within 2 hours count as late, and a waitlist promotes the next member automatically and emails them. Trainers set availability and members book PT sessions that count down from their pack. Give the front desk a check-in list for today.

Questions

Can members book classes from their phones?

Yes, in a phone browser with their own login. With Pro, Mythex can also turn the timetable into Android and iPhone apps that open it.

Does the waitlist work automatically?

Yes. When a member cancels, the next person moves in, and they can be emailed if you connect an email service.

Can only certain tiers book classes?

Yes. Describe which tiers include which classes or hours, and members only see what their tier allows.

Can I charge for drop-in classes?

Yes. Link a card processor in the gym's name and members can pay for a single drop-in or a class pack.

Is it free to try?

Yes. Class booking can be built and published on Free, no card required. Pro is $25 a month for a custom domain and more credits.
