4gym.net

Gym management software for every kind of fitness facility

4gym.net works for any gym, sports club or studio — from neighbourhood gyms and small chains to CrossFit boxes, yoga studios, martial-arts halls and pools. Set up your memberships and class timetable in minutes and start taking sign-ups online.

Classic fitness gyms

A strength-and-cardio floor with monthly, annual or 10-entry memberships and a configurable joining fee.
Every member has a profile with their attendance history, active membership and next renewal date.
See in real time how many members are on the floor and how busy peak hours get.
Renewal reminders go out automatically before a membership lapses.

Sports clubs

A club with several sections and training groups, with a timetable per pitch, per hall and per coach.
Each group has a participant cap and attendance is marked at every session.
Monthly dues are collected on a recurring schedule and arrears surface immediately in the office list.
Reports show attendance per group and retention from one season to the next.

Yoga and pilates studios

A studio with small classes where every spot counts: you set the room capacity and bookings close automatically once every mat is taken.
Remaining members join the waiting list and are notified the moment a spot frees up.
Sell packs of 5, 10 or 20 sessions and track how many each member has left.
A timed cancellation policy protects spots from no-show bookings.

CrossFit and functional training boxes

A CrossFit box with WODs on fixed hours and a dedicated coach per class.
Booking opens a configurable number of hours in advance and capacity matches the number of available stations.
Track each member's progress on lifts and benchmarks, and at month end review occupancy per time slot and per coach.

24/7 unattended gyms

A gym open around the clock with no permanent front desk: access runs on a card, wristband or QR code, and the reader validates the membership in real time before releasing the turnstile.
Expired or frozen memberships are rejected automatically at the door, with the reason visible in the log.
Cap the maximum simultaneous occupancy and see who is inside at any moment.

Personal training studios

A studio built around 1-on-1 sessions, with a separate calendar per trainer and session packs bought upfront.
A session is deducted from the pack only once it is marked as delivered.
Trainers see their own schedule and accrued commission, while you see how many unused sessions are still in the system and what they are worth.

Martial arts halls

A hall with groups by level and by age, from kids to advanced, with a timetable per mat and per instructor.
Training attendance is the basis for belt gradings.
Manage monthly fees, grading fees and the equipment sold at the desk.
For minors you keep the guardian's consent and contact details on file.

Pools and aquatic centres

A pool with bookable lanes and swimming courses by group, where capacity is set per lane rather than per room.
Memberships can be restricted to time bands so open swimming stays separate from course groups.
Locker-room access uses the same wristband as the turnstile, and attendance at every course stays in the member's history.

Frequently asked questions

Quick answers to the most common questions about the 4gym.net platform for gyms, sports clubs and fitness studios.

How long does it take to set up my gym on 4gym.net?

You can start the same day: create the gym account, define your membership types, the class timetable and your trainers, then import your member list from an Excel or CSV file. Initial setup takes between 30 minutes and a few hours, depending on how many membership types and classes you run.

What does the 4gym.net platform include?

4gym.net brings memberships and your member base, class scheduling with limited seats, trainer calendars and personal training sessions, door access control and recurring-revenue reporting together in one account — plus a connection to the 4b2b ecosystem for invoices and notifications.

How does door access control work?

Each member gets a card, a wristband or a QR code in the app. At the door the reader validates the membership in real time: if it is active the turnstile opens and attendance is logged automatically; if it has expired or been frozen, access is blocked and the front desk sees the reason immediately.

Can members book classes themselves?

Yes. You enable 24/7 online booking and members pick the class and time slot from the timetable. Seats are capped per class, and when a class fills up members join the waiting list automatically and get notified as soon as a seat frees up.

Can I track renewals and expiring memberships?

Yes. At any moment you can see how many memberships expire in the next 7, 14 or 30 days, who has not shown up for more than two weeks, and what your monthly renewal rate is. Reminders go out automatically by SMS or email before a membership lapses.

Do I need technical skills?

No. Everything is managed visually from the gym panel, with no code and no installation. If you can use a smartphone, you can use 4gym.net.

What it is

What gym management software is

Gym management software is a single platform that brings together member subscriptions, group-class bookings, personal-training sessions and door access control. 4gym.net is the all-in-one platform in the 4b2b ecosystem: recurring memberships with automatic renewal, a class timetable with capped spots and a waiting list, a calendar per trainer, card or QR access validated in real time, attendance tracking and recurring-revenue reports — no paper membership register and no juggling separate apps.

What you can manage with 4gym.net

Memberships: recurring, renewals, freezes
Group classes with capped spots and a waiting list
Trainers, personal-training sessions and commissions
Access control: turnstile, card or QR code
Member attendance and renewal alerts
Payments, invoicing and recurring-revenue reports

Pros

Get started the same day — no technical setup needed
Members book classes online 24/7, with no calls to the front desk
Membership, attendance and history — all in one place
Renewals are collected automatically, with no trip to the desk
The turnstile validates the membership in real time, even with no staff on site
Connected to invoicing (4invoices) and notifications (4notify)

Cons

We are transparent — here is where 4gym.net is not yet the best fit:

Chains with dozens of locations and franchises need a dedicated setup
It does not replace a member-facing workout app with plans and exercises
An online supplement store with thousands of SKUs integrates separately
Turnstiles and physical readers are bought separately, from a hardware supplier

How it works (3 steps)

Create your gym account

Add trainers and the class timetable

Set up trainer profiles, group classes, the capacity of each room and prices — everything managed visually, no code required.

Turn on online sign-up and access

Members book their own spot in a class, receive automatic SMS reminders, and at the door their card or QR code validates the membership.
