How to book a class or session at your fitness center

Book a group class, an open session or your own time slot with a trainer from the Fitnexa website or app — and what to do when booking is switched off.

For membersWebMobile appUpdated 25 Sept 2026

Your fitness center decides how bookings work. Some publish fixed class times, some let you pick any time a trainer is free, and some do both. Fitnexa shows you whichever your center has switched on.

Step by step

  1. Open your center

    Sign in, click My Centers in the left-hand menu, then click Enter center → on the center you want to book at.

    In the Member menu, select My Centers.

  3. Pick a class, or pick your own time

    To join a class or open session: scroll to Open & group sessions, filter by Date or Service if you like, and click Book on the one you want. If it shows Full, click Join waitlist and you'll get the seat automatically if someone cancels.

    To choose your own time (centers that allow it): in Pick your time, choose the Date, Start time and Duration, then click Book Session.

If something goes wrong

I don't see Book a Session in the menu
Your center has turned off booking in the app. Message them from Messages or ask at the front desk — sessions they book for you still appear on this page, marked Booked for you.
Pick a date and time.
Choose both a date and a start time before clicking Book Session.
No open slots right now
Every published slot is taken or outside the booking window. Try another date, choose your own time if your center allows it, or join a waitlist.

Common questions

Can I book at more than one center?

Yes. Each center you belong to has its own Book a Session page. Open the center from My Centers first.

Why can't I cancel a session marked Booked for you?

Your center booked it on your behalf, so only they can change it. Ask the front desk or your trainer.
