Avalon Fitcentre is on Sint Hubertusstraat in Nijmegen. It holds a 4.2 rating from 97 Google reviews.
The record is old: the newest written review dates from July 2019, so nobody has described this gym in seven years. Two of the four reviews are in Dutch, and my translations are marked below.
The Weekend Hours Are The Complaint
The only criticism on record, from a member in June 2019, four stars (translated from Dutch): "Fine gym, would just be nice if they were open until 10 on Saturday and Sunday too."
He's asking for weekend hours to match the weekdays. And the listing confirms exactly why he's asking.
Monday to Friday, 08:00 to 22:00. Saturday and Sunday, 09:00 to 17:00.
Fourteen hours a day on weekdays, eight at weekends, closing at 17:00. If your training week is built around long weekend sessions, that 17:00 Sunday close is the thing that will annoy you, and a member was already annoyed by it in 2019.
Whether it's changed since, I can't say. Those hours are on the listing now, but this record's other details are seven years stale, so I'd treat the schedule as a starting point and confirm.
The 08:00 Weekday Open
Worth flagging the other end too. Nothing before 08:00, any day.
For a gym in a university city, that rules out the before-work crowd entirely. If you train at 06:30, this isn't your gym, and no reviewer mentions any early access.
What Members Liked
Three reviews, and they're brief.
A member in March 2018: "A lot of machines and very helpful staff. Friendly atmosphere."
A member in July 2019 (translated from Dutch): "Good place to work out, good rate with good equipment available."
A member in March 2019: "It is so nice place I really like it."
"Good rate" is the only pricing signal anywhere, and it's an opinion rather than a figure. Machines, helpful staff, friendly atmosphere. That's the whole positive case, from 97 ratings.
What Nobody Says
For a gym with nearly a hundred ratings, this written record is remarkably empty.
Nobody mentions classes, a sauna, a pool, parking, changing rooms, or how busy it gets. Nobody names a trainer. Nobody says what a month costs. Nobody describes the free weights.
So the 4.2 is probably a fair reflection of a decent neighbourhood gym, and I can't tell you much more than that. If you want the current timetable and pricing, avalonfitcentre.nl is where they'd live, and the number is +31 24 663 5173.
Who It's Not For
Early risers, given the 08:00 open.
Anyone who trains long on Sundays, given the 17:00 close. One member has already made that complaint for you.
Anyone choosing on facilities, since this record doesn't describe any beyond "a lot of machines."
Sint Hubertusstraat 2, Nijmegen.
