Colosseum Gym is in Kylemore Park South, Dublin 10. It holds a 4.7 rating from 263 Google reviews, and the record is current, with reviews through June 2026.
It's a serious lifting gym, the prices are published by a member, and there's one safety issue you should know about.
The Prices, From A Member
A member in July 2024 does what almost nobody does and names the figures: "Day passes are 10 euros and week passes are 15 euros."
Ten euros a day, fifteen for a week. So a week costs barely more than a day and a half.
If you're visiting Dublin, that's the whole calculation done for you. A member in June 2026 confirms the use case: "Really recommend going if you are in Dublin for a few nights and looking for a place to train."
The figures are two years old, so expect some drift, but the shape of the offer is clear.
Children On The Gym Floor
A member in April 2026, four stars, raises the one genuine concern here: "Nice gym amazing staff. However there are children running around the gym while we are lifting heavy weights with possibility of causing an accident harming the child and ourselves. This already happened 3 times. Gym is not a place for children."
Three times. That's the part that lifts this above a grumble.
A child wandering between someone's feet under a loaded bar is a real hazard, to the child most of all. This member still gave four stars, which tells you they like the place and are raising a safety point rather than attacking it.
I can't tell you whether it's been addressed since April 2026, or whether the gym has a stated policy on under-18s. If you train heavy and this would bother you, or if you're a parent wondering whether to bring a child along, that's the question for the desk.
What Kind Of Gym It Is
A member in July 2024 sets expectations precisely: "A great hardcore gym and the best in Dublin in my opinion. Most other gyms are chains that are overcrowded and lack proper machines and dumbbells. Colosseum has all that you need for a good training session: plethora of machines and a large inventory of dumbbells (going up to 150lbs). Don't expect a fancy gym if you come to Colosseum. If you're looking for a gym meant for training, this is it."
Dumbbells to 150 pounds. That's a specific, verifiable claim and it's the sort of detail that decides things: plenty of commercial gyms stop at 40 or 50 kilos.
"Don't expect a fancy gym" is the honest bit. No pool, no sauna, no spa mentioned by anyone.
A member in June 2026: "Great bit of equipment and stuff that isn't always that common in most gyms."
A member in April 2024, returning after two years out: "Very nice well equipped gym, lovely staff, there was classes going on, boxing facilities and loads of heads training who are in great shape (which says a lot about a gym)."
Boxing facilities and classes exist. Nobody says what the classes are or when.
Who It's Not For
If you want a polished chain experience, a member has told you outright not to expect one.
If you're a nervous beginner, "hardcore gym" is the members' own word, though several also describe the staff and the atmosphere warmly.
And if you were planning to bring a child, one member has made the case against it.
