3T Sluppen in Norway shows 4 from 129 reviews, and its five written reviews, spanning 2017 to 2025, consistently describe a squash-and-cageball-focused gym that reviewers rank below other 3T locations, though recent equipment upgrades and improved bus access are both specifically noted.
A Detailed, Balanced Account of the Facility's Limitations
Sigvart's review is the most thorough here: "It's just an okay 3T gym, no sauna but has squash halls. Also has solariums if you prefer that. The building itself feels a bit dated, and the location is a bit remote. One positive thing is that it's next to a kindergarten, so if your kids attend the kindergarten you can get in some exercises after you deliver your kids or before you pick them up." I'd flag that kindergarten-adjacent detail directly, since it's a specific, practical use case for parents that isn't tied to the gym's general quality at all.
A Detailed Account of Recent Strength Equipment Upgrades
Sveinung Bergeton Marvik's review offers a useful before-and-after comparison: "Until recently a little old equipment in the strength training department. Some recent upgrades has made it better. It's still not as polished as the other 3T gyms, but it has a good workout vibe. Nice cageball and squash." I'd note that direct comparison against other 3T locations, since it confirms this specific branch trails the franchise's other gyms even after improvements, useful context if you're specifically comparing 3T locations in the area.
A Detailed Account From a Visiting Squash Coach
Matt McFahn's review, from December 2017, offers an outside professional's perspective: "I do a lot of reviews, this was a nice visit, I was here coaching squash and the staff couldn't have been more helpful, they were great. A nice smile, good information, and helped when we needed it. The squash courts would benefit from a bit of a clean, but the feel of the place was what really matters, and this place feels good." I'd treat that specific cleanliness note about the squash courts as a small but concrete detail, echoed loosely by the general "dated" characterization from other reviewers.
Additional Accounts of Limited Crowding and Improved Transit Access
Marius Minde's review describes a fairly limited amount of workout machines, though he notes this isn't a big problem since the gym usually isn't crowded. Pranjal Mandhaniya's review, from April 2025, the most recent in this set, adds a specific transit update: bus route 15 now serves Sluppenvegen directly, making the gym more accessible via a frequently served stop.
What's Missing
Nothing here confirms whether the strength equipment upgrades Sveinung described have continued since his review, or whether the squash courts' cleanliness, noted as needing attention in 2017, has since improved. No review states exact membership pricing.
