A boutique gym on Joo Chiat Road that sells gym access without a long contract. Visitors pay per visit, buy several visits together, or take a monthly plan that costs less per visit. Everything is booked through the FiiTBOXX app, including gym access, one-to-one coaching and classes. The gym runs HIIT classes and has equipment for strength, cardio and functional training, with certified coaches for personal training. The website says the business opened about two and a half years ago. A newer space, FOXX Studio, has just opened for open gym sessions and personal training rentals. As at 2026, a 90-minute private studio rental was listed at $160, and a Rox training class at $28.
