Gyms with Group Classes in Colorado

122 of the 396 gyms we track in Colorado have group classes. Google's amenities list might flag a gym as having "group classes" without saying which ones run, how often, or whether non-members can even drop in — a gap that's invisible until you show up for a spin class that doesn't exist. Every gym on this page has its class schedule confirmed from the gym's own site or booking app, not a generic amenity checkbox. Full listings for every city are on the Colorado page.
