Club Fitness’s spacious facilities fill with the low rumble of cardio machines and the clanging of tens of thousands of pounds of free weights and strength-training equipment. Youngsters scamper through the Kid Zone or children's nursery while their parents pump iron or shoot hoops on the basketball court. The gym’s trainers lead one-on-one sessions as well as group fitness classes. The soft squeak of feet against floors drifts from yoga sessions, and popular Les Mills classes include BodyPump, which combines high-energy music and repetitive moves like somebody repeatedly pushing the wrong way on a dance-club door. The purr of blenders drifts from the juice bar, where patrons refuel and chat after workouts.
