It all started with a simple idea: to be the friendliest gym in town. To know our Members by name. To offer free towel service—even if that meant doing laundry until 2 a.m. That idea became Mountainside Fitness.
Today, with 25 locations (and growing) across Arizona, Mountainside Fitness is proud to be a leading fitness destination in the Phoenix area and beyond. We’re committed to delivering exceptional value through high-quality group fitness classes at every club, engaging childcare you can trust, state-of-the-art equipment, spotless facilities, and yes, always free towels.
