Mountainside Fitness, the largest locally owned chain of fitness centers in Arizona,  opened a 2-story, 13,000 SF Platinum Fitness Center inside Chase Field today.

The facility is the nation’s first fitness club to be placed inside of a professional sporting venue. A.R. Mays Construction was the general contractor and Saemisch-DiBella Architects provided the design work for $1.6M project.

The ground floor of the club is located along the main concourse level of Chase Field and includes a cycle studio with windows that look out onto the interior of the ballpark. Mountainside Fitness’ center also occupies a mezzanine level that features a group fitness room and cardio studio.

Open 363 days a year, the club offers a variety of other amenities, including personal training, a tanning room, a steam room, café, laundry service and a members-only parking lot for ease of access.

When not in use by the Arizona Diamondbacks, Mountainside Fitness members will also be permitted to utilize other areas of the stadium for participating in group classes and activities unique to the ballpark, such as a run up and down the stadium stairs.

“With the opening of our fitness center inside of Chase Field, we have not only acquired one of Arizona’s most unique pieces of real estate but we have also created a place to serve our growing urban membership base,” said Billy Malkovich, CEO of Mountainside Fitness.

“In addition, we recognize that many of our members across the Valley daily commute downtown for work as well and this provides the opportunity for them to conveniently workout before work, during lunch or after work. We have options to fit everyone’s schedules.”

Mountainside Fitness also plans to implement a dedicated shuttle service that will transport Mountainside members to and from their places of business downtown. The Chase Field Mountainside Fitness club expects to serve approximately 2,500 members.
