I like this gym at Chase Field. I was there while the game was on and it was a good place to work out and watch the game on tv. Staff is friendly and really easy to talk to. Environment is clean. Bathrooms are up to date with towel service and steam room. Hours are pretty good if your an early bird or stay up late. Lots more for me to explore. No complaints yet. The parking lot was nearly empty during a game last time I went so I think the issues others have mentioned have been worked out. I love the parking pass for chase f... read more

YO. I could have sworn I threw a yelp review up when I said I did, guess it didn't show. I've worked at and worked out at numerous gyms.. and mountainside fitness is not only a great facility, but the staff and managers take care of all of us thoroughly. They work with what you can and can't do.. its overall an amazing environment to reach your goals in! (P.s. the manager James has helped me with my struggles financially like you would never believe!!)

Dear Mountainside Fitness Management, I am writing to formally file a complaint regarding a deeply upsetting experience I had at your Desert Ridge location on April 30, 2025, and to bring to your attention an unauthorized charge made to my account. For three consecutive days, I confirmed through your membership support line that my account was active. On the morning of April 30, I even received written confirmation from your team (attached) stating that I was indeed on the membership. Based on this clear assurance, I arriv... read more

There is literally never parking at this location. It's so frustrating when you're getting amped for a workout, and there's not a single parking spot.
