Mountainside Fitness Chase Field

This was my first time visiting this gym and I had a great experience. I arrived around 7-8 AM and only had to wait about 1 minute before someone came to help me( and she had clearly stepped away to do some maintenance cleaning rather than for personal reasons). She was very attentive and friendly, which I really appreciated. Parking was easy and having plenty of spaces nearby is a huge plus. The equipment is well maintained and there’s a good variety of machines. It also wasn’t crowded in the morning, and the overall atmosphere felt friendly and welcoming. The locker room and showers were very clean and smelled nice. There are plenty of towels available, along with a vanity area, hair dryers, and a steam room. Just note that you need to bring your own shower products. An extra shout-out to the staff: on my very first day I somehow managed to lose my AirPods Pro. The staff found them, carefully placed them in a clean sealed bag, and it was super easy for me to retrieve them. I was honestly so relieved. Overall I’m extremely satisfied with my experience here and really appreciate how helpful and professional the staff were.

I have been working out at the Mountainside Fitness located at Chase Field, Phoenix AZ, for almost six months. I love it there very much. Cheryl and Joseph are two of my favorite staff there, especially Cheryl. She always greets me with a big smile on her face! She is so pleasant and friendly! She keeps the gym tidy and clean, and is always caring and asking what I need! I always feel welcoming there! I also love how much space they provide and how clean this gym is. The bathroom is so clean and organized. Thank you for all you guys do here and making the community healthy and happy! 😃

5/5 Stars – Mountainside Fitness is hands-down the best gym experience I've ever had! I've been a member at Mountainside Fitness for over a year now, and I can't say enough good things about this place. From the moment you walk in, the energy is positive, the facility is spotless, and the equipment is top-tier. What truly sets this gym apart, though, is the incredible team. General Manager Geena is an absolute superstar—she runs the show with such warmth, professionalism, and genuine care for every member. She's approachable, always checking in to make sure everything's going well, and she fosters an environment where everyone feels supported and motivated. Under her leadership, the whole staff feels like a family, and it shows in every interaction. The combination of state-of-the-art amenities and this exceptional staff makes Mountainside Fitness feel like a community. Thank you, Geena, Jack, Joe, Isaac, Ryan, Kolby, and the entire team—you're the reason I stay committed and love showing up!

Mountainside Fitness at Chase Field is hands-down one of the best gyms in the Valley, and the early-morning crew deserves special recognition. I’m in the gym at sunrise most days, and the consistency, professionalism, and energy from the staff—especially Jessica and Carlos—sets the tone for a great start to every workout. Jessica is always upbeat, welcoming, and genuinely helpful. She remembers members by name, keeps the floor running smoothly, and creates an environment where people actually want to show up early. Carlos is just as outstanding—professional, friendly, and always making sure the gym is clean, organized, and ready to go for that first wave of morning lifters. Their work ethic and attitude make a huge difference in the overall experience. The facility itself is clean, well-maintained, and has everything you need—great equipment variety, spotless locker rooms, and all the recovery options. But what truly elevates this location is the team that keeps it operating at a high level. The view is amazing and parking is convenient for downtown. If you’re looking for a gym with a positive culture, great amenities, and staff who actually care, the Chase Field Mountainside Fitness is unmatched. Huge thanks to Jessica and Carlos for making every morning feel like the perfect place to get after it. Highly recommend!

​"☆☆☆☆☆ This is hands-down the best gym experience I've ever had. The facility is immaculately clean, and the equipment is modern and always working. A huge shoutout to Joe, Gina (manager), and Ryan —they are welcoming, it really makes a difference. The atmosphere is positive and motivating, and helpful not intimidating at all. I highly recommend Chase Field's MSF to anyone, beginner or expert!" This is my favorite gym to get a good short or longer work out in.
