Mountainside Fitness Arrowhead

I have really enjoyed myself coming to mountainside, working with Stephen has been really helpful. So glad i joined. The daycare crew is awesome too.

The staff member Tre at the front desk was very kind and respectful. This is my first time at mountainside fitness and he answered all of my questions and made sure I felt welcomed.

Kelly Ortega and the entire staff at Mountainside Fitness Arrowhead are a class act and hands down the best in the industry. Friendly, professional and great work ethic prevail amongst the staff at this Arrowhead gym …. even at 4:30am!!

I've done 16 classes with Brian for my physical therapy on my shoulder and back. Brian knows his stuff, highly recommend if you have any back issues neck, shoulders or anything else hes the guy to see. Keep up the great work Brian 👍. …

I have been going to mountainside for personal training with Phoenix for over 6 months. He offers a personalized approach that helps you meet your goals while challenging you. I have seen great results in strength and flexibility and would recommend him and this location to anyone I j ow.

Payton is a terrible customer service personnel (I believe he's the manager). I requested better communication since I was unaware of the location closing early on Halloween (Since standing outside I've talked to 6 other clients who were also unaware which seems to suggest the miscommunication is an issue). I suggested an email that reminds clients about different holiday schedules to a team lead but then the manager entered the conversation and seemed to think it was a stupid suggestion and argued with me which I didn't want to deal with. I canceled my membership because despite my attempt at constructive criticism I was mocked by mountainside management. I wouldn't reccomend mountainside to anyone based on how I was treated today.

I LOVE this gym. Because of my employer's generous wellness program, I've had the luxury of trying out this Mountainside & the EOS Fitness on 59th Ave & the 101 for the last few months. Although EOS is a good gym overall, has a pool, and is budget friendly, you definitely get what you pay for over there-- EOS is so crowded and has a very limited selection of group fitness classes to offer compared to this Mountainside (if it's this crowded NOW, what's it going to be like in January?). Also, as a Gen-Xer/working professional, the crowd at this Mountainside is more my vibe-- I swear every time I walk into EOS I feel like I set foot into a nightclub club (90% of EOS's gym-goers are Gen Zers/younger millennials that appear more concerned with hanging out than actually workout out). Mountainside's staff is super friendly/responsive (shout out to Phoenix!), the facility is well-maintained/clean, the class assortment is phenomenal, their childcare is open longer on weekends compared to EOS, and the towel service is a nice convenience!

I’ve had a membership at Mountainside for years now. Clean gym, friendly staff and great personal training. My trainer Tomas Dobre consistently shows me creative, fun ways to tackle my goals!

Real chill gym, friendly staff, never have trouble using equipment, kept clean mostly although sometimes the mens locker room is grimey(seats at the lockers and other areas) I've had other memberships in recent times where they were a bit better at keeping things clean in there.

My wife and I have been working with the trainer Phoenix for 6 months now and we couldn’t think of a better trainer. He’s been super flexible adjusting to our differing schedules, very responsive, and he creates workouts based on our goals. I had an existing injury prior to us starting training and Phoenix has adjusted our workouts to accommodate so that we both still get a good workout and see results even with reduced movement options. If you are someone who is committed to reaching a goal, there’s no better trainer than Phoenix to get you there!
