I have had the pleasure of visiting a number of the mountainside location and although it would be hard to say which I my favorite. The Peoria location is by far one of my favorite locations to go to. The environment by itself sets it apart from a number of competitors. The members are what truly make this location so excellent and for as much traffic as this location sees it is also one of the most well-kept. For the sheer number of people using dumbbells and free weights for them to be as organized as they are it is impres... read more

Definitely the best gym around. Not only are they Friendly but they are also Clean. They continually add new equipment and are updating the facility. They offer amazing classes and their personal trainers are so helpful. Their childcare is the best, with so much to offer, my kids love going. From family memberships to individual ones Mountainside is the only place I'll go! 

Business response:

Dani, Thank you for taking the time to leave us a 5-star review, we really appreciate it! We value what every single one of our members has to say about our gym and we are always open to ideas for future renovations and areas of improvement. Thank you, and have a great weekend.

This location is in desperate need of an update! Old equipment and atmosphere. With such a growing area, this gym is not nearly up to par with the desert ridge, happy valley or arrowhead locations! Sad because so many new homes and families but one of the lowest quality locations in the valley! Please update! 

Business response:

Lauen, We would appreciate a chance to improve your experience with us. Are you open to having someone from our team reach out to you separately? If so, let me know. Thank you!

I've been consistent in the gym for nearly 20 years and I always appreciate the kind and warm greetings I get from the staff at this club. When you go to a gym 5-6 days a week it's easy to be overlooked when your a regular. It's always nice seeing someone here, from Michele, Stacy, Dani and Zach (and many others), I always have great vibes and energy seeing them. Keep it up! #MountainsideAdvocateAdam D. 

Business response:

Adam, We are so lucky to have you apart of the Mountainside Community it's been a pleasure! It makes our day to see you in our gym frequently as much as it makes your day when we recognize you. We are happy when our members are happy, so thank you for taking the time and leaving us a review. We really appreciate your continued business, have a wonderful week!

My fiancée and I just moved to the area and we were looking for a gym that met our needs. We were so happy as soon as we found this gym. It has everything we need and the staff is fantastic! We did some training sessions with Ryan who is one of the personal trainers there. He was very informative for each exercise and he gives you the perfect amount of encouragement throughout each session which will help you get into great shape! 

Business response:

Hi Mark, welcome to Arizona!! We are happy to have you and your Fiancé apart of the Mountainside family. Our Happy Valley location is very unique and we love all the different components of the facility. Between the different rooms for cycling, yoga, and group fitness we offer such a wide range. Thank you for your 5-star review. We hope to continue to make you both happy :)

I go to the peak class on Saturday morning with Ayla Nelson as the instructor. This a great all around class and Ayla is very motivating and fun. I have been going to this class since November along with personal training and other classes and have seen a big difference in my strength and fitness. 

Business response:

Susan, We're so happy to have you in the Mountainside family! Ayla is awesome and we are happy to hear you think so as well. Keep up the great work, and we hope you continue to see your strength increase throughout 2019!

I got myself looped into using a personal trainer, which worked fairly well except none of the times available worked well in my schedule. Then, I ended up very sick and kept trying to cancel the monthly fee of $250 for the personal training. Apparently, I was supposed to contact Jordan "only." Could not go in without exposing others to flu and then pneumonia, had laryngitis and a horrific cough that kept me from anyone hearing me on the phone. Sent text and e-mail, but nope...must only see Jordan directly. Tried for two wee... read more
