The roof to the basketball court started leaking while my son was playing him and 3 other kids got hurt. I canceled my membership due to this not only am I still being charged but now I’m being told I have to come in again to cancel a membership I have already canceled and I live 2 hours away. I would not recommend this gym to anyone there’s broken glass all over the turf from the mirrors it’s just ridiculous

Excellent gym. For my work I travel all over the valley so it’s a huge benefit for me having a reliable gym in each pocket of the Phoenix metro. The cardio, weight lifting, and recovery facilities are all top quality.

My only complaint is the gyms are shifting to infrared saunas. They’ve improved on the heat for them to compare to dry saunas, but the cleanliness is disappointing. Often times the floors are very dirty. IMO, there should be sweat guards and a no outside shoe policy.

Otherwise, mountainside fitness is an excellent gym!

I’d love this give this place a good review being that’s it’s new and has great amenities but the customer service and cleanliness overrules all of it. The fact that we are paying more than competing gyms surrounding us and the locker rooms are unkept for, the steam rooms smell like mold (probably a safety hazard), and the literal KIDS that work here have no sense of professionalism and work ethic is insane!!! Every time I come in the locker room, the “staff” is sitting around on their phones as if there’s nothing to do and it looks a hot mess.

While visiting the area on leave, I visited this club to inquire about a pass. I was initially told that I could obtain a 5 day pass at no charge, which is a great thing to offer. Unfortunately, upon finding out that I'm not an AZ resident, I was turned away. I'm in town visiting family while on leave and of course need to get a work out in. The staffs alternative was to offer me a week pass at $50 or a daily for $22. Absolutely ridiculous! I'll be headed to EOS where they offer free 7 day passes with no abbed ambiguity over a military ID and my lack of residence in AZ. Shout out to Nick at EOS in North Scottsdale for helping me out!

I can't say enough good things about Jessica in the child care center at Mountainside Fitness.

She has such a warm, kind presence and truly goes above and beyond to make each child feel seen, safe, and happy.

Well-Equipped Gym in a Prime Location, but Cleanliness Needs Improvement. Mountainside Fitness location on Frank Lloyd Wright in Scottsdale benefits from a convenient location and a relatively new facility, with modern equipment and a wide range of amenities. The gym is spacious and well-equipped, making it a strong option for fitness enthusiasts. However, it tends to be very crowded, particularly during peak hours, which may affect the overall workout experience. One area of concern is the cleanliness of the women’s locker room. Despite the facility’s newness, the bathrooms and showers often appear neglected and would benefit from more frequent and thorough maintenance. This lack of attention to hygiene is disappointing and detracts from the overall quality of the facility. For those who can overlook the high traffic and are not reliant on the locker room amenities, this gym still offers a strong value and a comprehensive fitness environment.

Gym is nice. Staff is friendly. I would’ve gave this gym a higher review. If only they figured out how to get their infrared sauna’s working properly it seems like they were improperly installed with wood beams covering 35% of the units on the walls absorbing all the infrared waves that should be going into your muscles instead these waves are going into the wood. These unit should have a screen on them similar to howa speaker from a stereo system that produces sound waves you wouldn’t cover your speakers with a bookshelf wouldn’t make sense? most infrared saunas I’ve been in have all had some type of cloth screens over the units, not blocking any of the waves that benefit you, but in the sauna and at this location 35% of the units are blocked with 3 Wood beams not letting the infrared waves penetrate your muscles There’s no infrared units on your legs or feet. It just seemed like there wasn’t enough units in the sauna to be beneficial.?. Sauna was cold 118° degrees spoke to different individuals and was told Sauna needs to be reset every 90 minutes. and if it doesn’t, it’ll turn off I spoke to general manager he did not understand what the other employee was talking about? The women sauna was at 165 and the mens sauna was at 118. I was hoping it would go higher if I sat in there for over 35 minutes my heart rate never got over 83.. lots of red light but just for show The red bulbs in the unit don’t do anything besides ambience, which is nice to look at but not beneficial in anyway, infrared sauna was not working the five days that I was there. The door to the infrared sauna had a inch space at the bottom of the door, letting all the heat out not closing properly sauna was big very nice, but it just seems like it needed more heating units that actually worked and were properly placed The other downside to the gym are the huge fans that are on the main floor and blowing air at very high speeds. I like to be warm when I’m working out, so I don’t strain any muscles but instead I was cold my eyes were drying out from all the wind that was blowing out down . I think they should have them on the lowest setting as I tried to stay away from any blowing air even in a restaurant if I’m sat underneath an AC unit, I will ask to move. I do not like air blowing down on me and it’s not beneficial to a proper workout. I was ready to sign a one year membership, but after my trial membership, I think I might just try a month and see how they’re doing. I know it’s a new gym, but I think they should work harder to get the infrared working properly and have more of an enjoyable atmosphere when working out Not having to worry about getting sick from being cold. Other than that, the gym ohh is very nice. I just think they need to work harder on the sauna and maybe doing a little cleaning mid shift men’s locker room just wiping down the counters and the mirrors but other than that everything was good. I hope to go back and see if they have improved on this as I really liked the gym but I am a huge hot sauna person and do not like air blowing on me at high speeds so I’ll keep looking …steam room was good. if they fix those hiccups, I would give them five stars. I hope the owner reads this and understands exactly how the members feel or future members because he does live here locally so it’s not that corporate yet but I invite him to sit in his infrared sauna for 30 to 40 minutes and see if he finds it beneficial an optimal heart rate would be around 145 to reach after being in there for 30 to 40 minutes if they fix these problems, they would have a really nice gym. And to have everybody on the team knowledgeable on how infrared sauna’s work proper temperatures and all the protocols that need to be done to have them working properly throughout the day. Sauna is a huge part of my day I give there’s a F rating

I’ve been a MS fitness fan since I stepped into one. This gym has been great until recently. Today I had a very odd encounter with a guy who started to inform me that I cannot put away my own safety in a safe location off of the gym floor despite already having permission from faculty to do so for well over 2 months. After getting very demanding he guessed my name incorrectly and finally introduced himself claiming to be the GM. Very unprofessional and insecure from someone who claims to be in such a position. He informed me that if I do not take the equipment home with me they will “take it out and do something with it” and when asked to elaborate he would not tell me anything if my bar were to stay. He then proceeded to follow me into the locker room and badger me. I would greatly appreciate if I could be contacted by management above this so called “manager”

My husband is a member so he got me a 5 day pass. After 4 visits my thoughts are these-
The Women's Locker Room is super disappointing
- Balls of hair in the shower and on the toilets.
- Women wearing their gym shoes in the sauna and steam rooms and putting these shoes on seating & benches. Do they not know locker room etiquette? How gross to put your filthy shoes from outside in these spaces! Also, please mute your phones when in these rooms. NOBODY wants to hear your conversations or be bothered by whatever you're looking at on your screen. It's SUPER RUDE and not the place for your phones.
- USE TOWELS! Again, so many women sitting on the benches near lockers and in the steam/sauna with nothing between their sweaty bits and public areas! Grab a towel and sit on these please!
My husband told me the Men's steam room has people shaving in it?! Again. GROSS and not how it works!
I've emailed and left word with this gym requesting they place signage in the area and have seen NOTHING posted or a response to my concerns.
The equipment is fine, haven't tried the classes yet but as of today, would not be interested in becoming a paying member. Not an isolated opinion as other same reviews here.

Unless you feel like selling your soul to this place, stay away. When you sign up, they're super nice and friendly. They promise you the moon, stars, and everything in between, and try to upsell. Then the switch everything and become nasty once you're in. As another reviewer said, predatory billing practices.

The actual trainers are amazing. But past that, I signed my son up for three months to see if he would be interested and I specifically chose three months so as not to commit. He wasn't a fan, now I cannot remove him from my membership, and despite letting them know in writing and DRIVING to the gym to talk to someone who assured me his training was canceled, I was charged again this month. I had changed my own schedule from 30 min to an hour, and was told I could change it back. WRONG.

Which brings me to the next issue. You cannot communicate with anyone on the phone or via email, you must take time out of your day to drive there. Once you do that, if the one person who can assist you isn't there, you are SOL. When they do message you and tell you when to come back (in this case the weekend), and you reply that you will have to set up a different time, they simply don't answer the message.

I'm guessing they make commission and that is why they feel the need to lie to customers. I thought Lifetime was bad - this place makes Lifetime look like a saint. Make sure you sign up via cc not your bank account too, because they are unethical. Don't know if it's just this location or the company as a whole, but the rudeness/lack of customer service and bait/switch tactics are disgusting.

I started working out at Mt side fitness following a shoulder injury. My trainer is adriel brilliant and I do not have enough good things to say about him. I will admit to.having some trepidation when I first started because I was very worried about the possibility of re-injury, but I found adriel to.be very knowledgeable, and encouraging. He allows me to " train to failure", meaning I can push myself to my personal limits (which i love) while he is very attentive to.my form and ensures that I am training safely. At my age (73), I find that he has made me aware of my negative self talk and always hits the right balance of letting me push myself while maintaining good form and not re-injuring myself. I learn something new.from.him every session and he is always very respectful. My whole experience at mountainside fitness has been colored, in a very positive way, by the fact that i train with adriel brilliant!
I would like to.thank adriel for his great.training and give.a.shout out to HR at mountainside fitness for the great hire!

You know that Friends episode where Chandler and Ross just want to quit the gym? Mountainside Fitness is this exact experience. I joined when this location was brand new. I had 2 months free (Sept and October) and prepaid for the “final” month. I tried to quit the gym in October which meant I shouldn’t have been charged as November was prepaid. Instead they billed me. Spoke to 3 different people including a manager who assured us the month would be refunded (because I shouldn’t have been). I challenged the charge on my card which has now be charged back to me based on the gym’s “response” which was simply to show them my gym membership contract. Which proves nothing. Cherry on top? They never refunded the original amount so I’ve just been charged back the same funds with no refund. Wouldn’t rejoin this gym if it was the only option in the valley. Predatory billing with incompetent staff.

They ended up getting a deadlift bar, which I haven't seen at any other Mountainside yet. Which is great and a standard piece of gear at lifting gyms. Nice!

Great layout. Lots of space and equipment.

Recently switched to this location because my kids are absolutely in awe of Jessica in childcare! She has all the best tricks to keep them entertained, and they never want to leave. The facility is clean, with great equipment that’s well spread out, so there’s no waiting around. This is the place to be.

Great gym until you walk into the locker rooms. Smells like the whole citys sewer system has backed up into the locker room and is fowl. Steam room and showers also needs to be cleaned more often as it has hair and dirt on the floors.
Gym itself is great. Good equipment. Good staff.

A long-time member of Mountainside Fitness, recently checked out one of their newer locations. I also have other brand club memberships as I travel a lot where MS Fit is not but I'm always glad to come to my Mountainside home gym when I return to AZ!

👍 Tons of equipment for every kind of workout you would ever want to do. And some very expensive high-end stuff not generally provided at a gym at the price point.
👍 Basketball/Pickleball court.
👍 Very clean all the time.
👍 M- Cafe is a nice option for a smoothie or a protein drink. They even have cold brew coffee (although I do miss the days when they used to offer free hot coffee).
👍 Towels provided for workouts and showers.
👍 Plenty of cleaning wipes, Kleenex provided throughout.
👍 Several membership options including pre-paid and monthly. It's very reasonable for what you get in comparison to other places. All memberships include access to almost all clubs. For me, the Premium is not worth it as I get a lot more Premium services at another gym for less; however, that gym has other things MS does not (trade-offs depending on what is important to you).
👍 Great amenities, sauna, steam room, cold plunge (extra fee), lockers (with locks), mouthwash, lotion, and Q-tips. Small storage & charging stations. Massage chairs (extra fee/membership type).
👍 Having utilized their training staff over the years, I have always been happy with the caliber of trainers and pricepoint (look for specials). Group fitness classes are also very good.
👍 Good hours (appreciate the 4:30 am open time for us early-birds on weekdays and 6 am on weekends). One or two locations with 24-hour access would be nice but perhaps would not be busy enough for them to make business sense.
👍 Good kids program. One of the better for most gyms.
👎 They don't have pools or hot tubs so I have another membership at a gym for those options. But I get that these are expensive things to operate that don't always get used and I don't go to Mountainside for a swim, it's my main go-to for everything else.
➡️ Pictures taken at 6 am on a Sunday.

Smells horrible in the women’s bathroom and has since it opened—seriously like rotten eggs. Like, embarrassed to bring family horrible. It’s been like that for a long time and the staff just keeps saying “I know! It’s terrible!” So gross!! No solution.

Also, they let teens take selfies in the locker rooms and no warnings anywhere about it being illegal so anyone could end up naked in the background—do not get dressed in the open locker area there.

This gym is immaculate. Absolutely gorgeous—until you step into the women’s locker room, where it smells like someone took a steamy, wet dump on a pile of gym socks and left it to ferment in a sauna.

The stench is so aggressive it doesn’t just hit your nose—it slaps your soul. I walked in and immediately regretted having nostrils. You know the smell is bad when you start mouth-breathing and it still feels like you’re chewing on someone else’s bowel movement.

And the worst part? It’s been like this for months. MONTHS. I don’t know if management’s nose is broken or if they’ve just accepted this locker room as a biohazard zone, but it’s unacceptable. Is there a sewage pipe directly venting into the room? Did someone eat a family-size Taco Bell meal and decide to ruin lives? Whatever it is, the smell needs to be handled immediately.

Until then, I’ll be suiting up at home because I refuse to marinate in the aftermath of whatever gastrointestinal war is being waged in there.

They don’t have a traditional dry sauna, just an infrared and it is an upcharge when the sauna comes as part of the standard membership at all other locations. In my opinion, infrared is a gimmick since it doesn’t get as hot as a traditional dry sauna, so it’s certainly not a direct replacement, and it’s certainly not worthy of an upcharge. I wanted to give this location a shot since it’s newer than the FLW and Shea location, but the decision to not have a traditional dry sauna is a complete deal breaker for me.

I’m returning to the gym after sometime and I felt so overwhelmed. I decided to do the consultation with a trainer and had the opportunity to work with Shannon. Shannon was so patient, kind and motivating. She was able to give me a good routine while building my confidence and has helped me reignite my excitement for my health! Thank you, Shannon!!

I absolutely LOVE this
mountainside location, they are all great but this one is special.

The gym itself is awesome multiples of everything. And. So. Much. Space.

But, the childcare is really what sets this place apart: every time my kids get dropped off they are greeted with loving staff that remember their names, make the kids feel special (so much so they get hugs now) and I know they are truly taken care of.

Lauren, Brie, Morgan, Izzy…you guys have truly made me boys feel loved, special and I am so grateful for how well you take care of them. You guys mean the world to us! ❤️

Several of the machines are not put together right, they do not go to full extension as if whoever put them together was 4ft tall and short arms. Also the dry sauna is WEAK, literally takes 10 min before you even get a drip of sweat

The locker rooms are consistently unclean, with dirty towels left everywhere and the towel drop often overflowing. It creates an unhygienic and unpleasant environment for members.

Additionally, the sauna is ineffective—it’s barely warm and far from meeting expectations. Despite bringing these concerns to management multiple times, no improvements have been made. If anything, it seems the sauna’s temperature has decreased further.

This lack of responsiveness and quality feels like a disservice to members who trust in and pay for a well-maintained facility. I hope you will address these issues promptly to restore member satisfaction.

Great gym! All new equipment, beautiful on the inside, friendly staff. The only downside (which is huge for me and a big reason I love mountainside) is the sauna. It’s been broken for over a month! The gym just opened, and the sauna is already out of order. Its been broken longer than the gym has even been opened…

I understand, wearing shoes and workout clothes in the sauna that some people think negative thoughts but I don't know about the steam room. But even lifetime fitness is doing the same thing. Not everyone wants to be naked in the sauna or steam room. Which is okay. I don't see any problem with that.

I have been to the most expensive gym in the valley and I always go to the sauna or steam room wearing my workout clothes 🤣

This gym is well diversified with equipment and provides tremendous amenities. I believe they are a 5 star when it comes to equipment and overall space.

Although I changed gyms and bought this membership due to the cold plunge that is available. I am strongly disappointed that after a few uses of the plunge, the “cold” is non existent and turns into just a tub of water. You won’t be able to reap the benefits of a cold plunge when the water is sub 60 degrees. If properly managed this gym is easily 5 stars.
