Awesome! Do Stacey's classes.
I love Mountainside Fitness! I love the classes. They been super fun & helpful for my fitness journey.
I love the classes here like muscle class, yoga,barre class. they have a lot other classes too. I also like the infrared sauna too. over all I recommend this place to all
why don't the screens fully load? it's been all week. I can click on the middle of the screen but the images don't load. well I just uninstalled and then installed again, and seems to be working better.
Amazing gym with great classes. This app works great on for booking classes, receiving messages from instructors and getting virtual workouts to do at home.
This app does everything I need it to do and is simple to navigate.
I've been coming to Mountainside for a very long time. It has always felt like a 2nd home. I go to 75th and the 101. Mindy is amazing and is such a great help around the gym. count on her for anything.
love that gym
Mountainside fitness is the perfect gym for me. They provide extras like free towel service, red light therapy, cold plunge, and machine availability is good. They offer a variety of classes to meet your goals. If you are tired of being a number crammed into capacity crowds, Mountainside Fitness is a reasonable alternative. The operation is well run and helpful.
doesn't let me login.
CYCLE etc. 👍
Really Enjoyed My class
I am a new member and am very disappointed in this app. First, I have tried to update the profile tab multiple times, and on different days and it is not accepting the updates but not giving an error. Secondly, it does not keep track of your gym check-ins, unless you book a class. And you cannot see future billing information. My old gym app was way better.
Best gym ever. equipment is top notch and so is staff
I really like the gym, clean, organized, and professional.
Many choices of classes and great instructors.
The advertisement banner is obnoxious, it takes half the app screen, what is the point of this?
Zumba with Michelle is great
The app says to go to home, click on profile, and enter your bar code number; however, on a Pixel, I am unable to interact with the bar code cell at all which effectively renders this app as utterly useless. Since I cannot connect my account to the app, the app is broken, and my time has been wasted. My wife's iPhone has an identical problem. Conclusion: the app is broken.
App barely works only good thing about it is I don't have to carry my key card that I already lost. all mvirtual class videos are met with file errors.
Excellent atmosphere, love the classes and not too crowded.
New, clean facility. Great dim yoga room and great instructor.
How bad is this app designed? Per person in charge or publishing this app should be fired.. I can create a better one without all the confusing and non-explainable icons. Not to mention that most are not even working. Please get your act together. This is not the 90s. Those ugly icon designs should be banned. Let me know if you need app developer......
fairly new with a clue on what to do for health in you
good vibes. like the selection of different classes and schedules
As a new member, I've attended 2 yoga classes and a simply stretch one in the Serenity room. April was even able to help me participate without any of my bothersome dizziness. I left feeling better every time. I can't praise the child watch program enough. The incredible staff supervise many varied activities.
Okay but show our check-ins.
I've been going here 3 months it could be more grab three times a week and everybody is nice
beautiful clubs with something for everyone.
Many group classes to choose from. cold plunge . dry and steam sauna. towels included.
lots of locations. love the classes. staff is fantastic. best gym in phoenix
love being able to book classes through the app but I wish it gave you a time stamp of when you put your kiddo into the daycare so you know exactly when you need to be back to grab them.
joined recently and am already thoroughly impressed with everything. the classes aren't too packed. I like signing up the night before. the locker rooms are clean and spacious. and you can't beat having a steam room and sauna to enjoy. love this place! I'm so happy I joined.
Great classes, massage chair, nice equipment selection, clean, and I respect how they handled Covid- they were always cleaning and separated equipment.
Place is awesome, judge free zone! All trainers are well educated and respectful. I recommend getting a membership here!
MSF continues to implement more restrictions on their app, yet fail to share their newest updates with their users. MSF now also charges an extra monthly fee if you'd like to book a class more than 24 hours in advance. Just another company getting more greedy and going for the cash grab.
Best place I ever worked out at. I travel for work and this is my far best ever.
works great and plenty of features. enhancement request - faster way to switch between class schedules by location.
The app is awful. it takes forever to load, will just spin and spin when trying to book. Mountainside needs to invest in improving their app!
I enjoy all the locations and each gym is very clean. Always have towels available.
Enjoying the Aerobics with Summer, she makes the classes fun!
Good app, sometimes, it has issues connecting to server for booking classes but other wise good tool
Love my gym. Plenty of different classes and great instructors who motivate you and keep it fun
Awesome gym!!!!
Excellent Gym and great classes!
Quiet, clean, and peaceful gym. They even provide mouthwash!
Good gyms with great value. Kids club is included. I highly recommend them.
Update of app is required but there is no way to update it. Maddening.
Love the yoga. At my age, I need to stretch.
amazing instructors for dance fusion and hip hop!
Great yoga class with a phenomenal music.
very clean, towels always available. plenty of classes in the am as well in the evenings.
I'm 65 and been a member for a couple of weeks. I'm struggling to find the right fit. my first time joining a fitness club. super nice people working there.
One of the best gyms I have gone to with a variety of classes to go to.
Love ❤️ the classes. Instructors are wonderful!
the staff are friendly. the facility is clean. the classes are great. best workouts I have ever had. so happy I joined! I highly recommend Mountainside fitness
friendly staff. Good instructors. clean facilities
would be great if you could "find a class" across the locations within a mileage from house
you have the best instructors! Jennifer v is amazing. but I do love them all
Was fun while my gym membership lasted.
Awesome App if your a member
Best clases and great instructors.
great gym!
Cant even setup barcode because birth date entry in app is bugged.
I have been getting invalid server response error as the last few days, other than that it's a Pretty good app all in all, it would be nice to be able to search across clubs for a specific instructor or class
Great gym and staff!! The group fitness classes are awesome too with amazing instructors!!
need better cross-club search- e.g., all yoga classes today anywhere
love Mountainside!
inly search by location.. needs functional overhaul. must rework for users to search by day/time and by class type
Have membership n it does not allow my barcode says it assigned to someone else's e mail??
This gym is very clean and the employees are very nice and helpful. I would recommend joining. They have lots of glasses and equipment.
It's got my barcode which is all I use it for so... It's fine.
Nowhere to register an account, only has a login option.
😴😌😕🧐🤠💋🤎😾💓😾👺🖤
Nothing on this app works.
Read the contract carefully before signing. They charge 25$ extra for simply signing the contract and I took general per month is 42$. Very expensive gym. I heard there are many gyms around of range between 10-30s. I joined few months ago now I cancelled the membership for next month and forever.
Cannot open the virtual workouts group fitness on demand or archives using the vimeo link. Message says unknown URL. I can start the recording but it is a small screen with no icon to make it full screen. I have a Samsung Android phone. I also cannot go thru Chromecast to add the app to our new Samsung smart TV. Message says app is not compatible with device. I am think this is an iphone apple app and not android. I have called MSF for assistance but they cannot help me. Not happy.
This is a great app which helps me easily check in to the club and make bookings. The user experience is great without taking too much time to get around the menu's.
Junk! Can't log in even after creating an account and receiving a code. Used the code then you can't log in , it says invalid user!
Barely works. And none of the features work all the time.
Several attempts to register failed. Due to new rules to schedule an appointment with app, I am unable to.
This app is subpar. Half the links don't work. Limited account information.
I am unable to download the app. to schedule a workout.
The download ability of this app is just as shity as the app. Been trying for 2 hours to download the app still can't download it
This app keeps changing. Now it seems that it no longer shows the log of my visits.
This is a great App. You need to sign in and creat an account. Call your club if you need help. It's so easy to sign up for classes and pick your spot. I've been going to Mountainside for 9 years. Great instruction and personal training.
Seriously, this app is the worst app I have ever used. I ended up at the gym to get it straightened out. It was working when I left the gym and now 5 hours later I get the dreaded Error at the server, try back later. Are you kidding me. This app sucks!!!!!!! Jack Berwind
Why even create an app that doesn't work? Cant log on. It does not recognize my log on info.
Constantly get "Error at server" and blank screens. I cannot reserve a spot in any classes. I have closed and opend it 5 times, uninstalled and reinstalled 3 times and it will not work.
I can't get any where through this app. There's no "live" workouts for me to go back to as it claims and logging in for an at home workout is the same exact information that's public knowledge....
Awful. And pointless. I can't even see my check ins. I used the older app as long as I could but now it's been disabled. This app is horrible, looks awful and I have no use for it. Sorry for the negativity but that's how I feel about the app. Alfonso from the Surprise Gym
Is there a way to rate this negatively? Can't log on Doesn't recognize email address. Can't get into the app even after uninstalling several times. Oh yea, wife has the same issues and we signed up 2 plus months ago.
this app is terrible. does not work. so tired of mountainside fitness updates.
I cant figure out how to check class schedules at multiple clubs unless I constantly change my home club. I visit 4 clubs a week based on classes. At least previous app I could easily change location. HELP
This update is worse, I can't even view my check ins. The last app was better then this one by far! The only way to view your check-ins is through your club account through and iframe is this 2000? Talk about going backwards
No help with app, how does a person input themselves if it's a family membership. 4 people on the membership. It does not tell me how to add individuals.
This app is awful! The original app is so much better. I'm super tech savvy and I can't maneuver through this mess of an app.
Doesn't open
So far I've had the same log in issue with this app that I had with the previous one. The app is trash; either keep your barcode tag or just sign in at the desk.... I'd almost consider giving up my membership because this app is that bad!
