Great gym almost as nice as lifetime fitness looks like a great gym when I was not able to go to lifetime I was able to go to Mountainside fitness and I enjoyed it a lot. They have up-to-date equipment and they have nice people that work there. Good employees they are friendly and helpful.

It has the machine i like to use and the young staff are super friendly. Its the sensory overload that is perpetually annoying, bumping music i can hear through ear plugs and headphones an hurricane fans constantly keeping the floor dust in motion. Dont get me wrong, background music is a great part of setting the atmosphere in a gym: the songs are fine, i just wish i could drown it out on the treadmill (where their music is loudest).

In town for the weekend. Walked into this place looking to buy a 3-day pass to work out. Was told it would be $25 for a 1-day pass. Skip this rip off and find a real gym, especially if you're from out of town. Just looking for an oss place to get a workout. Total joke. If I could leave zero stars I would. Out of towners beware

The MSF Happy Valley location is very spacious, and busy, but a busy gym is a popular one! MSF has always been good to me and has never taken the wrong approach and given me a great experience at various locations. I will always suggest and recommend people to join Mountainside Fitness!

Because I had an issue with one of your absolutely unprofessional acting managers. I will never set foot in your establishment ever again. I've already joined another gym. And their management team absolutely absolutely acts professional.

This gym is quite larger which is great! It is newer which I love. Testing out a 5 day pass. I use to have Mountainside but it is a pricier membership compared to EOS and not as convenient. I work in the medical field and needed a gym that was open 24 hours a day and so I had moved on to EOS. However now I am looking into coming back since my schedule has changed. Few things: MF use to give membership discounts for healthcare workers and that is no longer posted on their website. They seem to honor 1st responders which is gr... read more

I've been a member at this gym for almost 9 years, attending multiple times per week and varying locations. I really love Mountainside! The staff are courteous and friendly. The few minor issues I've experienced over all those years have been immediately fixed by knowledgable staff. I usually attend classes and really love their instructors! I am excited to go workout now, never thought I'd feel that way! The member community is mostly very pleasant and I've made quite a few friends over the years. The gym is always clean an... read more
