Clean, towel service, wet/dry sauna, kid-sitting services, massage chairs, and that's all the extras. All provided at a reasonable fee. They have a great variety of classes from tabata, spin, Zumba, old school aerobics to TRX group training sessions. It's all included in your fees. Great equipment, lots of free weights, a CrossFit like free open area, and a green belt. Although it can be busy at peak hours, most patrons are courteous and the guys give you space without creeping you out. You know, side eyes while you squa... read more

This Mountainside Fitness location is very clean and someone is always cleaning the vacant machines and honestly does not smell like a gym LOL  I've overheard a trainer working with someone and he was very supportive to his client. Pushing them and keeping them motivated. Well organized gym with something for everyone, even the most for the most advanced. We were always greeted with a smile upon checking-in. The bathroom (very clean). I did notice a couple people without proper gym etiquette by not racking their weights b... read more

I have been coming here for about 2 months now and it has honestly been a rollercoaster of an experience. Signing up was fairly easy, however apparently to use guest passes you have to sit there for 20 minutes filling out a bunch of forms while they badger your guests repeatedly to sign up. One of my "guests" went online and signed up for the 5-day free pass and when we got there, the member service girl asked if they were interested in signing up today, which they responded with "we're just checking it out today" and she to... read more

In February of 2023, Kalie Baker offered me a job opportunity to work at the front desk. I had an in-person interview with her, and everything went great. Kalie emailed me to extend the offer, and I couldn't have been more excited to start working at Mountainside. I replied to accept the offer that same day, and have heard nothing since. I followed up 3 days later, still nothing. Even if you moved on to someone else, at least have the courtesy to be a professional and let the person know. Do not extend an offer if you're no... read more

Disclaimer: PLEASE READ THIS BEFORE SIGNING UP I have been a loyal member of this gym for the past two years, but today I witnessed another act of discrimination and unacceptable behavior. I brought my friend to use one of my guest passes, and when I checked in, I simply informed the front desk that she was my guest--an arrangement that was accepted without issue. However, just a minute after we began using the treadmill, a female staff member named Taylor--who falsely claimed to be the manager--approached me in front of eve... read more
