Mountainside fitness is a fantastic gym! The staff at the arrowhead location are so friendly. I was lucky enough to have Jordan G as my personal trainer. He is by far the best trainer I have worked with! His knowledge of fitness and nutrition is exceptional and he has a great personality! I highly recommend Jordan if anyone is looking for personal training! You will not be disappointed!

This place has a great location right off the Loop 101 and 75th Avenue. The staff here are on point and very friendly. The layout of these location is one of the best I've seen in a Mountainside Fitness. I like how the Cardio doesn't face the machines and free weights like most gyms do. It takes the whole meet market feeling out of the atmosphere. The places seems to be pretty well laid out. The only think is they need more leg machines. And a standing Calve machine. They never have enough or the right pulley attachments. Th... read more

When Mountainside was founded, the motto was "the friendliest gyms in town" and they definitely are! The staff at this location are always so friendly. I'm always promptly greeted by a staff member with a smile and great attitude. I've been to many gyms where the people checking you don't say a word to you and often times put the scanner on the counter as to have customers check themselves in. I've never seen this at any of the Mountainside Fitness locations and not that the others don't have great staff, but I definitely th... read more

Been going for two weeks now. This gym is wonderful!! People are super nice and the classes are amazing!! My only critique is that I believe the childcare is extremely understaffed. In the mornings dozens of babies crying on the floor and a line out the door waiting to drop off more babies and kids with only a handful of care takers. I just signed a membership with childcare but will be dropping the childcare part until this gets better. You can tell the ladies are overwhelmed and cannot possibly properly watch so many at on... read more

As a previous member of 24 hour fitness and LA fitness.. Let me just tell you.. This gym blows them clear out of the water. Not only is the equipment new and the entire place spotless, but you get free towel service both hand towels AND shower towels!! This is so big for me because I usually shower at the gym especially if I go before work. AND they have hair dryers in the women's locker room, body lotion, and q tips. You can pay extra for the "executive lockers" where you get your own name plate on it, and can leave your st... read more

I had high hopes for this new gym but they already have equipment pieces out of order. The equipment is not getting repaired and its approaching 3 weeks! Unacceptable for the over $40 fees they charge per month. 

Business response:

Thank you for your feedback. I sincerely apologize for the inconvenience of the machines being down and I understand your frustration. Your experience is important to us and we never want to see equipment down. The only time a machine would be down for a period of time would be when we are waiting on parts that have been ordered. We always try to fix a machine right away for our members. I am always available to you and am happy to answer any questions or address any concerns you may have. Always please feel free to ... read more

I was very uncertain about signing up for a personal trainer as all of my prior personal training experiences ended after 1-2 sessions. I have an extreme fear of looking stupid in public and have found that the personal trainers I have met with have a set of things they want you to do, regardless of your feelings about it. Brian Lawson of Core Concepts met with me initially, heard my concerns, and told me he would match me with someone. Brian assigned me to Shauna Meredith who has been great! On my second session, I decided ... read more

What's my goal? I have been attending Mountainside Fitness/Core Concepts @ Arrowhead to get my body into shape and prepare for a healthy pregnancy. After talking with the fitness director about how to effectively t-t-t-t-tone my body and reduce body fat and strengthen my muscles by getting professional individualized instruction with a trainer, I was sold. He paired me with Jordan Guida. I purchased 1 training session per week ($30-something/week) for the year and got more than I paid for. Jordan consistently goes above and ... read more
