One thing I've been enjoying is the peloton workouts available on the TV in the back room. The gym is always clean. I've only had good experiences with the staff. Of note, there are no locker rooms.

I recently joined Mountainside Fitness and expected a time consuming sign up process with extensive…read moresales pitches to try to get me to sign up for more of a membership than I needed or could afford. I was pleasantly surprised when Bailee streamlined the process without any pressure. She also offered me free trials of membership benefits like the red light therapy and the brand new cold plunge! Bailee was so friendly and helpful in assisting me in deciding on how to proceed with my membership choices in a non committal way like I wanted. A gentleman named Jake gave us a tour and was very respectful of the limited amount of time I had to spend on the tour. He also explained all about the included classes and ammeneties available at each location! A great part about Mountainside fitness is that they allow 12-year-olds to join so that means my daughter can come with me! I could not find another gym in the area that allows children under 13 to attend so I was really pleased at this privilege. I also liked that all the memberships allow you to go to any location.! I'm really grateful that Bailee was there to help, being that she was so knowledgeable on the membership options and perks! P.s. I love the cold plunge!

This was my first time visiting this gym and I went as a guest. There were a lot of cool things…read morethat they offer. The equipment offered a range of machines and I like the way they separated the equipment upstairs, and into different rooms downstairs. They have a few rooms to play different handball and croquet games. There is a basketball court , sauna, whirlpool and swimming pool. The restroom/ Locker room was very clean . The only thing I didn't care for was looking at the pool, it can use a facelift. The bottom of the pool is discolored and needs to be redone . Same with the whirlpool. There were also IMO, not enough cleaning areas. None were close enough while I was working out. I had to search for the cleaning stations. That leads me to believe that a lot of people don't clean the equipment before or afterwards. I made sure that I did because I do no want to get sick from other people germs.

The main reason I come here is to swim, since there either aren't pools at the other locations near…read moreme or they're indefinitely closed (McCormick Ranch). So, yes there is a pool, but it badly needs to be resurfaced. Whole pool area seems rather dingy, severl of the lighting fixtures don't seem to work. There has also been a leak in the wall in the pool area (not in the pool itself) for months that has gotten progressively worse. The whole wall area has bubbled up and is molding, with the tile floor at the bottom starting to look pretty nasty. There has seemingly been minimal/no attention given to this. The rest of the gym looks pretty spacious, locker rooms are decent.

Long post alert! This is a note for folks of all ages,…read moreshapes, and fitness levels: So. I was the person who talked to countless gyms after my own gym closed without notice (Burst! Fitness). Prior to Burst! I was kind of a gym drifter. EOS, LA Fit, Planet Fit, Crunch Fit. I tried them all on for size. Didn't like them (nothing wrong with them, just didn't quite meet my needs). The search continued. I started deep-diving on the internet. There had to be an existing place out there that fit my needs right?? Over several months and consultations with private gyms in Tempe, Phoenix, and Scottsdale- Underground Fitness showed up on my radar. Leading up to my initial meeting with them, I was pretty deflated. Perfection is subjective- and I'd been looking for my version of a perfect fit for months and hadn't even come close. If I was going to join a gym at this point, I needed some convincing. But not in the typical gym-salesman pitch way. I needed to be bought-in. I needed to see the passion. The knowledge, the dedication, the practicing-what-you-preach. The ability to teach. I don't know maybe I'm a tough sell with unrealistic expectations *shrugs* My meeting went well. Ron was patient. I asked so many questions I made my own self tired. He didn't get tired. All of my reservations were addressed. I was satisfied. By the end of the meeting I could tell, this guy could seriously talk about this stuff all day. Passion: check. The program I selected felt like it would work with my schedule, the price was comfortable, and so far the customer service was on point. Ok...ok...willing to give these guys a chance. What's 9 weeks, am I right? That was in September 2019. It is now February 2020, 5 months later- I'm fully bought in. It did take some time to realize that this was the place for me, so I encourage readers of this review to keep that in mind. From my very beginning the team at Underground Fitness was communicative, invested in my success, flexible, creative, and believed in me more than I did. For those who I've worked with: Ron never blinked an eye when I needed to talk to him about absolutely anything at all (literally anything). Camille comes to my aide with worksheets, resources and meal ideas as I struggle with meeting my macros. She checks in on my off days, finger always on the pulse. She gently pushes me when I'm being a huge baby. She throws fun creative workouts our way, during which I can be observed smiling from ear to ear. They are so fun! The hour is over before I even know it! Daniel challenges every inch of air available in my lungs with creative circuits, helping me learn to use my body as an extension of myself. Teaching me how to stay grounded in my workouts (I can be super ADD). Each of them keeping a critical eye on form and technique. They are patient when I am low energy and have a sad workout. They are excited for me when I make progress. Even though these team members have spent years learning the fitness do's and don'ts for themselves, I never feel anything but encouraged when demonstrating my own lack of knowledge in nutrition and physiology. I can't tell you how many times I got talked off of the cliffs I put myself on. Active listening here folks! Guys, I didn't know what a fitness partnership looked or felt like until I met the U-fit team. You just have to let them be part of your journey, you won't regret it! The End

It showed I lost 5" all around! Say what? Then we went up a notch and in a total of 4 months I lost 15lbs and 18" all around! Yes 18". Now my abs are POPPING! I'm also now wearing a size 2 jean--which I've never been in before. His program is a no nonsense, no fad or silly workout routine. It's a comprehensive program for anyone who is serious about weight loss and getting in shape. It's super simple. Seth is amazing to work with. He is very confident and knowledgeable. He can work through any issues with injury, diet, etc. He guides you through the workouts and encourages you along the way. The accountability alone made a huge difference and kept me consistent even when motivation dipped. And if anyone has an excuse, it's me--I have three kids, one with special needs, a job, and real life happening nonstop--yet this program was still realistic and doable. Beyond the physical changes, my confidence is at an all-time high and I finally feel strong, capable, and proud of my body. If you're on the fence, don't be--this program works, and I'd recommend Seth without hesitation.
