It looked similar to CrossFit to me. I'm so glad I pushed through that and gave it a shot. It ended up becoming my home gym and the place that fostered me regaining my strength and confidence. This place is always clean. The music is energizing. The workouts are programmed very well. Half the days are cardio, the other half resistance/weights. You get what you put in. But I can't get a better workout in 45 minutes anywhere else. Also, there is always a great stretch offered after class, which I don't recommend skipping! The coaches deserve their own very special acknowledgment. Management does a great job hiring qualified trainers, who also have great people skills. They always take the time to welcome you and do a great job explaining/offering a demo of the workout. And you can always count on them to keep an eye on your form and keep you motivated during the workout. This place is a gem in our community. I look forward to hitting 100 workouts! And hope to see you there!

It's a little further away from home for me compared to some other options, but I'm sure I'll be back to drop-in for more classes!

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

Has been quite a while since I have done any type of weight training, and finally made the decision that it was time to get back to a gym. Glad I made Underground Fitness my choice.

It was our first time here and honestly, we were super nervous and intimidated walking in, but from…read morethe moment we stepped through the doors, we felt totally at ease. The guy at the front desk was incredibly friendly and helped us check in without any stress. We took the TriCore Fire class with Mackenzie, and she was amazing! She took the time to explain the reformers (which we had never used before) and guided us through everything so we didn't feel lost. There was also another instructor taking the class with us, and she was just as sweet and supportive. Everyone ,from staff to instructors , made us feel welcome, supported, and empowered. It was a genuinely fun and challenging workout -- the kind that makes you sweat but still enjoy every second. I'm already planning to come back for another class. I will say it is smaller than expected, and there were about nine people in our class, which we didn't mind. I can't recommend TriCore enough. You'll leave feeling stronger, more confident, and glad you gave it a shot!

No question is too stupid to ask and the information and experience I've gained from working out with the coaches at Trifit is priceless.
