I absolutely love this gym! The equipment is nice and I really enjoy the cardio section. The staff is kind and caring. Faith has shown me around and has helped me tremendously with form. I would highly recommend this gym.

This gym is amazing! My wife joined and I’ve been coming as a guest and it’s the best gym I’ve been too! Staff are friendly and attentive, the place is clean and functional and filled with cutting edge equipment and services and her personal trainer Lia is the best!

Ever since I saw the "coming soon" sign for the new Mountainside Fitness at Gantzel and Combs, I have been anxiously awaiting its opening. It has not disappointed.
My husband and I have been training at the QC Marketplace location for nearly two years. We've loved it and still do, but this new location blows me away. Not only is it gorgeous, it's huge with exciting classes, amazing equipment, and an awesome staff. More specifically, I am super excited that Greg Fisher was promoted to this new location. Greg's friendliness, encouragement, and leadership is among the very best. I'm happy that my husband and I still get to see and interact with him. His leadership in the fitness realm is unmatched. Looking forward to continuing my workouts at this beautiful new location!

My wife and I are so excited about the new Mountainside Fitness near us on Combs. The new facility is beautiful. What a great environment to work out in! I am especially grateful that Greg Fisher was promoted to the new gym from the QC Marketplace location where we met Greg. Greg's advice has been instrumental in taking my fitness to the next level. The rest of the staff is friendly and helpful too. The place is shiny clean and the equipment is top-notch.
