Ever since I've started going to this fabulous gym I have enjoyed every single second of it, the machines, the service (especially from Justin the GOAT), and those amazing high quality smoothies. I've been going here for 4 months and I won't stop coming. Absolutely fantastic gym.

Justin Block is the whole reason I attend Mountainside fitness.....he makes unreal smoothies.....but more importantly is an incredible employee and worker. Mountainside should be thrilled to have him as part of their team.

Mountainside Desert Ridge is honestly the best gym ever. I look forward to coming here every single day because the energy is always so good and the people make it feel like a second home.

The staff, the environment, and the community here are unmatched. I can't imagine starting my day anywhere else!

I've been going to this gym for a while now, and I couldn't be happier! The equipment is always clean and well-maintained, and there's a great variety for both strength training and cardio.
