So I have been coming to Mountainside for about a year or so. The new one in Desert Ridge in my way home so no excuses to not go, I literally have to drive right by it. My only negative comment of the DR location is parking. If you are going prime time 5pm-6pm be prepared to park in the dirt lot. I have tried many of the classes: spin, yoga,Zumba and all of the instructors are great. Also facility is always clean. Now I also go to the Arrowhead location I have had some great Zumba classes there. They also have a strength class that I do not believe DR has. I appreciate the complimentary towels. I wish they offered more 30 mins spin and also a kettlebell or body pump class. Can't wait to try the Norterra location as well. As you can see I travel and have used many of the facilities even Ocotillo.
