The gym is always clean and the people, at the desk and other gym-goers, are always super nice. I love coming here every morning for my workouts! This gym is a great size and has tons of machines. I'm almost never waiting for my turn on something :)

This review is for instructor Jill Cathbertson. She is very good at what she does as instructor. She enjoys her class and understand her students in the classroom. This is for silver sneaker class. Thank you Jill. I really enjoy your class.

Been coming here for the better part of 3 years. Been to a lot of gyms in my day but MSF tops them all. The instructors are awesome, consistently here, and very personable. Hailey, Autumn, Pam, and Stephanie are my personal faves. I also love that you don't typically have to wait for machines... it's rare. There's plenty of machines for all the muscle groups. Huge gym, great staff, clean, good protein shakes too.

My favorite gym! Been going for 6 years and have no plans to stop. I love the childcare, the machines and amenities that are all included in the monthly membership. I have tried other gyms but didn't stay because they didn't even offer towels and were always so busy I couldn't get on the machines. I definitely recommend mountainside if you are looking for a place to stay fit.

I have been going to Mountainside for years. After trying multiple others, it is the best quality for the price. Always very clean and I rarely wait on machines.

Members service does not properly educate you on what is needed to cancel membership with active and fit and refusing to refund my money for the daycare they continue to charge me even though I don't have a active membership
