Nice Gym!! I have been a member for over 10 years and enjoy the atmosphere of the gym. The equipment is good but could use a couple of new pieces. The gym is clean and staff is friendly. The men's bathroom has only 1 stall designate for handicapped and large enough to accommodate a Service Dog and/or wheelchair!

This is my favorite Mountainside location! The staff is friendly and the facility is clean. They always have clean towels and antibacterial wipes available.

My kids love going to this location and the girls always remember my kids' names.

I have had a wonderful experience at this gym. The childcare workers are all wonderful and greet my children with such sincerity it makes us all love coming! I've enjoyed every workout class I've tried as well, all the instructors are fun and high energy. The gym and parking lot can get super duper busy so I do recommend going off hours if you can. But overall great experience and enjoy going here!

Audrey who works at the Front Desk at Shea is so welcoming and helpful. It is so nice to have a person that greets you and is interested in you. She is very competent and does an outstanding job at everything she does. Mountainside is lucky to have such an outstanding employee! Thank you!
