My only complaint is that they don't have a sauna (only a steam room)... but with how clean and uncrowded this gym is, it's definitely not going to deter me from coming here. They also don't offer a lot of classes but that makes sense considering the fact that it isn't a busy location. I have been here at all times of the day (except early morning... which I have heard is the busiest) but the staff is always friendly, locker rooms and equipment clean and I typically can get my full workout in without having to wait for any machinery. It is my favorite Mountainside location for that reason alone... I joined because the Arrowhead location is less than a mile from my office but it is extremely busy after work but if I don't manage to get a workout in before work or during lunch, it's super crowded so it's great to have this location closer to home.
Side note... no childcare (which I think is one of the reasons it isn't busy and isn't a problem for me since I don't use the childcare)
