I just became a member a couple weeks ago, i researched the heck out of fitness centers in my area. Mountainside is by far the cleanest of the bunch. Their cardio equipment is great, if there is a broken machine it gets repaired quickly. The weights area has machines that are perfect for the novice like myself.
The staff is very nice and helpful if needed, but they are not pushy like other places i have been to.
Needless to say i am very happy with my choice to become a member.
