Crunch - Mount Prospect at 225 West Rand Road, Mount Prospect, Illinois.

It's difficult to find a gym that's reasonably priced that has all the equipment and classes you want. This one is definitely it!
There's a well-stocked weight section, plenty of cardio machines and a turfed area for body-weight training and calisthenics. There's no pool. They also offer several options with memberships which is a BIG plus. I originally signed up for the basic membership (access to gym, no classes or tanning) and upgraded a few months later. The upgrade was painless and my change-of-membership fee was waived!

My only "complaint" is that the spin classes fill up quickly on weekends. Make sure to get there early!
