I visit this location frequently as its close to work and vist the location in Rockwall as its close to home. This gym is on the second floor in Highland Village shopping center.
They have a wide assortment of machines, probably more than 65 and about a dozen treadmills. The trainers are all certified professionals and offer great programs and support.
The men's locker room has a few showers and enough lockers, I've never had a problem with crowding, but I do go at lunch. I'm not sure what the mornings are like.
Memberships cost me $300 start up and about $65 a month for dues. If you would like a smaller gym chain without all of the hassle of the larger gyms (waiting for machines, etc.) then check out Larry North's.
