If you live in Evanston and you belong to a gym, it's probably the Evanston Athletic Club or the YMCA. The EAC really is a nice choice though. They've got your typical gym equipment, and it's all in good condition and fairly up-to-date. They also have steam rooms and saunas, a pool, and free classes open to members. What's a little more unique about this fitness center is that it has an indoor rock climbing wall. Pretty neat!
I like it because it's conveniently located, isn't full of scary jocks, and yet has all the equipment and facilities you need to keep in shape or bulk up.
