Since the rise of the Internet, people have struggled to tear their now-useless phone books in half. Bulk up to succeed where others have failed with today’s Groupon to Advocate Condell Centre Club, with locations in Gurnee and Libertyville. Choose between the following options:

• For $18, you get three guest passes (a $36 value).
• For $30, you get a one-month membership (a $90 value).

The facilities at both Advocate Condell Centre Club locations cover more than 70,000 square feet and sate fitness seekers with group classes, muscle-building machines, and a wealth of post-workout amenities. Work up a social sweat in group fitness classes, including high-energy spinning, or dabble in resistance training with the club’s stock of weightlifting apparatuses. The orange reptilian skin of soaring basketballs deflects off backboards in the regulation basketball court, and soft orbs bounce around the clubs’ racquetball courts. Exercisers can sidestroke in the five-lane, 25-meter lap-and-exercise pool or hit the proverbial pavement on a 0.1-mile cushioned running track.

Post-sweat, relax in a sauna, steam room, or whirlpool without dampening personal belongings, which can be conveniently stashed in fully appointed locker rooms. The center's free supervised childcare keeps kids from investing heavily in pork bellies while parents get their fitness fix.
