An addicting workout sounds like an oxymoron on par with fat-free ice cream, but it's a definite possibility with today's deal from CrossFit Paradox: Get two weeks of unlimited classes for $29 at this brand-new Lombard gym (regularly $85). Celebrating its grand opening on June 1, CrossFit Paradox has already created a lot of buzz with its spacious, expertly equipped facility off South Finley Road. These multidimensional classes aim to improve your endurance, stamina, power, speed, flexibility, and more -- all by taking cues from a variety of fitness realms like gymnastics, Olympic weightlifting, and cardio drills. These high-intensity, hour-long sessions are available throughout the day on weekdays and on Saturday mornings -- meaning a convenient fitness regime is no longer a paradox, either.Want more?
