Novelty shirts airbrushed with bikini-clad bodies provide the convincing, if temporary, illusion of fitness. Find a more permanent fitness solution with today's Groupon: for $20, you get a 10-day pass and two personal training sessions at O2 Fitness (a $131 value). This Groupon is good for full access at all eight locations in the Triangle area (see the sidebar on the right for a full list of locations).

Sweat will bead upon the brow just looking at the list of more than 50 group classes offered weekly. O2 gives its members options ranging from the intense BodyCombat to the ragingly soothing Hatha yoga. Aqua classes tone members' muscles through the power of foam noodles, and Step and Sculpt offers a cardio-pumping combo of weight training and clay modeling. In your two personal training sessions, regardless of your style or skill level, O2's skilled trainers will bring you the spirit and guidance of an owl without the uncomfortable panoramic head swivel. If you decide to join the fitness club after your 10 days are up, O2 Fitness will also waive the $99 enrollment fee.

The welcoming staff at O2 Fitness designed its hall of fitness to make you feel welcome and comfortable. When you hand them a sopping, stinky towel, they'll say, "Thanks," and nail it up on their trophy wall, and when you emerge from the sauna, you'll be swarmed by a hired staff of children screaming for autographs.
