Chiseled abs play a vital role in our daily lives, whether we're using them to sustain high notes during arias, cushion incoming cannonballs, or make action figures feel envy. Keep your torso taut and limbs limber with today's Groupon: for $10, you get four classes (a $60 value) at Urban Pilates in Northeast Portland.

The certified instructors at Urban Pilates teach an adaptive curriculum of more than 20 strength, flexibility, and cardio group classes in a functional fitness suite of floor-to-ceiling windows, shock-absorbing floors, and exposed pipes. All levels of core-carvers can boost abdominal strength, stability, and the ability to accurately throw darts with one hand while bobbling a hot potato with the other in a 50-minute Mat Class. Otherwise, taffy-stretch your endurance with a 45-minute Cardio Pump class consisting of five to seven workout stations, or use resistance bands to tone torsos with a one-hour Body Sculpting class. Urban Pilates also offers three varieties of yoga and a M.E.L.T. Method class, a healing regimen that reduces muscle tension and joint pain while teaching you how to make s'mores with your mind.
