Getting in shape, much like speed-reading Russian literature, requires concentration and the strength to forge ahead through painful, protracted inner monologues. Forge ahead toward fitness with today’s Groupon: for $19, you get 10 group fitness classes (a $50 value) at Fitworks in Beavercreek.

Fitworks is home to a dedicated cadre of certified muscle architects who guide eager physiques through intense, small group workouts. Peruse the schedule before sampling a tension-undoing yoga class or a weekend-morning muscle-pump session, ideal for prepping for an underwater bench-press that will determine the office's next round of promotions. One-hour Zumba classes harness the rhythmic power of merengue, conga, belly dancing, and more to kill calories while resuscitating sleepy toes. After classes, students can freshen up or flex unused singing muscles in Fitworks' shower facilities.
