Legs and torsos originally communicated through a series of high-kicks and shimmies, until mouths and brains trash-talked them into silence. Let your limbs speak freely with today's Groupon: for $19, you get one month of classes at Dance Trance (a $125 value).

Founded 16 years ago by Jay and Beth Handline, Dance Trance constructs an upbeat fitness regimen that doesn't require reenacting historic dance battles such as the Hoedown of Antietam to burn calories. During hour-long classes, students are schooled in four to five dance routines for an invigorating workout appropriate for all ages and ability levels. Each fitness-driven session is different, keeping students on their toes with popular music, lighting effects, and diverse choreography. To keep up with new music and dance trends, exercises are choreographed on a quarterly basis; they incorporate jazz, funk, hip-hop, Latin, and Uncle Steve's best wedding-reception moves, plucked from the idea nests of Dance Trance choreographers across the country. Gym or aerobic shoes are required for class; the smoother the sole, the better.
