Recent studies show that people who dance tend to possess above-average strength, endurance, and flexibility, as well as significantly less risk of getting served. Hone this vital skill with today’s Groupon: for $22, you get five dance classes at First Position Dance Arts (a $75 value). The studio is located in Ardmore, 8 miles northwest of Philadelphia by brisé volé.

Seven days a week, First Position Dance Arts offers a Swan Lake's worth of dance classes for both adults and children. Under the tutelage of the studio's graceful guides, students will take on the fearsome foes of rhythm, balance, and poise through a well-coordinated attack of box steps, chasses, and pops/locks. Adult class options include ballet, modern/jazz, hip-hop, choreography, and even a dance history and culture class (click here to read descriptions). This year, First Position Dance Arts is also offering Zumba aerobics courses, which forge fitness through music based on salsa, merengue, calypso, and other styles.

First Position has been molding movers and shimmiers in Delaware County for 20 years. Even if you don't dream of pirouetting in Paris or axel-jumping in Alaska, dance classes offer bodacious benefits, including an improved cardiovascular system, potential weight loss, and a good icebreaker should you happen to meet the ghost of Martha Graham. Call ahead to schedule classes; no prior dancing experience is necessary.
