Without Pilates training, people would only hold the limbo pole when they needed a low-lying fence, low-difficulty hurtle, or high-maintenance clothing rack. Give the stretchy stick a purpose with today's Groupon: for $40, you get three mat classes and one private lesson at 6 Keys Pilates (up to a $110 value).

At 6 Keys Pilates, dedicated instructors guide students through individual and group sessions designed to increase flexibility and boost overall physical wellness. During mat classes, limber students enjoy the simplistic comforts of both small class sizes (typically less than five students per class) and stripped-down equipment (a mat, a motivating voice, and an obliging muscular frame). Private lessons are matched in terms of enthusiasm, and they feature the additional perks of personalized attention and a variety of resistance-driven equipment. Classes are available throughout the week in both the morning and evening hours. For complete information, check the class schedule online.
