People holding yoga poses typically seek self-discipline and control, whereas those holding yoga posters just want Sting's autograph. Find peace while standing still with today's Groupon: for $37, you get five introductory (Level 1) yoga classes at Stillwater Yoga's Midtown location (a $75 total value).

Under the tutelage of Stillwater's expert instructors, fledgling yogis begin to master the basics of Iyengar yoga in group sessions that bolster flexibility, balance, and overall well-being. On a mat-covered wooden floor populated by up to a dozen classmates, pupils learn critical yoga techniques such as proper breathing, maintaining correct posture, and ignoring the annoying calls of telemarketers yelling through the windows. Early training involves a preponderance of standing asanas (poses) that hone muscles as well as toe-touching skills, and all Iyengar movements stress the importance of bodily alignment. During sessions, sutra squires also put to use yoga props—an innovation unique to Iyengar yoga—such as blankets, blocks, straps, and pillows.

Patrons should wear nonrestrictive clothing suited for athletic activity (changing rooms are available on-site) and leave behind perfume, heavy jewelry, snow-covered mittens, and all footwear. Trainees are also encouraged to come to class on a light or empty stomach in order to more comfortably complete stretches. Check the schedule to confirm class times, classes run July 5 through November 30.
