Yoga emphasizes seamless transition between poses, a skill set adopted by the Navy to teach cursive flag semaphore to its sailors. Spell out serene stances with today's Groupon: for $35, you get one month of unlimited yoga (up to a $130 value) or a 10-class punch card (up to a $120 value) at Stray Dog Yoga Studio in Wexford.

The experienced instructors at Stray Dog Yoga Studio shepherd body benders through a series of Vinyasa movements executed in a heated room. Pupils stretch and sweat their way through the flow, which unites movement with breath the way a magnet unites Dad's finger paintings with the refrigerator door. Each class challenges partakers to push their bodies, find the limits of their flexibility, and discover a sense of peace within themselves. Stretching students of all levels can participate, as modifications for difficult poses allow beginners to follow along and work toward improvement.

A lobby accoutered with Stray Dog apparel and yoga mats welcomes students, who store their shoes or stilts in cubbyholes before joining the class. Natural light floods into the studio via tall windows, illuminating the floors and the students that stretch out across their mats.
