Strengthen yourself while remaining physically and emotionally stable with today's Groupon: for $55, you get nine Pilates mat classes at Studio Body Logic (a $162 value). This Groupon can be redeemed at Studio Body Logic's studios in Arlington or Alexandria.

Studio Body Logic accepts no fitness forgery in its offering of authentic and unchanged Pilates, the core-strengthening conditioning regimen created by Joseph Pilates in the 1920s. Build strength, elongate muscles, and improve flexibility with nine Pilates mat classes ($18 each). Over the course of this exercise ennead, students of all levels of experience can immerse themselves in the full-body workout pioneered by Pilates, taming torso tigers, straightening up spinal sloths, and pinning down postural platypuses. The nine Pilates mat classes offered in this deal take place during Studio Body Logic's summer session, from the week of July 5 through the week of August 30. Classes are offered throughout the week, starting as early as 6:15 a.m. and as late as 8:15 p.m.—perfect for the many Studio Body Logic students making commutes from Peru or parallel dimensions.

Studio Body Logic, one of Northern Virginia's first authentic Pilates studios, is led by founder/director Karen Garcia, a renowned Pilates expert with the rare distinction of having studied under one of Joseph Pilates' protégées. As such, she demands the same commitment to Pilates' original teachings from her own studio's instructors. All of Studio Body Logic's Pilates pilots are fully trained in authentic Pilates, having completed at least 800 hours, or approximately 2,181 episodes of Mama's Family, of intensive training. Free yourself from a cage of stiffness and sloppy workouts with nine Pilates mat classes from Studio Body Logic.
