Breathe Pilates and Fitness Studio

Suspended about 2 feet off the floor, a student sinks into the bend of a camel pose. The class is called aerial yoga, and instead of achieving proper alignment through effort on the floor, it asks students to relax into each posture while hanging from silk hammocks. Specialty classes such as this join pole fitness and TRX-suspension training as unique outgrowths of a fitness practice focused on Pilates and yoga. Instructors prioritize individual attention throughout each session, helping each student develop bodily awareness and posture sound enough to be a convincing yardstick for Halloween. Beyond classes, the studio's services extend to teacher training and spa treatments including massage therapy.
