Formerly known as Bikram Yoga Bethesda, Pure Om Hot Yoga's studio sports a steely gray palette, exposed ducts, and bright, natural lighting that provide a cool counterpoint to the heated intensity of its Bikram yoga classes. The new owner, Siri Om, brings extensive experience to her teaching style, as she began studying Bikram yoga in 1994 at the Yoga College of India in LA, and has been teaching Bikram yoga worldwide since 2001. Though rigorous with its balmy heat and strict 26-posture series, the 90-minute classes are open to students of all experience levels and are taught by a team of Bikram-certified instructors. The 4,700-square-foot facility boasts not just an expansive practice space outfitted with a brand new, medical-grade linoleum floor and a natural-gas-fired heating system but also shower and locker-room amenities that make changing back into street clothes or cartoon-character costumes comfortable and efficient.
