Vegas Yoga (aka Bikram Yoga Las Vegas) stands out from the Strip’s garish, neon tempest as a beacon of calm. Lungs feel as fresh and clean as a newly laundered spearmint leaf, thanks to an energy-efficient HVAC system that emits purified oxygen and tropical temperatures. Wireless sensors monitor humidity and carbon-dioxide levels, keeping yoga students comfortable as they rehearse the 26 hatha poses that foster strength, flexibility, and focus. Besides opening pores and flushing out pent-up toxins, the heat loosens muscles, helping pupils achieve deeper stretches than they might pull off at room temperature. Flotex eco-carpet shoos allergens as it cushions feet with a surface softer than a kitten wearing a velour tracksuit. After class, students can hit the private showers in elegant locker rooms complete with marble counters and a crystal chandelier.
