A well-stoked bonfire tops 2,000 degrees Fahrenheit. Bonfire Hot Yoga, by comparison, heats up to a comparatively cozy 105. After 90 minutes of Bikram yoga, however, the studio becomes sweltering. And it's all by design. Bikram—the primary form of yoga practiced at Bonfire—guides participants through a flow of 26 postures and 2 breathing exercises. This carefully ordered regimen stimulates the organs, glands, and nerves while replenishing the entire body with oxygen. Heat enhances the practice by helping participants stretch deeper into each pose. At the same time, it ramps up metabolism and spurs sweating to facilitate the elimination of toxins. For those looking for a little less heat, Yin Yoga, Vinyasa Yoga, Gentle Yoga classes are also available.
