Brrrn is the first cool temperature boutique fitness experience! Brrrn offers three 50-minute group fitness classes that operate in 50°F: SLIDE, HIT, and HIT + SLIDE. Their research-driven concept is disrupting the fitness landscape by pairing the benefits of routine cool temperature exposure (called mild cold stress) with exercise (called environmental conditioning) to optimize the fitness experience—as well as provide other health benefits, such as burning fat and more calories than in ambient or hotter environments. They also offer a communal infrared sauna experience.
