HOTWORX Boulder is a 24-hour infrared fitness studio where members engage in virtually instructed workouts within private infrared sauna rooms. The core experience centers on the infrared sauna environment, which members can personalize by adjusting the temperature to their preference, with a default setting around 125 degrees. The infrared heat is noted for its effective therapy, contributing to perceived benefits such as improved sleep, pain relief, and a more efficient workout. The sauna facilities are consistently described as impeccably clean and well-kept. Each private sauna room features a television screen that airs the scheduled class, allowing for a focused, individual workout session. This gym offers a wide variety of class options, including High-Intensity Interval Training, Hot Pilates, Hot Yoga, Hot Barre, Hot Core, and Hot Cycle, with new classes refreshing approximately monthly. Class sizes are limited to three people per sauna to ensure ample space. Members highly value the 24/7 access and flexible schedule, enabled by phone-based entry after joining. The atmosphere is welcoming and chill, with friendly and knowledgeable staff. The gym also provides a functional exercise area and retail offerings like gear, lotions, and supplements. Some members note the television placement can be awkward to view, and certain classes may not include traditional equipment like a barre, though personal music devices are permitted.
