Hotworx - Chattanooga, TN - Downtown

This 24-hour infrared fitness studio provides members with private, virtually instructed infrared sauna workouts. The infrared sauna sessions are central to the experience, with gym members reporting a profound detox feeling and significant sweating. The private sauna rooms allow for solitary workouts, which many find less daunting than a traditional gym environment. Members note the saunas are typically clean and prepared for use, though some have reported occasional inconsistencies in cleanliness and preheating reliability. A variety of 15-minute High-Intensity Interval Training and 30-minute isometric workouts, including Hot Pilates, Hot Yoga, Hot Barre, Hot Core, Hot Cycle, and Hot Blast, are conducted within the heated sauna environment. The combination of infrared heat and movement is credited by members for delivering more effective workouts in less time, leading to noticeable toning and strength results.

The gym offers extensive flexibility with 24/7 access and a wide variety of recorded instructor classes that change quarterly to prevent boredom. The staff, particularly noted members Josh, Rey, and Regan, are frequently described as welcoming, fun, and passionate, often knowing members by name. Amenities include towels and toiletries for showering. Some members have experienced issues with the class scheduling app, door access, a broken sauna volume knob affecting audio, and the downtown parking situation, though the gym provides a QR code for parking garage validation.
