Hotworx - Vienna/Merrifield

Workouts inside the patented infrared saunas split between 30-minute isometric sessions—covering Hot Yoga, Hot Pilates, Hot Core, and Hot Stretch—and compact 15-minute HIIT workouts such as Hot Cycle, Hot Thunder, and Hot Blast. For supplemental training, the studio provides the FX Zone, an area stocked with free weights, resistance bands, and ropes for pre- or post-workout routines. The facility operates 24 hours a day.
