HOTWORX studios are fitness centers built around virtually instructed, infrared sauna workouts. Each studio features small, enclosed “HOT” rooms heated with infrared energy—typically around 120–130°F—to promote deeper muscle engagement, increased calorie burn, and faster recovery.

Inside each sauna-style room, members follow a variety of isometric and high-intensity interval training (HIIT) sessions led by virtual instructors on large digital screens. Popular workouts include:

Hot Yoga & Hot Pilates
Hot Cycle & Hot Blast (HIIT cycle and elliptical)
Hot Iso (isometric strength sessions)
Hot Buns, Hot Core, Hot Bands, and more

Classes are offered in efficient 15- and 30-minute formats, making them easy to stack or fit into a busy schedule. HOTWORX studios typically operate 24/7, allowing members to book sessions through the app and access the studio at any time.

This Ann Arbor HOTWORX studio features 7 infrared workout saunas and a dedicated FX Zone, a functional training area where patrons can use free weights, resistance tools, and other equipment to complete workouts outside of the saunas. This gives members added flexibility to customize their fitness routine—combining heat-driven sessions with traditional strength and conditioning.

HOTWORX emphasizes benefits such as:

Increased calorie burn through its 3D Training method (heat + infrared energy + exercise)
Improved circulation and detoxification
Greater flexibility and mobility
A private, self-paced workout environment

Overall, the HOTWORX Ann Arbor studio delivers a convenient, heat-intensified, and highly customizable fitness experience suitable for all schedules and fitness levels.
