From the reviews

HOTWORX has been a game-changer for my fitness routine! The infrared heat combined with effective workouts makes each session feel incredibly productive. The benefits of infared sauna are so amazing, google them! I also love the 24/7 access, allowing me to fit workouts into my schedule whenever it’s convenient.

Have you heard about the benefits of Infrared LightTechnology in detoxing your body? What about how heat while working out can help melt away fat faster? What if I told you there was a place right here in O’Fallon where you could do both and earn the burn 🔥 with every work out?

★★★★★ — Market, Sep 2025

Hotworx is your answer when searching for the Right Gym for you. It offers 24/7 access with unique infrared sauna therapy that is beneficial on so many levels. Working out has always been a love hate relationship but from my personal experience the love out measures the hate :) Did I mention the staff is exceptional…

★★★★★ — Barb, Jan 2025

I took my first class at Hotworx and was very happy with the workout. It was more than yoga, this was so effective on my core and balance. As a boxer who works out 5 times a week, it still challenged and I walked away drenched in sweat. Highly recommend! Friendly staff & great atmosphere all around. Thanks again!

Your first hot yoga class at HOTWORX - O'Fallon, MO

Nervous about your first hot class? Almost everyone is, and a good studio expects beginners to walk in the door. Here's what to know. What to expect: the room is heated, so it feels intense for the first few minutes — rest in child's pose any time you need to, no one will bat an eye. Hydrate: drink water through the day before class, not just as you arrive, and bring a bottle. What to bring: a mat and towel, water, and a change of clothes; wear something light you don't mind sweating through, and skip a heavy meal in the couple of hours beforehand. Arrive 10–15 minutes early to sign in and set up. It gets easier fast — most people say their third class feels completely different from their first.

Heat and intense exercise aren't right for everyone — if you're pregnant or have heart, blood-pressure, or other health concerns, check with a doctor before your first hot class.
