From the reviews

I just joined a few weeks ago. I love the access to working out 24 hours a day. Every 15 minutes there’s an option for a class! The infrared heat adds an addictive challenge and I feel like I get 75-minutes worth of workout in just 45. The space and equipment is impeccably clean.

★★★★★ — Cali, Nov 2022

Love this place! Staff is so friendly, facilities are super clean, and I love that I can get a fast and effective workout whenever I want. So much variety I can always find the right class to match my energy level and what I need that day.

★★★★★ — Emily, Sep 2022

This place is amazing! It’s one of the first gyms that I don’t have to talk myself into going to, I actually want to go! For someone who is introverted and enjoys some alone time, this place is a dream! You can schedule your sessions in the app and generally have a sauna to yourself 🙌🏻.

★★★★★ — Christina, Nov 2022

When I joined HOTWORX Boulder I had no idea that I would absolutely fall in love with this place. The HEAT is extraordinary and the variety of sessions offer an overall body workout. The staff and owner are amazing and responsive. The studio is spotless and the opportunity to workout 24/7 really works for me.

Your first hot yoga class at HOTWORX - Boulder, CO

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.
