From the reviews

Hotworx has changed my life! I have never before joined a "gym" and this isn't a gym! It is a new lifestyle for me. The infrared saunas have helped in so many ways, the most noticeably being my skin! So smooth. I am toning up muscles I didn't know I had. The sweat. Let's talk about the sweat!

★★★★★ — Gina, Oct 2022

I joined hot worx about two months ago. Part of it is that I'm autistic and the tiny enclosed boxes and chance for privacy really help me stick to my workouts when I otherwise can't handle overstimulation from a normal gym.

★★★★★ — Eva, Nov 2025

Seriously one of the best workouts ever. I did the research and the benefits described is true. Can be for anyone, but for joint issues this is a lifesaver. Don't let the heat steer you away. The classes are short low or no impact and the results last for pain relief. Staff are dedicated, knowledgeable and amazing.

★★★★★ — Linda, Dec 2021

HOTWORX has been a great addition to my workout routine. I have found improvements in so many aspects of my fitness. My endurance has unexpectedly improved. My flexibility is much better and any of the pain issues associated with my morning workout have disappeared.

Your first hot yoga class at HOTWORX - Northborough, MA

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.
