From the reviews

Would recommend. I enjoyed my first ever Heated Pilates (w/reformer) class. The heat wasn't unbearable, but you'll definitely sweat. As a first-timer, it is hard to see the moves & hear the instructor. However, I really enjoyed the class & signed up for a 2nd one.

★★★★☆ — Kendra, May 2025

I discoverd Onyx when I was visiting Chicago. River North is in a great location and I really love the heated classes (the non-heated class is also great!)! The staff is also really nice and the studio is beautiful. Showers, lockers, water fountain/filler, cold towels, great instructors.

★★★★★ — Eunhea, Jul 2025

I absolutely love coming to this studio! The instructors each bring their own style, but they’re all knowledgeable, encouraging, and great at offering modifications so everyone can get the most out of class.

★★★★☆ — Sierra, Aug 2025

I came here for the first time this morning and was instantly welcomed with smiles and greetings. As a fitness professional myself, I admit I have a higher standard than most when paying for fitness classes. The staff knocked it out of the park.

Your first hot yoga class at ONYX RIVER NORTH

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.
