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. I was one of two newbies today and the instructor personally greeted us; took us into the room early and explained each movement we’d be doing in class. Asked for questions and then put us on reformers near her.
The moody lighting and upbeat music made the Pilates intimidation factor drop dramatically. I’m no ballerina, and the workout, environment, cues and music all felt very ATHLETIC. Loved it - no notes. Coming back for sure. Thank you!

Onyx has quickly become my favorite Pilates studio 🥹 the heated Pilates classes are my new favorite way to workout, it’s honestly so unique and have truly seen a difference. Been coming here for a couple months now and will continue to come daily. The instructors are amazing! The front desk staff are sooo sweet. Cannot recommend enough!

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.

The class formats are well thought out—you can find everything from strength-focused to more cardio-driven options, and the playlists are usually on point (nothing like a good song to push you through those last few reps!). The equipment is in great condition, and having showers available is a huge bonus for anyone heading to work or errands right after.

That said, my biggest con is the layout of the reformers. Depending on your height and where you’re positioned, some movements are hard to do fully without bumping into a wall, a stack of weights, or the person next to you. They also recently got a phone number, which is great because it was a big inconvenience not having one before. Lastly, the credit card fee feels a bit high.

Overall, though, this studio offers amazing workouts, a friendly community, and instructors who truly care. Highly recommend checking it out if you want to be challenged and feel great afterward!

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. They have a few deals, so check the website to confirm before booking.

What to bring:
- Bottle of water
- Grip socks

I love this Pilates studio! This is the first time I’ve ever been excited for a workout. The music and the lights and different themes make you feel like you’re at a party. The workouts are challenging, but the instructors offer modifications for beginners. I’ve had great experiences with all the instructors I’ve tried so far, but Care is my absolute fave! She always has the best playlists.

This was my first class at studio Onyx. I got there early and Elissa was so great; she showed me around the room and explained the reformer. Class was amazing!! The vibes were great!

I'm an experienced classical Pilates person and I found both the equipment and the instruction at this studio to be lacking. The instructor spent the entire class on the machine doing the moves so there was really no supervision of the students and zero form corrections. The setup is designed to cram as many reformers in the space as possible which means you can't see the instructor well depending on your spot in the class. Do not come here as a beginner, and if you're experienced it's not worth your money. There are far better studios in the city.

I recently took my first ever pilates class at this studio and loved it! I had a lot of questions so I showed up a little early before class to get acclimated, but the coach was extremely kind and patient to walk me through it — something I haven't always felt at other gyms when trying something for the first time. It was challenging, but I felt great after and I'm excited to add this into my regular workout routine.

Would highly recommend Onyx!!

The ONYX studio has an amazing vibe, and they always bring the heat with the playlists (love when they play R&B and hip hop)! Working out can be super intimidating, much less something like pilates, so it’s amazing to have a place where you know you’ll be greeted with so much positivity, offered modifications, and helped with corrections as needed through your workout— ONYX really does care about seeing their class members grow. If you can get into one of Liz or Care’s classes, do it- and be prepared to SWEAT!!

The workouts leave me feeling stronger and somehow motivated for my next class. What truly sets this studio apart (outside of the great people I've met) is the music! Music during workouts is so important to me and these instructors have the BEST playlists - truly haven't found a studio with better music or themed classes! Highly recommend!

Came in 1 minute BEFORE the class started and they still wouldn’t let me in when it was 5 degree weather to come there. Waste of time and literally does not align with their policy. If you need people to come 15 minutes before, start the class 15 minutes before. The class hadn't even started when I came in and the front desk girls were super unhelpful. Not coming back here.

Edit: I told the front desk girl this one NOT my first time here. Just first time through a ClassPass account. So that should not affected me being let in. You being defensive in your response and claiming I’m unfairly reviewing a small business instead of taking responsibility is exactly why I’m not retuning. Also please don’t compare yourself to other studios because I’ve had ClassPass for over a year and no other studio has ever turned me away - studios like corepower, yoga box, amplified pilates, etc always allow you to come in right at start time.

I’ve attended this studio a few times and genuinely enjoyed the classes. However, I was recently refused entry for being just three minutes late to a 9 AM class, despite being inside the studio and ready to go at 9:03. I understand the importance of punctuality, but considering the parking challenges in the area and the fact that I’ve seen classes start a few minutes late before, this felt unnecessarily strict. Unfortunately, this experience left a negative impression and makes me reconsider supporting the studio.

I’m really happy I came here since I’m a beginner with Pilates. I was intimidated by Pilates studios, but I broke my ankle 5 months ago so I know Pilates will be good for rehab. It was a challenging class, but the instructor helped us through the movements so I felt comfortable. The reformers are close together. They are facing the instructor so you can see what they are doing. It’s definitely great for strengthening your core, getting better with balance and toning the small muscles we don’t really focus on normally. Im happy I tried Onyx. I will be back!

I can't say enough great things about Onyx — I tried pretty much every pilates class in the River North area and this is the one I decided to get a membership with and I can’t recommend them enough. Onyx helped me follow through on my 2024 new year’s resolution to find a consistent workout routine. (the classes are motivating & gave me a workout I actually looked forward to)!

The instructors at Onyx are incredible — every single one of them is not only fantastic at guiding you through the exercises but also takes the time to offer helpful corrections to improve your form. They do the workout with you, so you're never alone, and their energy makes each class enjoyable and manageable while still pushing you to challenge yourself. Plus, the vibe is super positive and welcoming—there’s zero judgment, which makes it such a great environment to really focus on your fitness goals. The music is great; and they also do themed classes and unique things like reformer pilates by the Lake so there’s also something fun to try out.

The heated studio is plus too — the heat really helps you break a sweat and get the most out of your session. But on days when you’re not feeling like a heated class, there are also non-heated options available.

If you're looking for a place that will motivate you & challenge you (even if you’re a beginner to reformer pilates) — definitely check out Onyx! Can’t thank the folks at Onyx enough for helping me achieve my fitness goals in 2024 and I’m excited to watch their business continue to grow :)

Coach Care gave us a good workout that made me feel strong and balanced. I lift weights four to five times a week, so the Onyx method complements my workout regimen. I love the stability and core workout that she applied to the reformer, and the lower body part of the workout had me shaking. Overall, I love the way it built my muscle endurance, stability, and core, leaving me feeling strong and balanced.

I can’t say enough good things about this studio. It’s clean, the instructors are supportive and kind yet want to challenge you. It’s not pretentious or judgmental like a lot of Pilates studios tend to be, and I’ve been to just about every studio in the city. I absolutely LOVE the heated classes, but be warned they can get quite hot (the hotter the better in my opinion). The mat and reformer classes are both excellent. It’s truly a full body workout where I get to check out of reality for 50-minutes and just sweat it out. Absolutely love it here.
