Great place. Always happy to answer questions and assist with a workout, but never overly crowded like most gyms. Looking at you old x sports.

As a long time member I’ve appreciated the coaching , responsiveness and quality of the facility. Everything is top notch and they consistently looking for ways to improve. Feedback is welcome and there’s something for everyone from elite athletes to beginners.

Recently I asked for a new piece of equipment and it was immediately purchased which was great. This is what makes this place a wonderful start my day.

The work outs are challenging (same level as the ones posted on the CrossFit home page). Everyone is really friendly, the equipment is top notch and the staff keeps the gym clean. The introductory rate is extremely reasonable, so you have nothing to lose by giving it a try. I’m really enjoying my time here.

It is a dynamic gym with a good vibe, the staff is very friendly and it has a community feeling. The workouts are intense but adjusted to your strength level. The coaches are very much into your movements, correcting you to help you to get the best shape. They are hot strong, and very knowledgeable. Joe the manager is not only in a perfect shape but also a Physical Therapist. I feel very safe working out in a place like this.

I love this gym and community and everyone is friendly and encouraging. Josh is the best trainer and meets everyone where they are with their abilities. His workouts are challenging and he is always switching things up- I don’t think I’ve ever done the same workout twice in the few years I’ve been doing his daily 6:15 am classes. Above all, he is very kind and thoughtful to his students. With his support, I have challenged myself beyond what I imagined I could do.

Love the inclusive community and challenging (but accessible) workouts at RxFitness. Josh is an incredible trainer and Joe and Dennis are so helpful and accommodating when it comes to membership and gym questions. So glad this place is in the neighborhood!

I started my RX journey with Josh in his 6:15 Pulse class, and it’s been the best way to kick off my mornings. The class challenges me in all the right ways, enough to push me, but never to the point where I don’t want to come back. It’s fun, energizing, and motivating.

Josh is extremely knowledgeable and it shows in every workout. He designs classes that are beginner-friendly yet still dynamic and effective, making sure everyone feels included while also progressing. Beyond just training, he takes the time to get to know you, remembers the details of what’s going on in your life, and encourages you to reach your goals inside and outside the gym. He’s a genuine coach who truly cares.

The RX community makes it all even better. It’s welcoming, uplifting, and so close-knit, unlike any other gym I’ve ever been part of. Everyone supports each other, celebrates wins, and creates such a positive environment that you actually look forward to showing up.

RX isn’t just a gym, it’s a family. And Josh’s expertise, energy, and authenticity set the tone for that experience.

I’ve been a member at RX Fitness for over three years now, and I can honestly say it’s one of the best gyms around. The coaching staff is incredible — knowledgeable, motivating, and always willing to help you push your limits safely and effectively. The environment strikes the perfect balance between competitive and welcoming — everyone pushes each other to get better, but there’s a real sense of community and support. Whether you’re new to fitness or have years of experience, RX Fitness is an amazing place to train and grow. Highly recommend!

I wanted to get in great shape before a hip surgery and I'm SO glad I came to this gym! One of the best gyms I have ever been to. They have a Physical Therapist on staff that helped me physically prep for surgery, Personal Trainers to help you get to where you want to be, and classes are top notch! Will be returning as soon as I'm recovered:) Check it out!!!

Rx Fitness Review
I can’t say enough good things about Rx Fitness! The coaching here is absolutely top-notch. I came in with a strong dislike for Olympic lifts, but their specialized classes focusing on technique, combined with targeted warm-ups before workouts, completely changed my perspective. I’ve gone from struggling with a 35# bar for snatches to confidently snatching 95# with solid form—an achievement I never thought possible! The coaches broke down exactly what I needed to work on, tailoring their guidance to my specific needs, which made all the difference.
Split jerks? Don’t even get me started—thanks to the coaches’ personalized feedback, I’ve developed a love for these lifts too! At 60 years old, modifications are crucial for me, and Rx Fitness excels here. The coaches are incredibly attentive, ensuring every workout is adapted to my abilities while still pushing me to improve. If you’re looking for a gym with exceptional coaching, a focus on technique, and a welcoming environment that meets you where you’re at, Rx Fitness is the place to go. Highly recommend!

Joining this place has honestly been one of the best decisions I’ve made. From day one, I felt so welcomed — the community is amazing and the energy is super motivating. The coaches really take the time to help you improve your technique and push your limits.
I’ve seen such a big difference in my strength, endurance, and overall confidence. If you’re looking for a place that truly helps you become your best self, this is it! 🙌

CrossFit Severance is absolutely amazing! I came in with no prior CrossFit experience, and the trainers were incredible – they made everything so much fun and completely non-intimidating. A special shout-out to Dennis Hennessey for creating such a fantastic place, and to coaches Sara, Manny, and David for being so awesome. The community here is also fantastic, super welcoming and supportive. Highly recommend!

I love this spot! It's a clean, inviting space, and everyone here is great to work with. Dennis, Madeline, Katie, Joe, and Jess make the experience fun, and are very knowledgeable about fitness.

If you're looking for a gym with a bunch of machines....this ain't it. Go to Xsport for that BS. This place is all about functional fitness with actual weights. I've been training with Dennis for a couple of years now, and I can see and feel the results. They also offer a variety of classes throughout the day, so you can choose your own adventure. Check this spot out!

My nephew was visiting me during his recent holiday break and wanted to work out. My wonderful neighbor connected me to Dennis (owner of CrossFit Severance). Dennis was super helpful and accommodating for the few weeks that my nephew was in town. I am not a member but I would definitely join if I didn't already have a membership elsewhere. I observed the classes and they look high energy and incredibly motivating. Go check them out!

I bought a Groupon to visit this facility. But they offer a free class so I wanted to try it before fully committing to a membership in the Groupon. Dennis a manager redeemed the Groupon without my permission and stated that they do this to get you to schedule when you want the membership to start. I asked him to undo it as I had not made up my mind yet and he was unbelievably rude and hung up. The free class itself was very nice, a little tough on you if you’re a beginner. But I wouldn’t be interested in going back there simply off this experience alone, even after he redeemed it. The response to this review says it all… And he didn’t refund anything, he tried to keep the money but I had already spoken to Groupon.

RX Fitness-Cross Fit Severance is a great place to work out. Dennis, the owner, and all the coaches are knowledgeable, welcoming and offer modifications according to the fitness levels of the members.
There are several training rooms, which allow for RX Fitness group classes, Cross Fit and personal or solo training to happen simultaneously.
They have changing rooms and showers.

I highly recommend this gym to accomplish your fitness goals.

The first gym I was able to build muscle at! Very intelligent coaches and management that care about your health and progress. I have been doing the PulseStrength and RxPulse classes for the past year and have seen incredible results that I have always wanted to see and was unable to see in any other fitness program. These classes push you physically and mentally and are very rewarding once completed. I would recommend this place 10 out of 10 times over any other gym in the city!

Dennis and the RxFitness treated me like family. It didn't matter what level of CrossFit experience you had, they were eager to work with you and value to whatever goals were important to you.

From professional , respectful, high energy, it's plenty of benefits you get to enjoy when being a part of this family. If you haven't signed up yet, what are you waiting for???

Well, it's been a bit over 2 months since I started coming here and I am kicking myself that I didn't start sooner. Ugh!!! LOL!!

The classes, the people, the trainers... the atmosphere in general is exactly what I needed to move my fitness journey into the right direction.

I had been working out at home for a little while on a consistent basis but I seriously wasn't seeing results - and it was bumming me out.
But within a month of starting here, not only did I see a change in both my body fat and the inches going down, but I also saw a change in my frame of mind.

The coaches here don't let you give up on yourself but you don't want to let them down. You see how much the trainers care and want you to succeed in your fitness journey.

I have been pushed to limits that I never though possible and know that I am capable of so much more - with time.

There aren't only classes but this is a full Crossfit gym as well... and the Crossfit classes that I have seen (I haven't taken any, yet!) they are pretty intense and work every muscle you have and those that you didn't even know you had! LOL!!

So... if you are looking for a place that will push your limits and help you achieve those goals that you have been wanting, the staff here will not let you down!

Update... here we are a couple more months in and I still love it here. Pushing myself to the limit has been great!

I left my previous CrossFit gym after I became injured and the owner wouldn't reduce my membership cost despite not being able to take classes. That's when I stumbled upon CrossFit Severance. The owner, Dennis, worked with me temporarily on pricing until I was fully able to attend classes again. The coaches, staff and community are all exactly what I was looking for in a gym. Accommodating to all skill levels as well. Highly recommend trying out a class!

When I came here in 2018 I didn’t know what I walked into I need to admit I didn’t take it as serious as I should. However fast forward to 2020 I realized I needed to get back in shape and took full advantage of their RXPULSE classes. Dennis has created something extremely effective and addicting! Every instructor from Josh, Mark Fino to Katie have been amazing in coaching and elevating me. It’s a family feeling with staff and people you’re working out with. Bryan has been the main guy challenging me each class as I’ve shredded weight and gained so much knowledge, strength and conditioning to where I’m starting to build more confidence. I highly encourage everyone to take advantage of their complimentary class and see for yourself.

I would like to state first that I rarely write reviews, and mostly when something is not as described as received on Amazon. I was a member at Life Time Fitness for a number of years, but I decided to try RX Fitness because of a promotion. That was a turning point. Dennis is now my personal trainer and I could say that I'm only sorry I did not cancel membership at Life Time sooner and join this real GYM. I saw nothing but positive things here. Covid precautionary high hygiene standards, personal attention and nutrition advice. I would highly recommend.

Just received my 2 year anniversary email and I couldn't be happier with the decision I've made. They have been nothing but professional during the covid 19 pandemic. I feel safe and confident in their space. Cleaning is a bit tedious as every athlete must disinfect and clean their space after use but they are on top of it. Thanks for being a top notch gym!

I've been coming to this gym almost every day for two weeks now and already can say it deserves 5 stars. I myself am a bootcamp and personal training gym owner and also just had a baby so its been very difficult to find the time and energy to get good quality workouts on my own. I knew I needed a good gym and good people to push alongside with in workouts I didn't have to think of myself but I could trust to get my fitness up. So I dropped into RxFitness for a Crossfit session and after one class immediately signed up for the intro month.

For those looking for something other than Crossfit or even in addition to their Crossfit regimen, the gym also offers bootcamp/HIIT classes (Think Orange Theory / Shred), yoga sessions, mobility classes, and olympic lifting classes to provide what I see as a holistic 360 approach to fitness and also a way to vary you own training routine.

-Great daily training programming for people of all skill levels. Challenging yet doabale/scaleable/modifiable for everyone.
-Good class experience both in person and online utilizing apps to track your own performance and stay integrated with other members.
-The owner, Dennis, is very welcoming, helpful, and runs a good shop of other good trainers.
-The gym itself is well designed, clean, and has everything one would need.
-There is always an open gym option throughout the day if your schedule doesn't align with the classes.
-Everyone (the other members) are real good people and the environment is welcoming which can be traced back to a good coaching staff and management.

So far, so good! Looking forward to continuing to train here.

Knowledgeable coaches, clean and modern facility, well organized workouts for all levels, welcoming and positive environment. The coaches and staff were very professional and encouraging. Programed classes are diverse (yoga, cardio, crossfit, gymnastics, nutrition services, one on one training), in there by providing me the flexibility to work on my personal goals.

Very knowledgeable physical therapist on site, that provided lifelong exercises that I can take with me. Highly recommend!

Chicago Friends...

I have been to a lot of gyms and boxes and this is by far one of the best gyms I have been a part of. If you are looking for the best community and coaches, please swing into RxFitness- Crossfit Severance for a free class. This gym has helped make moving to Chicago easier and fitness fun. They have group classes, Crossfit, mobility classes and yoga so there is something for everyone.

Don't think. GO NOW.

I have visited the gym twice now, my first time in July, this started me on my CrossFit journey. I liked it so much I went back to Denver and joined a gym. Marco was so helpful and motivating my first visit I wanted to continue. This visit Ashleigh was great. But I found a bonus of James the body whisperer he does MAT muscle activation therapy. I have been nursing a sore hamstring and plantar fasciitis he helped tremendously. The equipment and facilities are five star.
Thanks for the workout.

I stopped in for a drop in class during a short weekend visit to Chicago. My cousin is a regular here and has been training with a owner Darren for years - and raving about him.

We joined a Saturday am group class - led by Ashley. Although I hadn’t worked out all week and was feeling sluggish- Ashley’s positive energy and right mix of motivation and challenge made the class very enjoyable and definitely kick started my weekend.

The gym is in impeccable condition- clean, all new equipment, spacious and generally a great space to workout in.

I will definitely be back for another class on my next trip to Chicago and highly recommend folks close by check this place out for an outstanding work out with even better trainers.

I have stayed active & worked out my whole life but never have seen the results like I do now training with Dennis. Numerous trainers in Chicago have done ok but he goes above & beyond for his clients. His gym is kept clean even in the process of getting everything finished ( can't wait to see when its done) His staff is friendly & everyone is alway's pushing you to do better. I recently just started getting meals from his FitChefs & they are AMAZING! I work in the industry with little time to prep so this is a major key for me staying fit. With only a few months in I have stayed a steady weight but lost inches & leaned out. He's truly been a Godsend, I couldn't be happier with the results i'm seeing and if your thinking of trying the gym out don't hesitate just do it. You'll be glad you did!
