Since I've started ClassPass Atlas Performance has been the hardest workout. TRX (Suspension Training) is no joke and the instructor Vance is tough. She split us into two groups, alternate between floor/ kettlebell workouts and TRX. Within 5 mins of TRX I had a good sweat going and my entire body engaged in the workout. 3 sets of workouts, 2 cycles through and like that 45 mins had flown by! I didn't know what I was getting into with this class but I'm glad I tried it and can't wait for the next challenge at Atlas. There was one thing I've never seen before. Another member of the class used my sweat towel during a 10 second break. This is more of a general Public Service Announcement: bring a towel, get a towel provided by the facility, or use your shirt. Please do not share your germs. The Best of Atlas Performance: -wide open facility -instructor was attentive, helping individuals with form throughout the workouts

Very awesome, very clean facility offering a wide array of Crossfit and strength/conditioning classes, with plenty of space left over for folks to do their own thing if they prefer. This gym has every piece of equipment one can think of. Most of the coaches are former college athletes of some type, and bring a wealth of education and experience to the programming. I just had my 1 year anniversary with Atlas and have nothing but good things to say about the people, values, and results that make this community what it is. Whatever your health/wellness goal is, there's an avenue to pursue it at Atlas in a top notch facility with smart trainers and good friends. I hope you check it out and it gives as much to you as it has to me.

Awesome box with top-notch trainers. Started crossfit here two years ago and have not looked back. They have a huge facility with three large rooms, so they can have multiple classes going at the same time. Besides crossfit, they also do CircuitFit, olympic weight training, MMA, and Fit360, run by a former NFL player, who's also one of the owners. This place has changed my life - went from not being able to run a block or lift a heavy weight (nor correctly), to having increased stamina and doing a 360lb. deadlift. If you're thinking about doing Crossfit, I'd definitely check them out.

I see Alyssa for personal training & cryo sculpting - absolutely worth every second & bead every of sweat! She has the most engaging and consistent moves to keep me involved and incorporates educational corrections to prevent injury - Nonetheless have see progressive and consistent results when I started sculpting & treating my inflammation with cryo-physio. Love that these trainers take the time to care and really hit each note where it matters. And of course the most clean, and organized space in all of River North.

I am 4 years into Crossfit and all of them have been at Atlas. This gym has something for everyone- They have a huge space for Crossfit and another huge space for their circuit training. Coaches are friendly and knowledgeable and can offer scaling for every workout if needed. Plenty of equipment for pros and beginners. Great place to go if you don't want to plan your workouts but want to get a great sweat and better results! Open gym hours on top of all the classes is a huge bonus! Highly recommend.

I have been CrossFitting for 6 years now and at Atlas for the past four. I've dropped into countless gyms and Atlas is one of the best there is. Huge facility with multiple rooms for different needs. Friendly staff, educated coaches, and welcoming atmosphere. Programming is challenging but doable, and coaches are always looking to help scale and give everyone the best workout for their skill level. I have made a ton of friends here, and enjoy every minute. I can't recommend Atlas enough!

Great overall gym for serious athletes. The coaches are thoughtful and keep the workouts very challenging and varied. Nice space, with a side devoted to crossfit and the other focused on Metcon/HIIT type of classes. Definitely more advanced and less fluff than other gyms... Workouts can be as intense as anyone would ever want and most people who go here are in really good shape!! Bonus: Free Parking.

I'm going into my second year of CrossFit and absolutely love Atlas. Outstanding instructors that are willing to take the time to help correct bad movement patterns and stay engaged through the entire class. They offer a wide range of challenging fitness classes for all levels! No matter your fitnes level, Atlas has something to challenge you! Clean facility and welcoming staff!

Amazing coaches and a wide variety of classes make this a great gym to be a member of. I always felt welcome and every instructor worked to remember my name, which is super important. Every class I took was challenging and instructors made sure that my technique and form was up to their standards. The environment is positive and welcoming.

I’ve loved training with Alyssa! She’s the best. She’s motivating, and her workout sessions have helped get me back into shape, and actually enjoy working out again. I’ve also done Cryo physio for recovery after workouts, and it’s been a game changer! Definitely recommend and will continue my healthy journey with her. Thanks Alyssa!

LOVE this gym! Excellent community, always a great workout, and very challenging! The coaches create their own programming so each class it's always different from the last. I think two solid pro's to belonging to this gym are 1)FREE PARKING and 2)Towels for showering! Huge plus!

Review for CryoPhysio with Alyssa: Alyssa uses her knowledges as a personal trainer to target muscles that need extra attention, which goes above and beyond normal cryo. The sessions are quick and effective, your body will thank you!

Started here right after Covid. Was very out of shape. Trainers were welcoming and helped me scale. Community is the best. The river north location just went through an entire renovation and looks great!

Recently had a Cryo Facial and a Physio treatment with Alyssa. She did an amazing job. Made me feel comfortable explaining the therapy step by step. I will definitely book wirh her again in the future.

I workout here but also do cryo physio with Alyssa. Been super helpful to help reduce swelling and start to work on recovery, plus she is extremely accommodating to my ever changing schedule :)

Visiting from out of town and love the instant community Chicago Strength provides. Wonderful staff, welcoming members and solid locker rooms to help me get cleaned up for my work day.

I have been at Atlas for almost 7 years. Hands down the gym offers more variety than any gym I have been to in Chicago and around the US. Great people, great facility, great coaching.

I've been a member for almost two years and would highly recommend! Getting an afternoon workout in with the CS community is my favorite part of the day!

I've been going regularly for a year for their lunchtime classes. Really knowledgeable coaches, and a friendly atmosphere.

Great gym offering both CrossFit and circuit training classes. Awesome facilities and coaching staff.

Attended a competition here (Galt Games). Welcoming and helpful staff. Huge, sprawling space.

Great facility, equipment, trainers and owners. Achieved all our fitness goals here!

You get what you pay for. By far the best Gym in Chicago.

Best gym in Chicago! Nobody offers the array of classes.

Great space, killer workouts, and an awesome community.

Great place to work out

Tom is a great owner!
