Fitness & Gyms in Naperville, IL

“Super friendly coachs! They adapt the workout for you so it’s doable yet still challenging! Not to mention the other members at the gym are personable & friendly as well! Definitely recommend this gym!”

“I highly recommend Orange Theory and the central Naperville location. The staff there is so welcoming and go above and beyond to make it an inviting experience! One day I forgot to pack my shoes and a staff member had an extra pair I could borrow to help me get a workout in. That is going above and beyond for sure! The coaches are knowledgeable, dedicated and have a fun sense of humor. The staff at the front desk are friendly, patient and helpful. This is a wonderful place to workout and form a supportive community.”

“Seriously the best HIIT workouts I’ve ever done. I’ve loved every single instructor and the community is amazing here. Every class is uniquely different, the music/energy is top notch, and my strength is noticeably improved. Can’t recommend Shred enough!”

“As an elite member of OTF for over five years, I can confidently say this studio keeps me hooked! I’ve tried other workout studios, but none come close to what OTF offers. From the professionalism of the coaches to the cleanliness of the studio, the friendliness of the front desk staff, and—most importantly—the uniquely tailored workouts, everything here motivates you to push your limits and achieve your goals.

The classes are always challenging, sometimes competitive, and never boring. They frequently host special events like Dry Tri, Hell Week for Halloween, and marathons, which keep things exciting and fresh. The sense of community is incredible—it truly feels like a family. You’re always greeted with a smile and a warm tone, and it’s inspiring to see staff members working out alongside us.

The facility is extremely clean, including the bathrooms, and that attention to hygiene is greatly appreciated. Classes always start and end on time, and the coaches are both responsible and deeply caring. I’d like to give a special shoutout to Coach Ryan, Jess, Suzi, and Steve! Their dedication, motivation, and genuine care for each member’s performance make every workout worthwhile.

It wouldn't be an honest review if I didn't mention a less pleasant aspect- the space—it can get really crowded at times, and I feel that I don't have the freedom to perform the exercises at my best in these circumstances. I guess that’s a common downside for fitness studios in general.

Thank you to the entire OTF team for all your hard work and for keeping us loyal. You’ve created something truly special!”

“I've been going here for about 5 years now. Staff have always been helpful and great at keeping the place clean.

Shoutout to Devante for always being helpful with memberships.”

“My son loved the Homeschool Obstacles Class and Homeschool Beginner Class with Coach Rashawn. He's gotten stronger and more confident. The Coach is very good at encouraging but making them want it for themselves.”

“WOW!! I am a 62 year old female who had just gone through an L5/S1 fusion surgery. I was looking for a place that could help me begin my strength training. I absolutely love the small group weight lifting classes. The coaches help taylor each move to modify for any preexisting conditions.
But, most importantly, a happy, friendly, and welcoming place. I have found my home for my weight loss and muscle gaining.”

“Great place with an inspirational atmosphere. Joe works with all the clients and its almost like you have a personal trainer/coach. Great service and terrific value. I find the workouts leave you feeling invigorated. They are metally stimulating with just the right amount of challenge to keep you interested and moving toward your fitness goals. HIGHLY RECOMENDED”

“had a great experience at FORCE while traveling from out of state! Issac, Elliot + Riley were welcoming, friendly and checked in with me often while i attended classes. Coach Elliot even offered an invitation to lift with the Oly team, which was extremely generous (and fun). FORCE features a vast variety of equipment in great condition, challenging + intelligent programming, and a clean facility. members were very kind + offered camaraderie and healthy competition!

my only other feedback would be to catch email/web contact form communication sooner...i was trying to set up classes pre-travel so i could hit the ground running once i arrived in Naperville and it took awhile to connect digitally. i also probably wouldn't sub double unders for running for a gastroc strain. ? it all worked out in the end though. i would absolutely recommend this gym to fellow athletes. best of luck with the new rig installation and i hope to return at some point! thanks, team ??”

“You really need to update the massage chairs The Villa Park location has the best also please tell your staff to stop leaving the front desk unattended when people are trying to use their black card amenities it's ridiculous”

“I love working out here, it’s the start to my day. Katie and the trainers have made this place so welcoming. If you want a hard workout with fresh friendly faces this is your place!”

“One of the most welcoming gyms I have ever been to! The management has created such a positive atmosphere. It's a smaller gym, but never feels crammed and is clean.”

“I remember when I was in high school these guys use to come to our summer camp every year and I always learned a lot of from them. They made me a better athlete and thanks to them I know how to workout properly as an adult.”

“I'm new to Yoga and Pilates and I felt like it would be hard for me to do something new like HotYoga then I joined Hot Pilates and followed by Hot Bikram Express I felt absolutely amazing. It's hot like so hot but not so bad for beginner. Would recommend for everyone that wants to try something new and also release some stress & clear up your mind!”

“I’ve been coming here for a bit over a year, the coaches are very personable and fun! They will challenge you to the best of your ability and then a bit more. Over the years I’ve been trying to loose weight but only with UFC Gym was I able to loose close to 40 pounds!”

“I dropped in for a full week over the holidays and have nothing to say but great things about this place. Great programming, great staff (Sean is the man), and great facility! I will for sure be coming back. Thanks again for the fantastic experience,”

“Fry YMCA has been life changing for me and my family. As a single mother they have been beyond a support system for me. My children love all the staff and all they do for us.”

“My daughter is a member here and she recommended this location because it is clean and it has a feel of a private club. I met the owner, Mike, and he was very welcoming and charming from the start. I worked out noticing he cleaned the equipment meticulously and greeted every member with a smile. He took the time to make small talk with them and to me.

After my workout, he took the time to explain the different memberships and prices. I decided to join the gym. The gym is clean, the prices are reasonable, it’s not crowded, and you are greeted by a friendly person loving his job. Go Mike!”

“Although I’ve been a member of this gym for years, it wasn’t until this summer that I returned with real consistency, and I was genuinely impressed by what I found. The club feels refreshed, energized by a team that sets the tone from the moment you step through the door. You’re greeted warmly by the super friendly front desk staff. The gym is always clean, spacious, and well organized. The atmosphere is calm, respectful, and inviting. The leadership of General Manager Chris and Fitness Manager Mark clearly elevates the entire experience. Their presence is felt in the culture, the professionalism, the friendly atmosphere, and the overall quality of the gym. I feel that everyone at this gym is very supportive and invested in your success.

I’ve also enjoyed the group fitness classes I’ve taken so far, taught by Olga and Anayka. Which leads me to talk about my personal trainer, Anayka.

Working with Anayka has truly been life-changing. Before I started training with her, I was constantly getting injured, losing motivation, and never seeing real results. Since training with her, I’ve lost over 20 lbs, dropped about 8% body fat, and increased my muscle mass significantly. While the physical results are amazing, they’re only part of the transformation. The biggest change has been my mindset. Anayka has taught me how to train correctly, safely, and for the long run. Her knowledge of the body and the mechanics behind every movement gives me complete confidence that I won’t get hurt. She has the patience to coach someone as stubborn as me lol, and she makes every workout fun. I truly believe I can do this not as a short-term fix, but as a lifelong mental and physical transformation.

My family noticed during Thanksgiving. My cousins asked if I was taking “those shots” for weight loss, but no… it’s just the hard work, consistency, and Anayka’s expert coaching.

I trust her 100%. If you’re looking for a trainer who truly cares, knows her craft, and can change your life inside and out, she’s the one. It’s so fun to see the results every single week!!!”

“Between the location and amount of space available, LAF 59 has been pretty good to me. On the corner of Route 59 and 95th Street, it is in a very convenient spot. Compared to other LAF clubs in the area, it is one of the largest and perhaps that is what helps to make it a “signature” location. Despite how busy it would get sometimes, I could always find space to do my workout. In particular, I enjoyed the size of the aerobics room – it is massive and, as a dancer, I loved having all that private space to practice my turns, leaps and routines.

When comparing it to other health club brands, I believe that LAF is a great deal for the money. Last time I checked, a membership at Lifetime would cost about 5x as much as my current monthly fee here. For what I need from a health club, it works very well for me.

I will be re-locating and switching over to another LAF club, but I just wanted to give the staff here a shout out. My questions were always addressed and my concerns were always heard, and that is really all I can ask for. Everyone was always polite and professional, and that was much appreciated. Thank you!”

“Love this gym, nice, clean and well equipped. My only complaint is the non stop music, I as a Muslim don't listen to music, so I get my headphones and listen to Quran. Other than that, a fantastic gym.”
