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 am so impressed by this place. Amber at the front desk and my coach I had today for my first class, Megan, they were both so nice, helpful, patient. They totally made the experience. I can’t tell you how many workout studios and gyms I’ve tried and nowhere has come close to what I experienced today. They make you feel supported the entire time so if you are nervous to give it a go, I encourage you to try. You won’t regret it. I had so much fun and the class totally kicked my butt and I signed up for the unlimited membership. I burned so many more calories than I usually do at the gym alone. I also love the heart rate monitor and seeing all your stats on the screen, it’s very rewarding and motivating.”

“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!”

“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!”

“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.”

“This place is dope! Let me tell you this, you will never find a better place to do boxing as a beginner. If you’re thinking about doing boxing or just getting in shape—go here. This place offers many variation of how your work out routine may look like. You can do weights, heavy bags and more. This place was built by a great coach, trainer and a great man. Thanks Sir, keep doing what you doing.”

“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 ??”

“They were very accommodating to my friend and I after being turned away from the other Naperville location. Thanks to the workers at this location for helping us out!”

“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 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!”

“Amazing community! Best energetic and motivating coaches! They take the time to show you proper form to ensure you are many progress. I’ve never been into lifting, but the community and coaches have motivated me to be here for over three years. Everyone is so friendly and fun.”

“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’ve recently switched to this location since it newly opened, and I love it! I’ve only been in a few times as I travel a lot, but it’s the best anytime I’ve been to. It is so spacious and has great equipment, and is always clean and taken care of.”

“This gym offers a truly unique experience. It’s perfect for parents—you can have your kids trained here while also focusing on your own workout at the same time. There’s no need to waste time just waiting around. It’s a great way to stay productive and involved, making fitness a family-friendly experience. Highly recommended!”

“Love the reformer pilates classes! Very friendly, supportive and exceptional mind-body awareness instructors. Definitely a must try studio, you won’t be disappointed!”

“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!!!”

“Harris helped with my daughter open an account a few years ago, since then, whenever we need anything, I text Harris. He's always there. Now we need to move and my daughter needs to go to college, Harris helped to cancel her account. As always, his service is efficient, patient and in a very good manner. Please see Harris when you need help!”

“There are a lot of negative reviews for no reason, I mean this is a amazing place I came here 5 months ago and built a lot of muscle progress, you guys come to a gym expecting it to be smelling nice and have all this fancy stuff but a gym is meant for hard work and if it’s smelling bad then your in the right spot with people who are working their ass off and getting stronger everyday, an amazing place to be and the community is amazing and pools and saunas are awesome and the equipment”
