“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.”

“Shred415 is an excellent option for anyone seeking a challenging, scalable workout. They have a clear vision for their routines, and it shows in the consistently high quality of their classes. Not to say that their classes are all identical - each presents a unique configuration of strength work and treadmill intervals. Rather, every workout can be relied upon to challenge you meaningfully. I’m very experienced in traditional strength training, but I was in a rut with standard gym workouts. Shred415 provided a great way to get out of my comfort zone and lean into my fitness *weaknesses*. Sure I can squat 3 plates, but I’m always humbled by these workouts! I would highly recommend anyone join who’s looking to break their workout status quo. My favorite instructors are Erin and Amy. Erin leads her class with spunk and energy without being cheesy and trite. Amy finds that elusive intersection of being both calm and motivating. Shred415 has been an outstanding experience, and I encourage anyone reading to give it a shot!”

“This place is genuinely so gas -hit one of my best PRs here. Really cool environment, and I feel like it creates a better lifting experience for everyone there. Doing something not many gyms do…”

“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!”

“Awesome gym, great trainers and equipment! I stop in whenever I’m in town and proudly wear their amazing shirts. If you’re in the area and need some fitness expertise these guys are great.”

“I have recently joined this incredible gym and have experienced the most welcoming and encouraging first week. It took me a few years (since COVID started) to get back into any gym consistently, and I so happy that I chose SPENGA in Bloomingdale. Special thanks to Carrie, Kari and Monica for kindly easing me back into elevating my health. YAY !!!”

“Great gym, amazing instructors, and welcoming atmosphere. Instructors care about your individual goals, assess your abilities, and strategically push you to make substantial gains. Blessed to have found Thunderbolt!”

“Very clean with good machines and free weights. Daniel was very friendly and helpful in getting me a day pass! If I lived in the area, this would certainly be my choice of gym!”

“Orange Theory St Charles is the best. Not only do you get a great workout but you also have a new community of people who share a passion for exercise and health. The staff is top notch - they are friendly, welcoming and know what they are doing. It is an amazing environment and I’m so glad I am a member”

“The high energy HITT team workouts are amazing! The synergy that Coach Tyler and Coach Lalo facilitate is intangible. Clean, professional, team oriented environment. Try for yourself, best of Glen Ellyn!Cheers to many more!”

“A really cool studio for group workouts. Trainers here are fun to work with. They always motivate you to take that one extra rep! Great equipment. It’s for all people beginner to pros, young to old, lean to built ..just everyone. I strongly recommend to check it out.”

“Had a blast at Tease Fitness for my sisters Bachelorette Day! The whole facility is immaculately clean, the staff was incredibly friendly, and all of us girls had such a great time. Our instructor Mallory helped us all feel comfortable and provided such a fun and professional experience! Would highly recommend to anyone who wants a full body challenge while having fun at the same time!”

“The staff is SO helpful and kind! Alexis is so patient and takes her time to explain everything and take you through how to reserve your spot and log your workout! It’s ALWAYS clean and welcoming!”

“I love the place and atmosphere at resurgence, i have never went to gym before this, i have tried Pilates but im into yoga since 8 years. My trainers at gym Julia and Denisse are wonderful people, they understand me and the best is never push me out of my limit but in such short time they have understood my body and they motivate me and encourage me to take one step at a time. I didn’t know that i will be able to lift weights but i’m and thats a new thing i have learned about myself. My love my batch all the ladies are wonderful and they all try to guide me as im new to the place and workout. The best part is everytime i go to class, im doing something new, and the machines that im using are amazing the target my trainers give me i like that as it motivates me to set things the same way in life. Thank you Craig and team you are doing great job.”

“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”

“I am a new member and had my first class today - Amazing! I have had physical trainers in the past and I have never met anyone more devoted and compassionate than Rondi and her team. She knows her stuff!!! She truly loves what she does and isn't just some "health coach" or "trainer" you see pushing for likes on tiktok. I have been in rehabilitation from a very traumatic car accident for almost 2 years and had to have reconstructive surgery on my spine. She literally puts in more effort than my physical therapists! This place is a hidden gem and I am so blessed I found her! Can't wait to rock this new membership and my new health journey. Thank you Rondi!”

“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.”

“I am physically kind of lazy, which never bothered me until I hit 50 -- at which point I started to feel decades older and found myself spending much of my free time on the sofa (I have a job that requires sitting at a computer all day). After a stop-and-start sort of year, but for the last 6 months working out pretty regularly 3X a week for 30 min at FIT, I feel as though I've recaptured a huge part of my youth. No more am I dreading crouching down to look at something on a lower shelf while out shopping. No more am I avoiding doing simple things like cleaning out the garage or handling simple yardwork. I have more energy and more flexibility and feel competent to do physical things. I didn't realize until recently how much PAIN I was actually in because I was so inflexible and had so little muscle tone. Wish I hadn't listened to all those people who said it wasn't "worth" going to the gym unless you committed gobs of time. I really am indolent and made a truly minimal effort, basically just showing up, but it's made an incredible difference in my life and my mood just to be able to move easily. My only regret was not starting years ago rather than at age 54 (now 55). Jan is a wonderful instructor and offers training that is practically one-on-one in a relaxed atmosphere, but does "push" me enough that I feel that I've accomplished something. I really can't imagine NOT making time to work out in the future. Love the gym and love the people. The one-on-one sessions are great, too. Can't say enough about what a revelation it has been to feel good. It's improved my mental health too.”

“The best powerlifting gym in the area. All the best equipment for powerlifting, strongman, olympic lifting. The owner is awesome and has built a community that's inviting for lifters at any level. Not only that, the people at the gym are friendly and helpful. Can't recommend it enough to anyone in the area or for visitors.”

“Extremely positive and welcoming environment with coaches that genuinely care. Whether you're doing the workout or the day or your own thing, someone is always there to support you and give you advice. Super grateful for kick-starting my fitness. And oh yeah you'll get great results”

“The gym is amazing and well diversified. The equipment is stellar and world class; in fact, some of the pieces are the latest in gym technology. In addition, the gym is extremely clean.”

“This was my first ever experience with CrossFit and honestly, it couldn’t have been a better intro. Everything at this gym is just dialed in—super well-organized, form-focused, and run by people who genuinely care about your growth and safety. The community here is also something special—friendly, motivating, and full of good energy. You never feel out of place, no matter your level.

Huge shoutout to the coaches Arianne, Jake, and Erach—absolute legends. Their attention to detail, constant support, and ability to push you in the right ways made every class something I actually looked forward to. They create an environment where you’re challenged, but never overwhelmed, and always encouraged to get better.

If you’ve even thought about trying CrossFit—or just want to be part of something that pushes you, supports you, and leaves you walking out stronger every time—stop scrolling and pull up to this gym. You’ll know exactly why from day one.”

“OTF Glen Ellyn my life changer, I spotted this place right in time after four long years of break from sports and my fitness journey. From being a self trained athlete to becoming an over weight 27yr old. I felt under confident with my weight gain and unhealthy. When I first entered the studio. I had a very warm welcome from coach Katie and Zach from the front desk. I was never a gym person before but the atmosphere pushed me to give it a try. Ever since I started I never looked back, always came back home feeling stronger physically and mentally, my workout pace and endurance has highly improved with every session. I so far trained with almost all the coaches ( Katie, Ellen, Angela, Abby, Matt) had a great experience with each one of them, everyone were highly knowledgeable, super supportive, has their own unique style of training. Its hard to pick favorite's but Coach Katie, Ellen and Abby have constantly ensured if am doing okay and guided me from the very beginning. Little did I know that my journey would only last for two months due to career transition. Today after completing my day four of hell week session which is my last session here I felt a sense of void that’s because I’ll miss OTF glen ellyn a lot. But I’ve made my mind to be with team orange wherever I go and continue to grow. To all the folks in Glen Ellyn area who are looking forward to start your fitness journey I would highly recommend to try this place out and feel the difference in you its worth every penny you invest in if you’re hard wired to stick in this transformation journey !!!!!”

“I came here for a few drop-ins during my visit to the Wheaton area. Jason, one of the owners, was great and super hospitable. There was a really great atmosphere in the classes, and I'll definitely be returning when I'm in the area again.”

“My friend and I just made our membership with manager, Josh. The process was smooth and easy. Josh was very accommodating, I highly recommend to anyone in the area.”

“Visiting this gym and how great the staff is. Working with Becca here. She has helped me learn how to eat better. Also the gym is very welcoming to come an work out. I have to say that if you have questions staff is there to help you out in anyway they can.”

“Excellent gym! I was in town for work and dropped in. Great facility, people and coaching. It’s always great when you drop in and are made to feel welcome and get some good coaching. Easy drop in process and great workout. If I’m back this way will for sure drop in again.”

“Such a great atmosphere and they have a large number of coaches that all bring different strengths and unique qualities. They all do a great job of explaining the workouts, but then also giving guidance on proper scaling for every level of fitness. And they do a phenomenal job with their kid’s and tweens/teens classes! They are patient and inclusive with every kid in class. They know when to push and know when to pull back based on the child’s personalized needs. It’s evident they truly care. Whether it’s for an adult or for a kid looking to stay active and build their confidence…I’ve never been to a better place and I’m grateful for the programs they offer.”
