One of the most open and welcoming gyms in the area. Workouts are targeted to different areas of the body and rotates throughout the week. Worth the money!

Great atmosphereArt really knows his stuff. Able to make a beginner feel comfortable.

A very clean and impressive indoor athletic rec center. I attended a soccer game here and I was impressed. I wish we had something like this closer to home.

This is the coolest fitness studio I have ever been to!!! Art, Liz and Cody are top notch their style of training truly gives you results! They have the best when I say best I mean best accountability system in the world. And let me tell you the nutrition plan is AMAZING!!! I lost 32lbs and 8%BF in just 6 weeks this program has changed my life it’s like a family they actually care about you and what your goals are. Thanks again Opposing Force you guys rock

I love the atmosphere and every single one of the trainers (Art, Cody & Jake). Liz is great with the food/meal plan questions! She has very creative suggestions! They truly feel like family! I am just wrapping up my six week trial and Im so happy with the results!!! I am down pounds and body fat!! At my age (51)... all of that happens at a slower pace. But if you follow the meal plan and show up for the workouts…you will see the results! Im ABSOLUTELY going to continue to work out there! Super positive environment! 👍🏼

AWESOME! I was going to another gym and didnt see results. This place is supportive, positive and encouraging in all aspects. From day one they corrected my form with the workouts and theres a noticeable difference just after a few weeks that I am now engaging the right muscles and feeling results. If you are thinking about it, just sign up, you wont be sorry!Update: This gym is AMAZING! If you want results sign up! Fabulous trainers, nutritionist and the support of the best group of women around. The combination of training, accountability and support really helps you be successful. I have personally lost 50# in 6 months and so excited to keep going!!

I wanted to love this place. Cody is awesome. The workouts are good. The problems for me were nutrition and marketing. I did the six week program. The nutrition program did not work for me. I lost weight just fine, but it wasnt healthy for me. I ended up going to both a doctor and nutritionist. The no fat diet messed my hormones up. The six week program is free in so much as the money you give them up front is then used to stay at the gym. The gym is expensive! 45 a week is their discount program, but they have memberships as high as 89 a week. There are a ton of gyms that have small group training for much less.

What can I possibly say about Opposing Force? Amazing people are naturally attracted to this place, from the awesome trainers, to the women who understand that everyone is putting in effort. We are a family, a group that understand support, joke and care. It isnt just positive motivations but the dark sense of humor, sharing in each others day and relenting in the misery at the moment but the amazing results you get at the end. I personally joined for a 6-week challenge and have been hooked. Cody gets it, he somehow manages to look at the room and cater to each individual needs and makes me happy I showed up. Art is where is all started and brings his passion for womens health out there, with lots of jokes... Liz is what rounds them out, helps motivate you with nutrition, understanding and being a badass in the gym, seriously watch this women squat.Then there is Jake, hes new and already gets it, he smiles and you know something fun is coming.Opposing force will bring you the people to support you in all aspects of your life, and will HELP you achieve the goals you set. What you put in you will get back. It is up to you to show up and do it! This really is a family.

Art, Liz and Cody actually CARE about you hitting your goals and becoming the better you. Want to lose fat? Drop weight? Or maybe just look and feel your best? This is it - period. Do their 6 week challenge - it gives you amazing workouts with a trainer, a personal nutrition plan and a team of coaches to make sure you do it to get amazing results like me💪

Love this place. It has everything i need. It is 100% a 5 star gym for me. However, others may not feel this way as there arent locker rooms, towels, or showers.

Absolutely LOVE this gym! The coaches are so encouraging and supportive. Not only are the workouts challenging (in a good way), but they are always different. And the nutrition coaching was exactly what I needed. I feel transformed after only 5 weeks! Cannot wait to continue on this journey.

I’m about to complete the 6 week challenge. It’s a great program to help you get back in shape. The amazing team (Liz, Art and Cody) are truly dedicated and always go above and beyond to help with in person fitness needs.It’s such a welcoming place and everyone here is so supportive. Highly recommended!!

I started out with the 6 week challenge and instantly saw results. If you do the work and follow the meal plan you will see results. Not only did I accomplish getting my figure back but I also gained my confidence and energy back. This place is more than a gym, its a family. Art, Liz and Cody are amazing and you can tell they truly care about what they do and every person that walks through their door. The support system is incredible and I highly recommend any woman who struggles, check this place out, it is so worth it!

This gym is awesome!!!They push you just enough to know you doing it right, each and every workout is different and challenging.The motivation you get and feel after one of the workouts is exactly what you need.If you need a fun, energetic, killer ab, booty work out check them out 💪

Havent worked out consistently for about 4 years due to some digestive health issues but this 6 week challenge was just what I needed to get back into it. Feeling stronger and getting my energy back. Small class sizes with a different workout each time keeps things from getting boring and you use different muscles each time. The instructors are wonderful and encouraging too!

I was so hesitant when I first signed up, because I had not worked out in a while, but all my worries were put at ease quickly. The trainers at the gym help modify the workouts if you need it and walk you through any exercise that you dont understand. Art, Liz, and Cody are all have great energy and make the workouts tough, but they make sure to support and push you while keep the atmosphere fun. All the other ladies that go are just as supportive and positive.

Best gym ever! I cant say enough good things about Opposing Force! If you have 100 pounds to lose or if you are extremely fit and want to maintain your current fitness level (or anywhere in between) you will feel comfortable, challenged, and supported at Opposing Force. The workouts are tough but fun. But most importantly, what sets this gym apart from all others is the focus on nutrition and accountability. Im in my 40s and am in the best shape of my entire life. Ive dropped over 10 percentage points in body fat, gained muscle and definition, and feel great! Thank you Liz, Art & Cody!

I wanted to wait until I was pretty much done with my 5 so challenge before I fully reviewed this place. I have to say 5 stars without question. Starting a fitness journey, lifestyle change, is so DIFFICULT and the support is not always there. Liz and Art have created an environment of WONDERFUL trainers and awesome women who are all in different stretches of their journey and put them together is such a way that made me LOVE it here. When I found myself feeling like BLAH-which can definitely happen on this journey- they were right there to let me know I can do this! When I felt like I couldnt figure out food I was able to send them a quick pic or message and they were able to assist me asap. Ive been supported by the women here and everything-you can do it, good job, keep going! This is a GREAT place to kick your ass right into the healthy fit journey that you want!

A few weeks into the 6 weeks program and its been amazing! The coaches (Art, Cody and Jake) are always watching to make sure our form is correct so we get the most out of every movement and dont get hurt. They are also cheering me on as well as the other ladies in the class. It is a great atmosphere!!! Liz is a master with nutrition; helping reset my metabolism and kick start my weight loss and fitness. The support does not end at the gym doors, they are available at the push of a button whenever I have a nutrition or fitness question, which is great!!!

This club is the perfect place for a great workout and great conversation. No matter when I go I can count on Liz, Cody, or Art to push me for the perfect workout. Using their personal touch they turn a workout into a self-reflective building experience!

Love Love Love this place. Challenging training that’s constantly changing, amazing trainers, fun and supportive atmosphere, and incredible results!! They always push me to perform better every day and never letting me settle for anything less than my best. Its a place Ive been able to commit to and consistently go to because it makes me feel amazing and has given me great results. Would absolutely recommend to any woman serious about improving their health!

Love this place. Art, Liz and Dave are fabulous, the ladies I workout with are bad ass, super supportive and motivational. I feel sore and amazing after every work out. Best part is no one is just a number or just a client. Definately, more of a family/good friends atmosphere. These folks are passionate and take personal approach about helping you be the best you can be.

Walking into Opposing Force Training was a day that changed my life! I wasnt looking for a way to comply lose weight, for another yo-yo diet, or a way to break the bank paying for personal training at a big box gym. I was looking to find myself again, to make a lifestyle change, and to really find someone to push me and to get myself healthier from the inside out. Opposing Force Training has helped me find all of that! Art and Dave really care about each and every member of the gym and go above and beyond to help achieve the goals everyone has. No matter the level of ability or fitness everyone bands together with support and motivation here and it is more than a gym it is a family and one I am thankful and proud to be a part of.

Amazing Gym! Opposing Force is the 1st gym that I have loved. Awesome trainers that show you the right way to workout. Results are unbelievable - I have muscles now and down 27 lbs! :)

I have been going to opposing force for almost two years and I couldnt imagine my life without it. It was difficult when I first started but as I saw the weight and inches drop off, I stayed motivated. I hit my goal weight over a year ago and since have learned how to maintain my weight and still enjoy the foods I love. This gym not only helps you reach your goals but teaches a healthy lifestyle. I have made so many amazing friends along the way as well. It really is nice going into the gym and getting to see people Ive grown close with everyday.

Strength Republic discriminated again me because of a little dog hair on my clothes from my SERVICE DOG! They actually kicked me out because of it. This is highly illegal and they are very lucky I didnt pursue the issue further. They also basically require you to wear tons of perfume unless you dont sweat at all while working out. I am highly allergic and they kept trying to tell everyone they had to spray themselves with perfume when they got there. It was crazy. I would never recommend this place. I am using an assumed name because Ive heard many stories of Art (the owner) taking vengeance. There are many other places that offer a much better service that wont discriminate or expect everyone to smell like flowers while sweating from working out. Its a gym afterall.

This was the best decision I made for myself. This is a place where they teach you, motivate you, and strive to make you be the person you want to be. I couldn’t be happier and they are now people you can call family. If you want someone to push you in the right direction and hold you accountable this is the place! You will not be disappointed!

I love this gym. Intense workouts and friendly trainers and ladies. Ive had many back surgeries & if I can not do an excerise the trainers are amazing with giving me an alternate exercise that wont hurt my back. The atmosphere is always happy, friendly and fun. I would recommend this gym to everyone.

Great place to workout. Everyone is very encouraging. I have back issues and the trainers are more than willing to give me modifications so that I don’t hurt my back again.

The day came that even elastic waistbands were no longer my friend. I completely grew out of my clothes but I was in denial. I was having a moment. As I scrolled FB I saw a post about the 6 Week Challenge at Opposing Force.“Click to learn more!”“Click to schedule a consultation!”During my consultation with Art he asked me why I was there. My response “because my underwear hurts!”I jumped right in! I didn’t give myself time to make excuses. Best 5 second decision I’ve ever made.Joining Opposing Force changes more than just your waistline. It changes how you feel about yourself. The staff has truly created a culture of connection. They submerge you into their tribe and you instantly feel like you belong there.I could barely do a sit up and now I am amazed by the progress I have made.Thank you Art, Liz, Cody & Jake you are fabulous!

I had struggled for years to lose around 10 pounds...and lately, I had just lost the motivation to push myself. Well...Opposing Force came into my life at the perfect time! I signed up for the 6 week program and learned that I COULD be committed to myself and my health! During the 6 weeks, I lost over 5% body fat and 13 pounds! What I had been trying to do for years was accomplished so quickly!Liz, Art, Cody, and Jake are amazing. They honestly care about you- they get to know you and make themselves available to whatever you need. Cody was my trainer and he pushed me to succeed and held me accountable every time I stepped into that gym and even after.Opposing Force is an amazing place that cares about the well-being of women. I seriously recommend it to ANYONE!!!!

I love this gym!!!! Trainers are encouraging and supportive and also see if you slacking. They see when you need to slow down and when you need to push harder. They very knowledgeable, and they really having fun doing what they love.

I couldnt have been any luckier by finding this place. Everyone here is so supportive, trainers and members! Every day I feel stronger, physically and mentally. Best place to go to work out and see progress whether youre a gym veteran or starting off new!

This is probably the nicest gym. They purposely keep the number of members at a low maximum to ensure equipment is always available. They have the latest gym equipment.

Seriously love this place. Art, Liz, Cody and Matt are awesome, they keep you accountable and motivated. I highly recommend it! Ive only been here 3 and half weeks and have lost 3% Body Fat already.

This is unlike any experience I have ever had at another gym. I have been hooked on Opposing Force for 16 months now. The trainers are fantastic! The workouts they come up with each day are always new and exciting, and they also help each client come up with a nutrition plan to help them meet their personal goal. Art, Dave, and Liz genuinely care, and they take the time to get to know each client on a personal level. I have also met so many strong, amazing women at Opposing Force.

Trainers and coach that cares about people and their well being not just about money. They are truly the best. If you need to get fit in a serious/fun environment this is the place for you!

Trainers and coach that cares about people and their well being not just about money. They are truly the best. If you need to get fit in a serious/fun environment this is the place for you!

Love this place! Wonderful support community for women who want to work out, get strong, get fit. Includes nutrition accountability too!! All inclusive support!

I just started. I totally love this place. Everything from the people that go there (super nice) to the trainers (i think they undercharge for what they provide) to the look of the gym (not like an dirty crossfit box).

Great place for a person like me to go. Diagnosed anxiety I am realizing has kept me from working out for fear of judgement. This place judges NOBODY. Everyone is welcome no matter what. The staff is encouraging and makes me feel completely at ease.

OF THE HOOK! Something special about this place will get you addicted! Maybe its the awesome trainers (that really do care about your progress), or the kick ass workouts or the comfort level & good music. Either way you wont want to stop once you start. I wanted a place that had a good, serious mix of weight training & cardio, minimum fluff, and OP4 is it!

Wonderful fun and funny staff that will challenge you, and show you the right way to work your body in all aspects. Nutrition to workouts they have it all and make it fun at the same time.

Ive never though a place could become as necessary as this one is now to my life! Amazing team! You ass and feel results as along A you commit!

I just finished the 6 week challenge and Im so glad I signed up! I have tried other programs in the past, including Weight Watchers, hiring a personal trainer, and the Beachbody 21 day fix, all with limited results. Ive had an especially hard time losing the many pounds I packed on due to taking mood stabilizers. Frustrated and desperately seeking a program that would help me shed pounds for my upcoming wedding, seeing Lizs video was a call to my soul! I decided to fully commit to the program and hope for the best... In 6 weeks, I lost just over 11 lbs!I love the Opposing Force familia. They are a quirky group but they keep things entertaining! The workouts with Jake and Cody continue to kick my butt every morning. Your sore muscles will be a testament that its working! Its great that you get individualized coaching on your form even in a class setting. The nutrition plan provided by Liz really does get results! I also love that the trainers are constantly checking in with you, ready to answer questions and keep you on your game. This family is a fun one: they have themed workouts for holidays and put together extra contests to help everyone achieve their goals. Ill be sticking with this gym for the long run because of the results!

I love this gym! The boot camp has been the jump start I needed! Only a few weeks in and seeing great results! The staff is motivating and supportive! I highly recommend this gym!

I saw an ad for a six week challenge on Facebook for opposing force. From the moment I stepped into the gym I really felt like I was in the right place! The support and accountability is exactly what I needed to get back on track with my health. At 46 I’ve learned again that I can do anything, no excuses! Putting yourself first, having the support on nutrition, workouts and positive self thoughts is a priceless gift! Meeting Liz, Art, Jake and my trainer and now massage therapist Cody has been absolutely life-changing! I’ve had a lot of sports injuries from the past, everything is customized to you as an individual.You will not be sorry to take the first step, trust me they will all have your back!The workouts are fun and always changing, the music is great and before you know it your work out it’s over!I’m all in, warning ⚠️ you will get addicted!I ❤️ my gym!I ❤️ my opposing force family!

Unlike any gym I have ever been to. This is the most satisfying and result driven I have ever felt and been a part of. They help you like no one else has ever done. They are by far the best.

Seriously the best place around! Its a tough work out and I always feel great after!! Never boring and a fun atmosphere.

Absolutely love this place! I am full of energy. I am more confident in my body now, and its been only 5 weeks since I started the training program:). Feel great every single day.

Art Roman is a truly excellent trainer. He is the perfect combination of tough (Art, you are KILLING me!) and warm (Milly, you are doing so good), and because of his efforts, I am stronger and more flexible, I recommend OP4 without reservation.

This gym is just amazing! I feel more motivated now then I ever have before! Great staff and great environment!

So glad I joined Opposing Force! The staff is awesome- they are all so knowledgeable and supportive, but push you to do and be your best. If you are looking to make big changes, this is the place!

This gym and team is much more than I would have ever expected. The coaches work you hard, but motivate you even harder. It is not your typical gym, but that is exactly what I needed. After a successful, long, hard, earned 6 week challenge I would say it was completely worth all the pain, sweat, and tears I shed. I highly reccommend this gym if you are looking for a serious kick in the butt to get in shape and on the right track.

I am 48..doing the 6 week challenge. .feeling stronger than I have in years.Art Liz Cody and Matt are wonderful and supportive.I was really ill.last year and my health suffered.I am so happy that I said YES...Great place.

Started going a little over a month ago and have loved it ever since. Everyone is there with the same goals in mind and the staff is wonderful. Would recommend to anyone.

I am two weeks and I am hooked. The staff is supportive and encouraging. The program they set up for me is attainable and challenging.

Best workout! Opposing Force has great trainers and an effective, unique workout format! I love it! 😃

I look forward to my workouts and get irritable when I DONT workout. Who can say that about their gym? From the gym, the trainers, and the other members I feel like I belong to a family and have been consistent here for over a year.

Opposing Force has helped me to overcome weight goals I never thought I could accomplish. If you live in or around the area, and you are serious about challenging yourself, changing your lifestyle, Opposing Force is the place to be. Art Roman, Dave ODowd and Liz Shaffer will definitely bring out the best in YOU!

One thing that sets this place apart from the others is that although they give you the tools YOU are held accountable for YOU. When you’re amongst a group of women who struggle with the same things as yourself and your coaches want to ACTUALLY see you win and get results to me that is beyond teamwitk it’s a FAMILY. Super happy I made this decision.

I love my gym! Trainers are awesome and always pushing you past your comfort zone.

A few years back I was looking for a gym to help me grow into a healthier lifestyle, at that time I found a Groupon for Opposing Force and decided to try it out. From day one I felt at home, there was no pressure, no stuffy gym setting, a trainer whom was personable and women of all shapes, sizes, ages and races encouraging one another to make eachother better. That first day at the gym was four years ago..... Ive gained many friends/family, and am very thankful

I’ve been coming to Strength Republic for a week now and I absolutely LOVE it!! I leave every class with my arms shaking with fatigue and it’s the best feeling in the world (as crazy as that sounds 😜) I felt my abs for the first time in a long time after a workout on Saturday and I got super excited for my future results!

I love the atmosphere at Opposing Force and they are great and motivating people. Thank you guys for pushing me to be the best me.

So excited to be a part of the Opposing Force family! It has been a game changer! Stronger..happier and healthier!!

Ive been amazed at the results Ive achieved. Not to mention the incredible woman Ive met. Art is awesome, takes the time with each person to help with posture or pushing you to your next goal. Wish I would have started this sooner but now Ive been sucked in and I pretty much live here. Dave is a newer trainer to OP4 and very dedicated and helpful as well. Liz teaches PiYo which is a fun challenging class fusion between Pilates & Yoga. All and all love this place and my results!

More than just a gym, it is a family that pushes you to be the best version of yourself. Dedication, motivation, drive, comfort, lifestyle and energizing are just a few of the words that come to mind since I’ve joined!

These guys rock! I lost over 10 lbs my first month working with them. Their training is fun and effective. Cant say enough good stuff about Opposing Force.

Pound for pound the best gym and program out there right now, the 6 week challenge is amazing and I cant thank these guys enough :)

Love love love this place! Losing weight has never felt so good! Im continually pushed to my limits by the awesome coaching staff, and Ive been able to change a lifetime of bad habits into productive growth!

Great place to work out the trainers Art, Cody, Liz and Jake make sure you stay on task and assist if needed.

I took a free class on Labor Day and was hooked immediately. The atmosphere, the knowledgeable staff, the fun trainers and the class structure are all exceptional.

One day I was checking my Instagram & came across a 6 week body makeover challenge on Instagram & thought I could really use that. I’d signed up for gym memberships in the past, ordered all the workout dvd’s, would do a few times and go back to my same routine. What I needed was a structured program with flexible workout times, for someone to tell me the right foods to eat for my body type & help me measure & track my progress. Trying to do it all on my own was challenging because I’d become easily frustrated with wanting to see instant results but just didn’t know how to get there. Taking the 6 week challenge was life changing for me. I met other women going through the same frustrations I’d been going through & we instantly bonded. It’s not like other gyms because they offer advice and support outside of the gym and will answer any questions regarding any of your dietary concerns & needs. I needed that! I not only lost weight & body fat but I am no longer tempted to eat fatty greasy food or crave chocolate or sugar. I finally feel more energetic & am even strengthening my bad back which I’d thrown out twice in the last 2 years. I love it so much I signed up to keep going even after the 6 week makeover and am able to fit in my clothes from 2009! I’ve even inspired some friends to take the challenge so now we are doing it together! If you’ve tried it all and you haven’t been able to get your body in the shape you want to be then you need to do yourself a favor and take the 6 week challenge at Opposing Force Gym. I wish I knew of this years ago but I finally did it and you can too! Quit being so hard on yourself, it’s not easy doing it on your own. All the tools you need are here to help you get the body you want. You just need to do it!

I participated in the 6 week challenge at Opposing Force in Lisle in an effort to jump start my weight loss after having a child and surgery. I knew Id get some intense workouts and meet some people along the way. I had no idea how vested the owners and trainers would be. Art answered all my questions and made sure my movements were precise to avoid injury. Hes personable and approachable and goal-oriented. Liz helped with nutrition. I was still breastfeeding and she helped me customize my diet to make sure to lose weight while still making enough milk to feed my little one. Cody makes a connection with everyone and shows an interest in the entire person not just the gym version of the person. Its not at all intimidating having a male lead a female workout class. Sometimes Liz joins the class which shows how much she believes in the program. Its a bit expensive, but you get nutrition support and workouts planned for optimal weight loss. Liz also posts weekend workouts on Facebook that require little to no equipment. Liz and Arts dedication to healthy lives is clear. They genuinely care about all of their clients. Cody does too. They are the reason I pushed so hard during classes. You may have previous injuries or limitations and thats ok. Codys got your back. He modifies when necessary and supports you the whole time. You will not be disappointed with your results if you listen to them and follow the program. Give them 6 weeks (and maybe quite a few more if you like what youve accomplished).

Absolutely love this place and Art and Liz! Make you feel like family and feel comfortable doing what you do !

I’m new in the area and joined the gym because I was looking for a custom program to get in shape. By far, it’s surpassed all my expectations and I’ve been a part of a few CrossFit’s and did Orange Theory. What a difference it is having a custom program for my goals than just working out somewhere off and on.I stated with the 6 week challenge, got amazing results, over 6% body fat lost :) I fit into clothes that been sitting in the back of my closet for years and my husband loves it!!!!Liz is amazing at customizing nutrition and coaching is better than anywhere else I’ve been. Cody, Jake, and Art are all fantastic at what they do and how they coach.I saw someone’s review below complaining about money.. So.. I wasted a ton of $ in the past at lifetime, bootcamps and Beachbody stuff that didn’t work for me. This is probably the most expensive gym I’ve been to and honestly I would pay double to be a part of this amazing place and be a part of the group of women that train there. Quality trumps quantity.

Great, great place to get your body back in shape. They get 10 stars from me!!!❤❤❤ this place.

I am one year in and there is no turning back. I have become part of a family that cares for each other and helps each other out. I look VERY forward to my work outs and get very upset when real life gets in the way and I miss my work out.

Absolutely love this place. The trainers, the workouts, and the camaraderie are all amazing!

Opposing Force is awesome. So far love it.

Couldnt be happier with the training, support and encouragement from the team as well as the other members. Just a month in, feeling and seeing the results. Im hooked!

Fun group
