I absolutely love Undisputed! It’s my go-to spot for unwinding, dreaming, and letting off some steam plus getting stronger and healthier. I've been a part of the Undisputed community for quite a while now. I started in my thirties and now I’m in my 40’s and feeling the best. I've met some of my closest friends here, along with the love of my life. It truly holds a special place in my heart!

I would tell anyone to walk in. That’s the hardest part but I promise you wont regret it. Thank you Undisputed.

Joining Undisputed has been one of the best decisions I could have made for my health and wellness. In the past I was never comfortable doing strength training or honestly even group fitness activities - now I can’t imagine not having this program as part of my fitness lifestyle. The Undisputed coaches and members were incredibly welcoming, knowledgeable, and supportive. I am healthier both physically and mentally than I have ever been before thanks to Undisputed.

Joining Undisputed has been one of the best decisions I have made for myself both physically and mentally. I have been enjoying my membership for a year and a half and have no plans to quit. I started 18months after having my 4th child, nervous but ready for a change in my health. I have been able to lose 25lbs and also gain muscle mass. I enjoy the workouts and the coaches and fellow members have become friends. I love the motivation from BK(owner), the many Challenges throughout the year and not to mention my love for the Juice, their hydration supplement. If you’re on the fence and need a little push, let this be it!

I’ve been training at this gym since July 2023, and the experience has been life-changing. I’ve lost 30 pounds by following the coaching and learned proper posture and powerlifting form while building real endurance. The workouts are programmed in a way that actually improves recovery the more consistently you train, which has helped me progress faster than I expected.

What stands out most is the quality of the coaching—every workout can be adjusted to meet your current ability, so no one feels left behind. The coaches truly pay attention and push you to reach your potential safely and effectively.

What I didn’t expect was the sense of community here. Everyone encourages each other, celebrates milestones, and makes you feel like you belong. It’s not just a gym; it’s a supportive environment that keeps you motivated to keep showing up and growing stronger—physically and mentally.

If you like to work out alone, doing the same routines day after day and week after week, join the place that’s open 24/7 for $10mo. If you are looking to get healthier in a space where you have constant support from coaches, not just on exercise but also diet and short term or regular physical limitations, this is the place for you. The coaches are there, not just to lead the classes, but to answer your questions, make sure your form is correct, modify the workout for you if needed, and encourage you. This gym, the coaches, and the owner (BK), foster a community of support, fun, and fitness. The workouts are amazing and the people are even better. They regularly do 3wk trials for new members, who receive their own coach during this time. If you’re looking for a new gym with a fun and supportive environment, check out Undisputed and enjoy improving your health and strength.

I do not even know where to start to be able to convey how amazing this place is! I started over a year ago just to give it a try to see if I would even like a fitness program like this. I went from ever only doing a treadmill and feeling insanely lost at a regular old gym- to being here 6 days a week and feeling so sad if I miss a day. The owners are absolutely amazing and put their all into every program, every workout, and every person that goes there! I never in a million years thought I would enjoy going to the gym but the community here is unmatched to anything I’ve ever experienced. If you are looking for a gym to feel guided, supported, loved, pumped up, and like a party of a family- Undisputed is the place to go!

Thank you BK, Shae, and everyone else that makes us all feel like family- my Husband and I will forever be a part of the Undisputed community ❤️💪

And ps- I absolutely love the loud music 🤘

You will not find a better place to better yourself and family. No words can express how much this facility means to my family. If you have been longing to make a change in yourself or know someone who is, look no further! I walked in nervous and timid as I had not been into a gym for around twenty years. I was greeted with open arms from the owner Brandon Kelly and the rest of the family here at Undisputed. Thinking that you are just coming to another gym would be the biggest mistake you could make. It’s not just the physical aspect that gets worked here. Brandon makes sure to work your focus and mindset as well. He has built an incredible team that supports everyone in my family like they are their own. That’s right, my two children, wife, and myself all have the privilege of being a part of Undisputed. My experience the last two years has been amazing and I can not wait to see what interesting things Brandon comes up with next. A huge thank you to everyone who works at Undisputed!

Undisputed Strength has been life changing. Going on 7 years being a member, I have created a habit of going to the gym. I’ve become healthier and feel better all around physically and mentally. I go to the gym and do the planned workout, so I don’t have to think about what to do. Great programming and great coaches who are there every step and during every class! People of all stages in life and all ages are welcome and it’s a great atmosphere! Don’t wait for tomorrow, start now! You won’t regret.

Undisputed Strength is one of the best gyms out here, hands down! 10 out of 10! The best thing about this gym is the culture, the workouts, the coaches, and the community. Undisputed Strength is the kind of gym where you feel comfortable and right at home. The coaches give amazing advice on performance. It’s not your usual gym and that’s exactly what I love about Undisputed. It’s fun, challenging, and helps you grow as an individual. I drive an hour just to work out at Undisputed Strength. BK is one of the best gym owners out there! He gives the best meal prep recipes, the best workouts, and the best advice when it comes to fasting. If you haven’t signed up yet, what are you waiting for?!

I cannot say enough good things about Undisputed. Brandon, Shae & the whole team has changed my entire outlook on health and the love for the gym. I was welcomed with open arms from the moment I stepped through the door. My only regret is not joining sooner. No matter what your goals are, what stage of life you’re in, what level of experience you’re at—this is the place to be. Each workout can be modified to your specific needs and what you put in is what you get out. Throw all your hesitations out the door & come join the best establishment and see what all the hype is about.

I’ve been at Undisputed for over 2 years and I’m in the best shape of my life. I have been active and struggled with weight my whole adult life. Since being at the gym my weight and endurance is no longer an issue. From the workouts planed out and the encouragement from coaches and fellow members it makes pushing yourself so easy. This gym is now a staple in my whole familys day. My husband and two teenage kids are members too. We all went from talking about what fast food place we want to go to, to how much weight we put up that day. If you are on the fence…. Join the gym and change your life.

I’ve tried many different workouts/gyms and none compare to the training I’ve received at Undisputed. I was intimidated to start but the coaches meet you where you are and make sure you are learning the lifts correctly to keep your body healthy.

I've been actively working out at Undisputed Strength Co for over 6 years, and what stands out most is the incredible sense of community—everyone from coaches to fellow members is supportive and welcoming, making workouts feel like a group adventure rather than a solo grind. The classes keep me fully engaged with varied routines that challenge me without ever feeling monotonous. I especially appreciate the emphasis on injury prevention through proper mechanics and movements; the coaches are pros at correcting form in real-time, which has helped me avoid tweaks and build confidence. On top of that, I've seen real gains in muscle mass from their strength-focused programs, plus noticeable improvements in mobility and range of motion thanks to the mobility drills and stretching integrated into every session. If you're looking for a gym that delivers results while fostering connections, this is it!

In my opinion this is the best gym in the area. The coaches are very knowledgeable, reliable and professional. There is no turnover in the coaching staff which says a lot about the gym. The schedule is flexible and the workouts are challenging, motivating and effective. The workouts also are very appropriate for a variety of age groups. In addition to the workouts, the nutrition coaching is very helpful. I have been a member 8 years and feel it is a great full service gym.

You seriously won’t find a better gym in the area nor one with a better community. All the negative posts on here aren’t even from anyone that has ever set foot in the place. Haters gonna hate.

But if you’re looking for somewhere where you’ll be a better version of yourself, get a good workout, be supported, and have a good time… then this is it. You don’t need to “get in shape” just to join.

I’ve belonged to lots of different t gyms in the past from x sport to CrossFit to the ymca… nothing compares to this place.

I rarely write reviews but felt compelled to write about Undisputed Fitness in Joliet. This gym has done so much for me since joining in March of 2022. Recently I injured my shoulder and thought I needed a break to rest/get better. Once my physical therapist found out I was an Undisputed member, he suggested still attending regular workouts because “they know what they’re doing over there.” Shae, Katie and the other trainers have been extremely supportive - always checking in with me regarding modifications, etc. I don’t feel uncomfortable doing modifications because the members are also super supportive. I can’t say enough about the environment at Undisputed! This gym has everything you need from lifting to nutritional support (try the Dragon Juice…it’s the best!).
