So far my experience has been great with this gym! It’s not as big as other gyms but all of the equipment is available for you to use at any time and the trainers are really great people that motivate you and help you reach your goal. I have seen a change in myself since I started coming here and I’m excited to keep on going.

Jab is such an amazing gym!! I’ve been going here for the past 2 and a half years. You won’t find a better gym with a community like this anywhere else. Joe, the owner, is the sweetest most genuine guy you will ever meet who always pushes you to do your best. My usual workout here consists of 3 rounds bike/jump rope, 3 rounds heavy bag, 3 rounds speed bag, weights and abs. These are 3 minute rounds with a minute rest. Always a great workout.

A one of a kind gym experience!! Joe has a true passion for helping people reach their goals. I have lost over 40lbs because of Jab. This place is a hidden gem that will teach you discipline, technique, and the proper ways to reach the healthy lifestyle you’ve been longing for. Sign up now!

I have enjoyed working with Joe since I started. He is a great motivator that keeps you honest. He is always there to support and encourage you meet your personal fitness goals.

Jab is the greatest no B.S gym of all time. Joe is a straight shooter and whatever your goals are, he will tell you exactly how to get there!If you want a helluva workout, and you want to sweat like never before - this is the place.

Great price, friendly and helpful staff. I was very impressed with the amount of equipment this gym offers. They are practicing social distance and keeping the equipment clean. There is a sauna and hydro massage that I enjoy after a good workout. I would recommend this gym to everyone!

My unexpected life changing surprise, JAB FITNESS! After struggling with my weight & health issues, trying diet after diet, and all different types of workouts: I had little success losing weight or getting control of my health issue (Fibromyalgia). My son asked me to join him for a day at the gym. One day trial and I was hooked! I loved it! Fabulous workout and great de-stressor. I was absolutely terrified because I didnt even know if I could do it. I was in bad physical shape. Joe set a great starter workout & diet plan and he helped me slowly improve my endurance and health until I could complete a full workout. Joe leads by example, helps guide and encourages you to do your very best. I gave up on weight loss and was working out for my health but to my amazement: I was actually losing weight. In 7 months, I am down 50 plus pounds, out of type 2 diabetes danger zone, my doctor said my blood pressure was like that of an athlete, I feel great, my fibro has been pushed into remission and Ive actually set a new goal to lose more and continue to improve my workout. A thought that I was not even considering a year ago. Super bonus is the gym is warm and friendly with a great mix of of people: kids, teens, adults, etc. Its one great place to get healthy!

Laid back atmosphere, amazing people and a place I look forward to going to.

Love working out here! The trainers are welcoming and offer challenging workouts that can work for anyone. Clean facility and all the equipment is new and in great condition.

Great workout and everytime Joe sees you he always makes you feel welcome! Best Boxing gym in town.

Jab Fitness Training is where you go to get healthy physically & mentally. There is no better environment to exercise in! Jab offers training, equipment, friends, and the best trainer around. Joe is motivational, knowledgable, and full of tips. I am so thankful to be happier and healthy. 5 months of serious workouts and dieting and I am down almost 40lbs. Thanks Joe!

Jab Fitness is the best workout I have ever had. Just the workout alone is phenomenal, but you push yourself to improve without overdoing it. It truly is the best workout i have ever done and is defiantly a full body. My endurance has increased so much. Joe is the absolute best. He pushes you without being pushy. He helps you realize your goals and get you there. Everyone does their own thing and it is the best gym and environment that i have been to. I highly recommend for any level of fitness. Joe is one of a kind.

While relatively new to this gym, I have never felt more comfortable or motivated than I do at Jab. Joe is so welcoming and motivating. He greets everyone by name and makes sure you know hes there for you. He gives you just enough push that you know you worked out, but not so much that you lose the desire to keep going. Im already seeing results and look forward to continuing to improve myself with the help of Joe and Jab.

I’ve been going to Jab for roughly 8 years. The atmosphere of this gym is unique to any gym you’ll ever be a member of. I feel like I’ve become apart of a family and enjoy every minute there. There is no better community than this one. If you’re looking to get into phenomenal shape Joe will guide you in the right direction. The boxing workout/routine coupled with his dietary advice will set you up to be in tremendous physical shape. This gym will always have a special place in my heart. If anyone is looking to challenge themselves to achieve their dream body this is the place to do so. I love everything about Jab Fitness and am glad that I found this place.

Good Place. Maxie Leonard

Joe is such a great guy! He takes the time to show you proper techniques and he can really get you motivated. Even if you are feeling a little down, hell still manages to help you find that motivation. Overall great environment, alot of people I have met there are good people and super friendly. Non judgemental place, everyone works at their own pace. I would highly recommend to anyone who is looking for a good gym.

I have been going to this gym for around 3 years now and have never regretted that decision. As a plus size woman I was honestly terrified to join a gym. Joe and the other members have done an amazing job with making me feel comfortable and most importantly welcomed. This truly is a family environment and encourage everyone to come, kids, teens, young adults and beyond. Joe caters the workout to your abilities and isn’t afraid to encourage you to reach and pass your personal goals. I promise you, you won’t regret showing up!

A great work out with very engaged trainers who clearly want to help you achieve your desired results. This is so much different than individual training sessions or going through the motions on your own.

Each visit to Jab is so fulfilling. Joe always dedicates his time to encourage his members, allowing each of us to strive to bring out our best for every workout. It’s an amazing place, with an great atmosphere, fantastic people, and amazing trainer. JAB is IT!

Amazing place. This gym has a unique atmosphere where you will find everything from motivation to support reaching your goals. The members are welcoming and Joe (the owner) engages you to get the results you desire. Can’t say enough about this place. This gym helped me acquire what I admire. Five stars hands down. A hidden gem in Naperville.

Ive been going to Jab for a couple of years now and was introduced to the place by a close friend. I was looking to get out of lifting and do something different and boxing was something I always wanted to look into. Joe, walked me through the training routine at Jab and it is both intense and fun and the perfect place to start your boxing training and cardio workout. Ive heard/seen many success stories of people seeing good change when using Joes routine and it has worked well on me as well.Overall, Jab is a great place and Joe is a great guy. The atmosphere is great and everyone is very friendly. The gym has all the basic equipment anyone would need for training. Im glad that I was introduced to this place as it makes you want to keep coming back for more!

Warm and welcoming environment. Joe (owner), hes the best! Welcomes every member who walks in the door by name, just a cool dude to know. Yeah, hell be in your ear pushing you to keep going...keep going, during workouts, but isnt that what all of us with fitness goals want? Im just say...

I’ve been at this gym for about 8 years now. I’m in better shape now than I was in high school doing track and cross country. Here, you will become part of a family. Joe (the owner) is a good friend of mine now and I can’t imagine getting my workout in anywhere else. Once you get a taste of the workout you will be addicted. Regardless of the shape you are in you will fit in just fine. I can’t express how great this gym is. Give it a try and you’ll see what I mean.

Get Work out, On hands Training.

I have been a member for over 7 years now which is a record for me. This is the only exercise program that I have stuck with for this long. I wish I had found Joe and Jab years ago! The workout is on your own fitness level and Joe is always there to help, joke and motivate when you need it most. The other members are friendly and you somehow feel like old friends with everyone, quite the contrast from those large gyms and chain fitness centers. This is a tough workout but worth every second and I recommend Jab to everyone!

Jab is more of a family than just a place to go workout, this is because of the owner Joe. He treats everyone with respect and takes time to get to know his members. The atmosphere at Jab is a relaxed and fun one. You have it all at Jab. Great owner, great members, great fun and you get in great shape.

Bare-bones, 3 mins to the next bell workouts. Accompanied by one of the best trainers in the industry. Hands down one of best gyms in all of the Chicagoland area. Its simple and it WORKS.

Been here for 8 plus years by far the best gym I’ve ever been to! Been a member since 8th grade and now I’m 22 years old. The trainer Joe really cares about your results and won’t stop Until you achieve your goals. He isn’t just my trainer now but my best friend and like a brother to me. And I’ve been in the best shape of my life. And it’s all because of him. I promise you. You won’t just gain a trainer. But you’ll gain a friend. I gained someone that I look as like he is family because we are all a family.

Joe is literally not only one of the best trainers but has such a pure soul. I’ve been coming here on and off for over 3 years. Each time I come back he always motivates me to get back to my healthy habits. Every one is super friendly, always clean and has such a welcome home type vibe. I can’t lie I love it there!

This place gave me the best results out my entire athletic career. Joe works with you everyday, especially when you are feeling down or out of it. Joe is a true genuine human being, I am proud to call him my boxing coach and my good friend.

Remember the famous line, Where veryone knows your name? Well that is the start to describe Jab Fitness. Joe Cassano, owner, sets the tone with a Hi, caring-warm smile, and uncommon authenticity. I have never had a bad work out at Jab, that is not me, but the secret recipe Joe has tapped into for fitness. More importantly, Jab offers me a place to escape the goings-on of the outside world, to get a tremendous workout, with humble people, and a great friend in Joe. After 18 mos with Jab, it entered my life at an important time; I have no hesitation putting forth the highest recommendation. Thanks Joe!

Words can not express how great Jab fitness really is. Its a great workout by far, but what makes Jab fitness so special is Joe. He treats everyone in his gym the same, he calls you by name, he encourage you and guides you in motivation and staying focused and positive. He will give help where help is needed, he works out as well. He is a great leader and inspiration to the people that know him.

There is no other workout facility like Jab! The workout is amazing. Youll never know how much of your body is utilized in the boxing process until you workout here. No frills, down to earth, everything you need in one place. And if youre looking for assistance with starting out, making your workout better, even weight training, Joe is the guy to do it. Youll never find a nicer person. He has the patience, experience, and knowledge to cater to anyones specific need. It really is more of a family environment. On the fence? Give Jab a try.....you wont be sorry.

Joe is the man! I have been coming here for 2 years and its the best decision I ever made. Highly recommended! Thanks for everything Joe!

Jab Fitness Training is a great way to get in shape. Joe is awesome! He is motivating and cares about your fitness. Best work-out ever!

Joe is awesome and Jab is a great place to work out! Joe’s a personal trainer, motivator, and friend all in one!

Joe Cassano is an excellent, uplifting, and caring guy. His knowledge and experience is helpful and unique. Such a great place to workout.

JAB Fitness Training in Naperville, IL is Bar None, the Best Boxing Gym in the Chicago-land Area.In the 9 years I have known Joe Cassano I have learned as so many others have, that Joe is dedicated to helping people succeed in both their personal and overall health and wellness goals.He provides a safe and fun environment for people of all ages to experiment with the sport of Boxing. JAB Fitness members are loyal and dedicated patrons whom come from various educational and professional backgrounds.Joes years of experience and knowledge of the sport cannot be beat.I would recommend JAB Fitness Training and Joe, as a personal trainer for anyone wanting to maintain their health, lose weight, or cross train for professional sports.

Been coming here for years. Quality place where you can just work out without all the excess nonsense I used to get at the chains where I had memberships. Also not stuck worrying about making class times. Everyone is there trying to reach a goal.

Love the gym and love Joe the owner.

5 stars hands down.

Best gym ever

Terrible guys, both brothers are rude, greedy, disrespectful people...
