I’ve been a member at Jab Fitness in Naperville for just under a year and honestly can’t say enough good things. The training is an absolute blast, I’ve dropped weight and I have energy I haven’t had in years. Joe (the owner and head trainer) is the real deal, he genuinely cares about every single person who walks through the door and makes you feel like family from day one.
My only regret is waiting so long to join. If you’re even thinking about it, do yourself a favor: come in, meet Joe, take the training… you’ll be hooked. Best decision I’ve made for my health in a long time. Highly recommend!!
Thank you, Joe and Jab Fitness! 💪

I would recommend anybody who either wants to get in shape, learn how to box, or just stay in a healthy condition. Jab is more than just a gym to me, it is a community of people who all have respect for each other. You meet so many new people and theres so many different types of people who come in. Joe Cassano is such a great guy and super genuine, I can go on to say he is one of the best guys I have ever met. Jab completely changed my life and made it so much better. If you are ever thinking about joining a gym come and join jab I promise you will never forget this gym, Joe(the owner), and the people you meet here. Amazing gym and I recommend you to come workout here.

Spent almost 5 years going to this gym. Due to a change in work/school schedule I had to make the extremely difficult decision to leave. Really dope place, you get to work out in the fresh air when the garage door is open, perfect amount of people, rarely ever overcrowded, Joe (the owner) is always down to help you out with nutritional advice, form, or any questions or comments you have. Most of the things I’ve learned that have helped me along the way have came from his feedback. Good guy to talk to, never intrusive during your work out. Love this place.

Where do I start. Jab Fitness is the place to be. Not only does it have a family feel but also a place where you can work at your own pace as well. The owner Joe is someone who will be your right hand man throughout this whole process. I started with zero experience of boxing and in only a little bit of time I have grown so much. Not only has his workout contributed to weight loss but also retaining muscle throughout the process. If you are looking for a place to get out of your comfort zone and finally finding a place where “you belong” look no further. Not only the best boxing gym I have been a part of but also gym in general. Joe is the man with a plan!

Owner joe is a FANTASTIC person, not only is he a great coach but will always watch out for you and make sure you have a good experience every time you walk in the gym. Always full of good energy, and good vibes. Would recommend jab to those looking for a good boxing gym or just a good gym atmosphere in general. 🥊

Working with Joe is very incredible. He is a very knowledgeable and skilled coach. He closely monitors every move you make during your training and corrects any errors. I started a month ago and have already seen weight loss. It's a terrible 30-minute workout, but it can change your life. Joe is a really kind and inspiring person. You get strength from his words of admiration in the middle of the workout. It is just amazing and no nonsense gym.

At a time I was looking to take my fitness to the next level and make a change, Jab Fitness did just that and changed my life forever. Joe is the best! I had no boxing experience. My first day was tough, but I could tell I had someone who was going to truly help me achieve my goals. Joe did just that. He really cares and wants to see you be successful. He continued to work with me, teach me new things and push me to new limits. Not to mention, I never wanted to leave. If I wasn’t training, I was having great conversations with Joe or other members. I mean who gets their name on a chair at a gym! It’s such a great environment and there are so many great people that I have created lifelong friendships with. Joe is like family to me! I appreciate him believing in me!

There is no place like Jab. Coach Joe is an expert on training members of various skill levels, and does so with a warm, encouraging passion. After several years of training here, I can say without a doubt it is the best 30-minute workout in town.

I struggled for years to find a gym that was a good fit and that I would actually go to- I am so happy I found Jab! I’ve been coming here for several years now and not only is it a fantastic workout, but also a great family-like atmosphere. Like nowhere I’ve ever been before. Joe is Jab Fitness and he is the most inspiring and encouraging person. And just a great guy all around. He treats everyone as an individual and helps you tailor your work out. It’s like having a personal trainer for no extra cost.

Before coming to Jab Fitness, I had tried several other gyms. Most places made me feel out of place and self-conscious. Jab is different. Firstly, Joe greets every member by name as soon as they walk through the door. It makes you feel like you belong; part of something. The members are from all walks of life and represent the full spectrum of the fitness journey. The whole atmosphere is one of encouragement and support. Joe will push you to make sure you're working as hard as you can, and he'll keep you accountable, but you'll never feel judged or intimidated

I have been with Jab Fitness for over 5 months and I have nothing but praise. For statistics, I am 5'9", I started at 29% body fat and 216 lbs. and now I am 19% body fat and 179 lbs. and counting. The atmosphere provides a "you are always welcome" vibe. Joe, the owner, is a great mentor in the sport of boxing and will do all the exercises with you until you are comfortable on your own. All the members are courteous & accepting of anyone with no feeling of being judged. If you are looking for a local boxing gym in the Chicagoland area that isn't traditional "big box" for an affordable price, this place cannot be beat!

JAB Fitness was the beginning of my journey into a healthy lifestyle and the start of ultimately losing 65lbs and counting. Before JAB, I was overweight and tried a variety of physical activities that lost my interest quickly. Once I found JAB, I was hooked. Joe, the owner, is supportive and encourages you to do your best without the unrealistic expectations and the pushiness. Overall JAB has changed my life for the better. If you are tired of struggling with weight loss and want to become healthy, look no further!

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 didn't 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 I've 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. It's one great place to get healthy!

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 he's 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. I'm already seeing results and look forward to continuing to improve myself with the help of Joe and Jab.

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.

There is no other workout facility like Jab! The workout is amazing. You'll 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 you're looking for assistance with starting out, making your workout better, even weight training, Joe is the guy to do it. You'll never find a nicer person. He has the patience, experience, and knowledge to cater to anyone's specific need. It really is more of a family environment. On the fence?

I've 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. I've heard/seen many success stories of people seeing good change when using Joe's 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. I'm glad that I was introduced to this place as it makes you want to keep coming back for more!

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.

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.

Remember the famous line, "Where veryone knows your name?" Well that is the start to describe Jab Fitness. Joe Cassano, owner, set's 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!

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.

Joe's 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.
