Matt and Paola have really created something special with O2 Fitness and Nutrition. Organized like a team, but working and fighting like a family, O2 is a place for you, wherever you are on your journey toward better health. The gym has state-of-the-art equipment, but it’s the knowledge, patience, and support that really set this gym apart. Matt is the most knowledgeable person I have ever met when it comes to training, he lives and breathes it. He tailors the workouts to help achieve your goals, while also providing valuable instruction about nutrition, time management, and being kind to yourself.
It has truly been a lifechanging decision to train at O2. I highly recommend anyone even thinking about getting back into the gym to check out O2 Fitness and Nutrition. You will be happy you did!

O2 is truly the best!! The positive energy and welcoming vibe in the gym make me excited to go to all of the classes/workouts. Matt, Paola, and all the trainers here are extremely knowledgeable and genuinely care about you, your progress and your well-being. The classes and WOTDs are something I look forward to going to and have made me rediscover my love for the gym. If you are looking to start on or continue your fitness journey, O2 is the place to be!

I’ve worked out at O2 on and off for about 2-3 years now. There’s no place I’d rather be. Matt and Paola’s knowledge is unmatched when it comes to exercise sequence, form, and tempo. The monthly membership and personal training packages are as personalized and tailored to your needs as best as possible. Unparalleled expertise and a family-friendly atmosphere makes this the place to be in the Chicagoland area!

O2 Fitness is honestly where it’s at! I have been working out since high school and have gone through many trainers from Xsport to private independent trainers but I think it’s safe to say I found a home with some of the best people!
Paola and Matt are exceptional in absolutely everything they do; both have such unique strengths and personalities that when put together, they accomplish so much when it comes to client work. Each of them have such stellar knowledge in the fitness industry when it comes to movements, exercises and food education!
Matt has been an absolute dream to work with!! He has always helped push me beyond my limits and continues to educate and train me like an athlete because he believes in my capabilities & pushing me out of the comfort zone! He always comes in ready to push you and cheer you on as you workout; making sure that you can never fail and never say “I Can’t” but is also mindful to adjust according to your body’s needs & abilities.
Paola is absolutely AMAZING when it comes to nutritional education. She is very informative as well as helpful with food substitutes, meal prep ideas, figuring out your downfalls & how to overcome them. She is a great example of how to get things done: between being a mom, a trainer and a nutritional educator as well as the cheerleader of O2; there’s nothing she can’t do!
Mike is by far one of the most down to earth trainers, with great (funny) chats during the workouts but he trains like a beast and will push you to be one too!
Liz is beyond a sweetheart and so funny-but her HIIT classes are seriously no joke and she can roll very well in the Brazilian Jujitsu classes!
The classes here are amazing as well because they offer soooo much variety for all levels (beginner-advance). I can say for each personal training session and for each class I have attended; no two classes have been the same and continue to keep me on my toes! I appreciate the time they all have put into their work to educate themselves extensively so they could all instill the same knowledge into us so we are set up for success in the long term! If you feel like having fun losing weight, celebrating together as you hit your milestones, becoming friends with the people in the gym then this is definitely the place for you! I have looked at other places around the area and definitely nothing compares to O2! Thank you to all the trainers there for your amazing work that you do day in and day out. I cannot recommend them enough! Wish I could give them 10 stars honestly!

I’ve been training with Matt and Paola for several months now, and I could not be happier with the results. They have a deep understanding of fitness and nutrition tailoring each session to my specific needs and goals. Their knowledge is evident in their ability to explain exercises and their benefits ensuring I get the most out of every session. They are such wonderful and encouraging people. Their positivity and support push me to do my best, even on the toughest days. I highly recommend O2 Fitness and Nutrition to anyone looking to reach their fitness goals!

O2 has changed my life - I've been on my journey with Matt and Paola for almost 2 years; down 100+ lbs while not losing any muscle. My overall health has has dramatically improved and bloodwork proves it. The confidence boost is a great side effect.

Was it easy, no? No gimmicks, no shortcuts, but consistently putting in the work and being held accountable has resulted in a new life for me. Matt believed in me more than I did myself and continues to push me beyond what I think I am capable of. They flat out care about their clients and their success. I still have a long way to go and it won't come easy but with O2 I know it's just a matter of time.

You can do it if you truly want to. The O2 community is incredibly supportive to boot. I couldn't recommend O2 more.
