Tremendous place to get a workout. Friendly staff, clean facilities and quality equipment. Top notch!!

CrossFit of Naperville is without a doubt my other family. The trainers, owner, and other members in the community are all so knowledgeable, helpful, supportive, and fun! The last 5 years of my life have been the hardest in terms of physical fitness and Crossfit of Naperville has pushed my limits just enough that I have found what Im capable of. I still have a lot to learn about my body and I have a ton of goals set for myself but I am 110% confident that I will achieve all of them with the help of my CF family! A special thank you to Eric and Christina for taking everything step by step with me!

Ive been to a lot of gyms that make you feel welcome and have staff that is very knowledgeable.

LOVE this place. Work outs are challenging, the members are great, and the coaches are smart, helpful, and always encouraging. What more can you ask for in a Gym.

Great place to transform yourself. All the trainers (Eric,Christina,Bill,Rom)are very friendly on concentrates on individual performance in every class and provides immediate timely feedback to improve.The 5 elements classes by Eric were very helpful

First Box I ever joined. The workout brings the intensity I need to get my heart rate up, build core strength, learn new olympic skills, and they offer classes at 5:00am. All the trainers dummify the mechanics of the movement and encourage you to push yourself to a level that you never thought youd be able to reach. Recommend this Box to those that are near and far. Besides it is one of the original and the oldest Box.

I have nothing but good things to say about CFN. Before this box I’ve never been to CrossFit before. Never had extensive weight training outside of high school stuff with sports. All the coaches here, Eric, Christina, Bill and Rom are fantastic. They understand your needs and work with you to get your goals accomplished. I can’t say enough good things about this place. The ONLY reason i don’t go here anymore is because i moved 4 states away. Whenever i am in the Naperville area again, i will definitely be stopping by for a drop in, even just to say hello to my old CFN fam! -Ryan O.

Great place always on my list when I visit family in the area

Had a great time working out here!

I love this.
