I had always heard about CrossFit from friends but it took an instagram advertisement saying "6week challenge" for me to finally try it and boy I'm TOTALLY ADDICTED!! I run Marathons so challenges excite me. So i followed a simple high protein nutrition plan given to me by Heather Refenes (who is amazing btw!!) for 6 weeks and worked out about 3-4 times a week and i ended up losing 4 percent body fat AND gaining 3 pounds of lean muscle in the first 3 weeks!! I couldn't believe it! On top of that i can now do PULL-UPS which was the only thing i physically could not do before i joined CF and i am squatting 135lbs now which is a huge jump and deal for me (i weigh about 121 pounds). In short, i am stoked with the results!! The gym is brand new, super clean and makes you want to workout as soon as you get there! The plan for me was to stay for 6 weeks but i love it so much now that I am joining in!! Being a UChicago mom, 5:30am CrossFit works out really well for me and gives me energy throughout the day. The coaches are all so helpful, motivating and fun, i look forward to training with them (John, Tanya, Tim, Heather, Matt and the guy who got me hooked on this, JP!!) every single time! And of course the SugarWOD community; i never thought logging in workouts and giving fist bumps would be something i would get into but i have realised that it actually pushes you to want to do more and get a good score every time, it's the definition of healthy competition. So for all you crazy workout junkies like me who want to keep challenging your body in different ways and also people who want to lose weight/gain muscle but find it hard to go to the gym and workout on their own, THIS IS THE PLACE FOR YOU!! (And NO it will not make you BULKY/BIG ladies, it will only make you into a GREEN LEAN MACHINE :)). Highly highly recommended to everyone! read more

I just completed a six-week Challenge at CrossFit Factorial and found it to be a great place to improve fitness and make positive connections! This Box is incredibly clean and organized, with equipment that is in wonderful condition. The coaches are great, and they did an exceptional job modifying the workouts for me (around a pre-existing injury). I was also impressed with their focus on technique over quantity or weight - as it allowed me to push myself in a safe, yet challenging, manner. I made noticeable improvements in my shoulder strength and stability, which proves you can build strength quickly and safely with these workouts - whether Rx or modified. I also participated in a six-week weight loss challenge. While I was initially hesitant, I did end up losing 17.5 lbs in the six weeks!! The program supported this loss through the assistance of their knowledgeable nutritionist, Heather (who provides personalized nutrition planning and individual check-in) - as well as participation in the daily workouts, of which I completed three per week. I was most excited to learn that of the 17.5 lbs lost - only 0.7 lbs was muscle! That much weight loss w so little muscle loss is a huge win in my book!! If you want to improve your eating and fitness, and would like help getting started and maintaining your motivation - this is a great program to consider! In closing - I must mention the owner, JP. Along with being an extremely knowledgeable coach, he is also a compassionate, solid, and generous human being who graciously took time to answer all my questions and concerns. (He even took time to help me with all my geeky technique questions!!) I am very appreciative. I am very impressed. I whole-heartedly recommend CrossFit Factorial if you want to improve your fitness, your health, and your sense of well-being! Give it a try! read more

" As they say: it takes a village to raise a kid. To me : It takes a community to help a person become healthier and to loose weight. It became my reality when I finished the CROSSFIT FACTORIAL 6 week challenge and was able to achieve my goal of becoming fit, healthier and lose 20 pounds. My community was composed by JP who gave me all the directions regarding all steps of the challenging and helped me be familirized with the gym. Heather - the queen of nutrition - guided me to all the maneuvers related to eating clean, healthfully and wisely. She was always on top of her expertise...sending me emails, text messages full of encouragement, coaching and motivation. Even designing a program for a vegetarian like me. The classes were so dynamic....energetic and very creative. NEVER BORING ! The personal trainers were ALWAYS alert, motivators and attentive to educating me how to use the apparatus and helping me to develop the right form of exercising. Another fantastic part of this experience was the class participants...that generated a very helpful and friendly environment...since my first class I always felt welcomed and a great sense of belonging took place. I attribute my success to the hard work and dedication that I experienced from all the elements that make CROSSFIT FACTORY a fantastic community - a place where healthier transformation can happen. If you want to achieve success - come and become part of this village of healthy, fitness and special people. " read more

I came across CrossFit Factorial on a Instagram ad. The ad stated a 6 week free trial of gym access including accountability coaching, meal planning, and access to all the amenities a member would have during the duration of the trial. It seemed interesting and I had never done Crossfit before, so I signed up. Upon the consultation, I was explained everything clearly as far as how classes went, what to expect of the gym, and the conditions of the free trial. Everything is really clear and JP and Heather were great and straight forward with the business. The classes were extremely helpful to a newbie like me, having never tried Crossfit before. Every class is instructed well, and the techniques of the workouts are explained before the workout but are also corrected during the process of the session. The environment is pleasant, clean, and is a great atmosphere overall. I enjoyed my trial, and would definitely return as member. I would definitely recommend CrossFit Factorial to others in any stage of athleticism that they are in. read more

I came to CrossFit Factorial through the 6 week challenge unsure of how my experience would be (I had never done CrossFit before) because I wanted to make a change. I had injured myself a few years ago, and have never really been able to be regular about lifting since. One of the many warnings I had heard about crossfit gyms in general was the possibility of getting injured considering the high volume of complex lifts entailed. The coaches at CrossFit Factorial helped me put those concerns to rest by consistently watching my form, teaching me proper technique, and helping me scale and modify workouts appropriately for my flexibility limitations and strength levels. I decided to stay on past the 6 week challenge because of the coaches and overall environment. Even though I'm usually one of the last people to finish a workout, I always feel supported and encouraged to continue coming. If you're curious about CrossFit, definitely check out Factorial! read more

I had never attempted Crossfit before participating in Crossfit Factorial's 6-Week Weight Loss Challenge. Their personalized nutrition plan, coaching, and assistance/demonstration understanding all of the new Olympic powerlifting moves my body had never done before was exactly what I needed to remain motivated about a healthier lifestyle. In the end, I did not meet the weight loss challenge, but that was really by my own doing. I agreed to extend my membership past the 6-week challenge because their class and instruction style really works to keep me from getting bored or lazy at the gym. It's never too late to improve on your wellness, even for the first time. And if you're already familiar with Crossfit in general, both the instructors and members are all super positive and supportive, who want to help you succeed. It's a great place to get physically fit. read more

I've been enjoying my membership at Factorial for 4 years now. It's clean, well run, great coaching and I love the community. But this review is about the nutritional counseling I have been receiving since December. Amanda has made it easy and flexible and I've seen better results than I expected. I've lost lost weight and fat and gained muscle, and my lab work has improved in 3 months. I've added more healthy foods, but have not felt like I'm sacrificing. This is a sustainable way of living and keeping my health on track as I age. Come for the workouts, stay for the nutrition! read more

I joined Crossfit Factorial with zero knowledge about crossfit workout. I thought it was gonna be hard for me but the coaches made everything doable.

A lot of class schedules that fits my varying daily routine. Facility is great! Clean, nice bathrooms, I don't have to worry about going straight to work. Members are awesome! They motivate you to push your self up to the last Rep. Also, really nice music choice/sound system. read more

Great experience and excellent coaches! I signed up for a six week weight loss/body fat challenge at the beginning of the year. I received consistent updates, motivational text message, and diet tips weekly. The classes were challenging and fun. I found out two weeks into the challenge I had a torn rotator cuff. Despite my physical limitations, the coaches worked with me, gave me modifications, and we're extremely supportive. I strongly recommend Factorial for any living the Skokie, north Chicago, and Evanston area. Great Community! read more

We dropped at CrossFit Factorial a couple of times. When we arrived we received a warm welcome. The coaches - especially Tim and JP - are super friendly and supportive. The gym is very well equipped and has a separate OpenGym area which allowed us to follow our own programming. It is also the cleanest CrossFit facility we have seen. I can absolutely recommend this gym! read more
