Jesse Devlin-Whitworth 2 years ago

Fantastic experience: For many years I had thought about doing CrossFit but was always too intimidated to try. Then I was recommended to try CrossFit Fairfax, and the past few years have been amazing. They breakdown everything in a way that makes CrossFit accessible and the Coaches really work hard to ensure members of all abilities get the most out of every workout. They also give us the individual attention necessary to check form and give us advice. The members are also great and super supportive, overall it’s just a great box.

Fantastic experience: CrossFit Fairfax is awesome. The caliber of the coaching is top notch and coaches and members alike are just the kindest people. All levels of athletes (or non athletes) welcome here. I had a really hard time finding a gym where I could bring my son and I’m so glad someone recommended CF Fairfax. A truly non-intimidating and family friendly environment. If you’re wondering if this is the right place for you— it is.

isaiah nunez 2 years ago

Fantastic experience: CrossFit Fairfax is the best find in NoVa! As my first time getting into CrossFit I was a little nervous at first. However, Julie and all of the coaches were more than helpful with making me feel at home, helping me to develop the proper form and technique as well as helping me reach my personal fitness goals. I highly recommend CrossFit Fairfax!

Fantastic experience: I joined CFFX after moving to the area and with experience from another box.

Fantastic experience: I’ve been a part of the family for over 10 years. You will never find another fitness facility that has a more educated, sincere, and fitness-intelligent staff. CrossFit is a game changer only if you have the right team to help you incorporate it into your life.

Sharon Kim 4 years ago

Fantastic experience: i love this place sooooooo much. everyone is so nice and inviting and i PR literally every single time we lift i don’t know what’s happening

Nate Stafford 5 years ago

Fantastic experience: For anyone else like me, traveling in the area and looking for a great gym to drop in to, this is it. I have dropped in to a half dozen gyms in the DC area, and CrossFit Fairfax is by far the best I've been to yet. Additionally, in a city where drop-ins are ridiculously expensive, their pricing is very fair. The first drop in is free, and you can do a whole week for just $50. Great programming, engaged coaches, and an excellent space.

Matt Harris 5 years ago

Fantastic experience: We joined CF Fairfax three years ago and it’s like a second family. Amazing and supportive community of people who will support you, push you past your self imposed limits, and have a ton of fun along the way. Great programming, crazy-qualified coaches (some of the highest certified CF coaches in the world probably), and a fun sense of family. Love love love this place.

Chelsea Sowder 6 years ago

Fantastic experience: Absolutely love Crossfit Fairfax. Started working out here about 2 months ago and every workout I had here was customizable and challenging. I don't think I ever went to Crossfit Fairfax without learning something new. All the coaches were personally invested in improving my fitness and strength while ensuring that I was performing the workouts safely and correctly. I only left this place because of a military PCS and even then one of the coaches helped me research CrossFit Gyms in area to which I was moving! Highly recommend.

Jessica Guinta 6 years ago

Fantastic experience: CrossFit Fairfax is the best community I've ever been a part of. Whether you've been doing CrossFit for years or you're taking the leap and trying something new, you'll find that CrossFit Fairfax is your new home away from home! Jeff, Julie, and all of the other coaches are very supportive, motivating, and experienced to help people of all fitness levels achieve their goals :)

Tyler Costello 8 years ago

Fantastic experience: CrossFit Fairfax is an awesome box. Lots of competitive athletes and an overall great community feel. I started at this box and won't be going anywhere anytime soon. When I first started I had never done a lot of the movements but with really good coaching I was up to speed in no time. I recommend this box to anyone interested in CrossFit. Whether you're a beginner or a competitive athlete, this is the box for you!
