The XS CrossFit location in Parker, Colorado was my first exposure to CrossFit in 2017. I was looking to break the mold of going to a Globo Gym and needed something different. XS CrossFit's On Ramp Classes allowed me to be introduced to movements and lifts that I have never done before so I would be ready to attend regular classes. The coaches have been absolutely amazing, giving modifications (if necessary) to any movement that I cannot do. I always walk away knowing I got a great workout! The schedule is extremely accommodating with classes throughout the day, along with my favorite classes, Barbell and Open Gym. Also, my two daughters attend the Teen classes. XS CrossFit is now consistently a part of my day and I have met so many people that have become great friends. It is definitely a "leave your ego at the door gym" and comes highly recommended to someone who is looking for a relaxed and fun fitness atmosphere! read more

I have been a CrossFitter since October 1, 2011 when XS opened it's doors. At the time, Alex had to talk me into it. Since then, I have learned more about my body, what it's capable of, and how my mind can literally talk it into anything with the help of Alex's coaching. He has been an awesome mentor and friend! If you are looking at other gyms in the area, keep in mind XS is the only one with a track and a coach in the gym at all times! Alex is super chill and lets you do additional strength training as long as you let him know when you're coming in and it doesnt interrupt a scheduled class!! Plus, we have a KIDS program too!! Great gym, but, in fact the best part are the athletes that make up our community. We have regular barbecues and a cheering section at every competition we go to! We would not be the same without each and every member who adds their own little spice or sugar :) read more

This place is great for those that are looking to get into Crossfit for the first time. The owner Alex is down to earth and will not push you into a membership unless you enjoy it. The program new members go through is called the "on ramp program" it take you through all the movements and lifts you will use. Even though the on ramp program is a intro class you will get a workout and it will use muscles your not used to, so please don't think its just a walk in the park if your just starting out. Everyone there is very welcoming and there is no judging just regular people looking for a great work out. They are fairly priced and Saturdays are free, Saturdays are fun because its exercises that take team work. If your just starting out or looking to take your workout up a notch this is the place.. read more

I have been a member of XS Crossfit since 2012. I have tried different gyms throughout the Denver area. XS Crossfit is by far the best. We have grown through the years. We have added more space, equipment, and a lot more members. Depending on when you come, the classes average in size from 5 to 20. We still have a 400 meter track and plenty of space to workout outside. Yea, sounds like a sales pitch doesn't it? Needless to say, I stand by my word that you won't be disappointed. The coaches are knowledgeable and will answer the questions you have. The members are personable and friendly. And the crossfit culture is alive and well. We have a 10am class on Saturdays that are free so if you want to try something that may be a life changer, head on down. read more

Ive been crossfitting at XS Crossfit for over a year now, and must say that since I moved from NY in 2009 - this gym has provided the best across the board experience for me when it comes to improving my health. All of the people are absolutely amazing, keeping you motivated and excited to come back every day. The trainers all know how to get you functionally fit and keep you safe all at the same time! I came into Crossfit only knowing how to bench and now I can perform all of the olympic lifts correctly and safely, and my body composition and ability to recover have improved ten fold! Highly recommend joining this gym as the prices are incredibly reasonable, roughly half of what you would pay in most boxes in Denver! read more

I've been a member of XS Crossfit for over 12 years. Not many gyms can boast such long-standing members, but that's because not many gyms provide the value, results, and community found at XS Crossfit. The coaches are well-trained and able to lead people at all ages, fitness levels, and abilities through every workout in a fun and encouraging, yet challenging environment. I highly recommend XS Crossfit whether you're looking to start working on your fitness goals, maintain a challenging workout program, or just make some new friends who will encourage and inspire you. Stop by for a fun, free Saturday morning class (10 a.m.) and give it a try. All you have to gain is better fitness and health! ​​​ read more

I had a friend introduce me to XS Crossfit in Parker, CO. What a great place to workout! With the addition of the second building, there is plenty of space, lots of bars and equipment to do everything from lifts to wall balls to practicing your double unders. There are classes for all walks of life, from beginners to kids to advanced. I will agree with other reviews that the coaches are exceptional and will take the time to assist with form and function. An added bonus is the people that I have met and the friendships that I have acquired. An added bonus is the 400 M outdoor path on the property. If you are in the area, stop by and meet the extraordinary folks at XS Crossfit. read more

I joined XS Crossfit 3 weeks ago and I am hooked! The workouts are hard but amazing. Most Crossfit gyms do not have a class around lunch time, so the 1:30 class here is perfect for me. Alex has done a superb job of demonstrating the movements without making me feel outrageously like the new person. Every single person at the gym has been welcoming and I like how incredibly encouraging they are. It is awesome that you can see the WOD online before you get to class and I can track my progress. The gym is particularly clean with plenty of space and equipment. I even got to enjoy a 2 mile run on their woodchip track last week. XS Crossfit is the best Crossfit gym in Parker. read more

I started going to XS Crossfit in February 2013 not knowing what I was getting myself into. I had been involved with gymnastics and sports most of my life so I was by no means a total fitness "newbie", but man did XS challenge my mind and body in ways general fitness never had before. I've always wanted defined abs and a killer butt and I can now say I'm extremely close to having both!! The trainers at XS are amazing and truly care about each individual member and their fitness goals. Class times throughout the day and the strength training program that Alex, the owner, runs make XS the best crossfit gym in the Parker area. read more

I started XS Crossfit two years ago. When I started, I was in my late 50's and thought there was no way I could do this. Alex, the most incedible instructor ever, had modified because I am not as young as I use to be. As time has gone by, I am getting better and stronger each week. I cannot do what the younger ones are doing but I am better today and healthier. Everyone is encouraging and we are always working together to get better. I am addicted!!! read more

I joined XSCrossfit in 2013, I was 50 yrs old, out of shape and overweight. I always felt like I belonged to this crossfit family. I was well coached, encouraged and pushed to accomplish things I never thought I could do! I am still well coached 2 years later, still encouraged and still pushed. It is a great group of people, and a great place to make positive changes. The coaches are patient and knowledgeable - come visit!!! read more

I joined XS after a good friend told me about it. I was unsure what to expect from the classes as far as difficulty and challenge - but I have been very pleasantly surprised! The classes accommodate all levels of skill and I have truly enjoyed the experience thus far. I joined with the goal of building functional strength, mental toughness, and in hopes of extending my Vo2 curve . XS is making all of that happen! read more

This gym and their coaches and owner (Alex) is great. They all take pride in your performance and keeping a safe fun and encouraging place to workout in. They have open gym times and scheduled classes as well as kid-care or what ever you want to call it for parents. They have on-ramp classes for those looking for a new activity or simply wanting to dip their toes. read more

The atmosphere is fantastic made possible by the great coaches, especially Alex Etzen. I have met some fantastic people at XS who push me in my work outs every day. If you are looking for a good box XS is well worth the look. read more
