CrossFit® Loop: Opinions

Fantastic experience: Great open floor plan. Everyone is very welcoming. They have a wonderful kids room where you can actually get a workout in and know they are safe. The coaches are very knowledgeable and will keep you on your toes. Their programming is really good. They have a couple of options for open gym which is great ( I am a busy mom of three and sometimes cant make the scheduled classes). I would definitely recommend this place if you're looking for a permanent gym and/or in town and looking for somewhere to drop in.
Fantastic experience: I would recommend this gym to anyone. Awesome positive atmosphere.
Fantastic experience: Absolutely love this place. Mostly have attended Jacobs classes whom is outstanding. I look forward to the beat down and it keeps me coming back for more. The people whom train in the classes are supportive, helpful and kick arse!
Fantastic experience: I drop in to CrossFit Loop whenever I am in the area. The coaches are always welcoming. They find a good balance between pushing people to challenge themselves with scaling movements or load to meet people where they are at. I highly recommend CrossFit Loop.
Fantastic experience: Was visiting from Chicago and dropped in with a friend. Very welcoming and I felt super comfortable being there.
Fantastic experience: Love the size and program. Good mix of cardio, gymnastics, and lifting.
Fantastic experience: Dropped in a few weeks ago and had a great experience. This is my first stop the next time I'm in Castle Rock.
Fantastic experience: I was able to drop in twice during my visit to Colorado and both times it was an excellent workout with a great coach. The facility is top notch and the people were very welcoming. I will definitely be back the next time I visit CO. Thank you for a great drop in experience!
Fantastic experience: Fantastic classes! Hard but invigorating, with supportive and helpful instructors. The facilities are very nice as well!
Fantastic experience: Just a friendly FYI, sitting outside looking at your business I noticed your American flag that faces outside is ganging wrong. When your flag hangs vertical, the stars need to be on the left. In windows you could have two flags on top of each other facing in the business and one facing out but with the stars on the left. Thank you and keep being a great Castle Rock business!
Fantastic experience: WOW! I wish I could give more than 5 stars. I’ve never felt so welcomed and included as I have here, even from day 1 testing out their gym/classes. The Owners are AMAZING passionate people, the coaches are so knowledgeable and truly care about your performance, the members are some of the nicest people I’ve ever met. It truly has a family vibe to it. I can’t thank them enough for having such an amazing facility and group of people!! AND the workouts are extremely intense! 11/10
Fantastic experience: I hadn't ever been to a crossfit gym (or any gym) before I started here. The coaches are down to earth, super knowledgeable, and eager to help anyone that shows up. I'm overall very impressed with the positive/ welcoming vibes of this place and would happily recommend it to anyone interested. 100% an asset to the Castle Rock community! Thanks CrossFit Loop.
Fantastic experience: The day after I inquired about dropping in on the Loop website Korby contacted me. His mood was incredibly welcoming and sincere. Once I arrived at the gym, that experience carried through from the other trainers and members. Great programs, incredible facility and outstanding members and feeling of community. Way to go Team Loop. Thank you!
Fantastic experience: Had a great visit to CrossFit Loop. The coach did an incredible job managing a large class (20ish people): a full warm up specifically related to movements in the WOD, a clear overview of the workout, offered scaling options and modifications, and providing direct feedback on movements to almost everyone in the class. Probably in my top three drop in experiences from a coaching standpoint. Highly recommend.
Fantastic experience: I have been to dozens of boxes in my travels in the last 7 years, and this place is one of my favorites. I have never seen such an engaged, kind, and experienced group of coaches in all my years of CrossFit. All levels of experience, but a great family vibe through and through. And they will kick your butt in the WOD, too!
Fantastic experience: This is the best crossfit gym! The Owner is so fun, energetic, and fun to be around! The coaches are always willing to help. Super knowledgeable and will help you with your form! I would recommend this gym to everyone!!
Fantastic experience: CrossFit Loop is fantastic for beginners like me. I've only been going to CrossFit for a few weeks, and every coach is very focused on the new athletes, providing guidance on the correct form for each exercise. All the experienced athletes are also super friendly and supportive! It feels like a great community!
Fantastic experience: After several visits spanning a few years, I can say this is one of the best CrossFit’s I’ve ever attended, and I’ve been all over the world. I just wish most were even close to as good as this! The community is incredibly welcoming, coaching extremely passionate, detailed and knowledgeable and the workouts are focused, appropriate and challenging. I can’t recommend this place highly enough!
Fantastic experience: My wife and I were looking for a gym and came across this gym by a member referral. Wow! It's the best gym. It has all the goodies other boxes have, but it has a family atmosphere that is very caring and encouraging. As you can tell by the other reviews this is the gym to go to if you live in or around Castle Rock. I could go on and on about this gym but I would just come try it out yourself and see what all the hype is about.
Fantastic experience: Spent a week working out here while visiting family in Parker. Korby, his coaches and the members are awesome. Everybody made me feel right at home! Members are super friendly, went out of their way to introduce themselves and cheered me on as I struggled with getting use to the thin air of Denver. The programming is great; pushing you like crossfit wod's are designed to and the movement tips from the coaches are excellent. I felt like I was in my home box. If your passing through town or looking for a new box, I would for sure spend some time here. The box is huge with loads of equipment. Thanks again Crossfit Loop for welcoming in to your community while here. Can't wait to come back!
Fantastic experience: This is the second box I’ve tried visiting Colorado and it’s absolutely fantastic. We visited for nearly 2 weeks and they welcomed us like we were part of their family. The facility is big, clean and has plenty of equipment for everyone. Korby, Ann, Matt, and all of the members and coaches were extremely welcoming, accommodating and genuinely interested in us, our training, and our experience. Super laid back yet competitive as crossfit should be. If you’re in the Castle Rock area, 100% drop in for a WOD. We cannot wait to come back!
Fantastic experience: Spent almost 2 weeks visiting this box. Korby, Joby, Matt, Anne and all the other coaches were very welcoming and accommodating. They really made it feel like our home away from home. The gym members were all very nice and friendly. The box was a great size, clean and had a ton of equipment. I would highly recommend dropping in if you’re in Castle Rock.
Fantastic experience: Love everything about CrossFit Loop. The coaches are fun, motivating and knowledgeable. That helped me get through really challenging workouts feeling accomplished and proud. The space is clean, welcoming and has the extra amenities like a shower if you need a quick rinse after your sweat. What I loved the most is the sense of community and how included (and supported) I felt working out there the first time.
Fantastic experience: I travel a lot and drop into boxes all around the country. WOW! CrossFit Loop is by far one of the best boxes I have visited. The staff was welcoming, committed to form and safety, and did a thorough group warm up of mobility and movement review. I was welcomed into the fold by coaches and athletes alike and by the end of my WOD, I felt like I train with these people all the time. What a great community. I'll definitely be back.
Fantastic experience: CF loop is a great gym! The owners and coaches are supportive, motivating, positive and encouraging. The owners listen to the needs/wants of their clients, adding more equipment, making tweaks in the gym, etc...for me personally, I like that CF Loop is involved in the local community and supports other small businesses as well. If you are hesitant to try cf, give it a try- it's a non- judge mental group and you will have fun too!
Fantastic experience: CrossFit Loop is the best CrossFit gym in Colorado. The owners care about their members and are constantly upgrading the facility and responding to their members needs and requests. The coaches are some of the best in CrossFit and the member community is welcoming and friendly. When you're at CrossFit Loop, you feel like you fit in from your very first day regardless of your ability; it's the perfect place to start CrossFit, maintain your fitness and develop your competitive skills.
Fantastic experience: CrossFit Loop is amazing! The trainers are top notch whether it's your 1st day or you're training for the games. The workouts are scalable for every fitness level. Everyone is very welcoming and it feels like home the minute you walk in the door. The owners are very personable and they truly care about every member. Give it a try and you won't be disappointed.
Fantastic experience: Literally the most fun and welcoming atmosphere I have EVER experienced at a Crossfit box. Our coach Joby was incredibly knowledgeable. He and the owner Korby made sure we were able to understand the movements, do them safely, and adjust anything we needed to (Crossfit is not my normal workout). The group we worked out with all knew each other well and had different levels of abilities and everyone was SO INCLUSIVE and supportive. There are definitely some hard core athletes and the coaches all have a massive amount of knowledge/training, but it felt accessible (while still giving me a hard workout) for a beginner. I will absolutely go back anytime I can make it down to Castle Rock- good vibes only at CrossFit Loop. I left with a smile that will carry through the whole day!
Fantastic experience: I love Crossfit Loop for the members that have made this place a fun and friendly environment. Crossfit Loop is accessible to the first time athlete and at the same time is made to produce athletes at the highest level. This is the best affiliate I have ever been a part of. Thanks Crossfit Loop athletes and coaches!
Fantastic experience: We moved to Castle Rock in April from Colorado Springs. When we asked the owner of our Crossfit home of a couple years one of the gyms he suggested we check out was Loop. From our first contact with Korby, we had the feeling that we found our new Crossfit home. We did check out a couple others and Loop was overall a better choice for us. Loop has welcomed not only us but also each person that has dropped in since we have joined. Great equipment, great coaches, and great athletes/members = Crossfit Loop!
Fantastic experience: Crossfit Loop is one heck of a crossfit box, and in my not so humble opinion the best in Colorado. It's what every box should be, with plenty of high end equipment, rig space for days, and the best staff I've ever come across. They make sure each and every class is all about a good time with great people, safe movement, and workouts where the theme is suffering together. So if you're looking for a new place to workout, or just need to get your WOD on during a road trip Crossfit Loop is THE place to be!
Fantastic experience: From the owners, to the coaches to the members this box is amazing! It is definitely a place of community, everyone is so welcoming and caring. Coaches go above and beyond to make sure every athlete is confident in what they are doing and make each WOD accessible to all fitness levels.
Fantastic experience: Best Crossfit Box we have ever been to. Korby and Anne truly care about there athletes. Everyone here is welcoming and encouraging. I look forward to coming and getting my WOD in daily. This is NOT your typical box, there is not that feeling when you first start or ever. Loop is definitely like a second family. They have phenomenal kids & teens programs. The whole family can come in and workout. Great coaches that want you to succeed.
Fantastic experience: I have been working out for over 35 years and recently started cross fit. Crossfit Loop is by far the best gym I have ever been to. The coaches here are amazing and the atmosphere is friendly and motivating like nothing I've experienced. If you are considering cross fit this is the best and only place you should go!
Fantastic experience: I never really liked the crossfit scene. It always seemed to me like a click that I was never apart of. I am also not very keen on cardio. However my wife wanted to check it out, so we did. Right when we walked in Korby greeted us and was very friendly and open. He also introduced us to his wife and other instructors, along with other members that were there for the workout. Everyone was very friendly. They have some great instructors that ensure you are doing the exercise correctly and no pushing you to do heavier weight. I have been going for only a month and still enjoy going. It is also great for teens. My oldest son goes and the classes for teens are at the same time as the adults which is very convenient. Great family oriented place to get a great workout.
Fantastic experience: Dropped in as I am traveling for work and was welcomed graciously by the owner Joby. Ample parking space for my box truck and great atmosphere. Felt like a true Crossfit box. Coaching was specific to each person and all the athletes were super cool and welcoming. One of the best boxes I've dropped into yet. Next time I swing through castle rock I'm definitely hitting it up again. Trust me, this is the box to work out at!
Fantastic experience: I emailed Korby through the website at 730 pm on a Sunday evening to drop in on monday 730 class. He replied that night extending an invite. At the gym, I felt like I had purchased some sort of premium membership as Korby gave me a full tour, introduced me to the coaches and athletes. The main floor is spacious and well maintained. I like the separate area where an athlete could put in a little extra work without worrying about interfering with the wod Everyone was friendly and welcoming. JT coached the WOD and took time to discuss the movements with me to make sure I was comfortable and so he could be sure I was going to be safe. Great warm-up, a short strength session and then the wod. If I lived in the area, no doubt I would noon loop. I don't know how this could be better unless there was free beer.
Fantastic experience: I never was interested in crossfit, never really wanted to do it. But my husband kept pushing me to try it... so when we moved to Colorado recently, I decided to try Crossfit Loop. I'm so glad I tried it, I love it there! The people are so great, so friendly and welcoming. We have met some great friends. The coaches are so helpful and knowledgeable. I'm new to crossfit so I have tons of questions, they are always eager to help and push you as they see fit. I couldn't have asked for a better place to start crossfit. Thank you so much to all the coaches at Loop!
Fantastic experience: The best crossfit gym I've ever been to. The coaches and owners are fantastic and so knowledgeable. Everyone here is friendly and welcoming. I am so happy to have found crossfit loop and my crossfit family!
Fantastic experience: By far the best CF box I've ever belonged to! Super friendly staff, great atmosphere, and great coaches. Fantastic kids club too, if your little ones are a factor in getting to the gym.
Fantastic experience: I miss being “in the Loop”—I relocated, but maybe Korby (the owner) will, one day, open a gym closer to me. Knowing Korby from another gym before Loop’s inception, he was always high energy and welcoming and still is today. The trainers he stocked the gym with are excellent (they’re all good, but spend an hour with Joby and he’ll, unconventionally, blow your mind). The gym he built focuses on community and, in some way, feels like the Cheers sitcom theme song. The place is well organized for the space and whenever something could be better, Korby keeps reiterating to do so. The kid’s area is wonderful and the place is clean. They even have towel service! Get Looped in—you’ll be happy you did.
Fantastic experience: My husband and I joined crossfit loop a couple of months ago and have been addicted ever since. The coaches and athletes here are so welcoming and take the time to get to know you. Workouts are intense and make you want to come back.
Fantastic experience: Everyone there is very welcoming!!! I was nervous to begin CrossFit again after a 4 year break. I have injuries that require modification, and the coaches do an amazing job of working with me, but not making me feel inadequate. I have so much fun while I am there with the coaches, owners and other athletes, it has become a home away from home in a short period of time. My two kids love it there as well!
Fantastic experience: Every day I leave the office I get a.chance to connect with people I enjoy and get better every day (in other words get my butt kicked). The coaches and owners do this for the right reasons and really embrace folks that want to challenge themselves. Stop in and see for yourself. I love my daily dose of crossfit at the loop. Look forward to seeing you there.
Fantastic experience: Coach Cortney is awesome! My 5 kids can’t wait to get to class and improve. I have seen them go from being uncomfortable and awkward to confident and more in control of their movements. They are able to translate what they are learning with Cortney at CrossFit Loop to be more competitive on their sports teams. Cortney ensures that each child is coached to their individual needs ensuring that they are working efficiently and safely. My 9-year old is pushed just as hard as my 13-year old and they are all reminded that integrity is more important than being “first.” If you can get passed her being an FSU fan (alum) Cortney is great.
Fantastic experience: I just recently started coaching at CrossFit Loop. I am blown away by the quality of coaches, I am thrilled to be a part of the team. The sense of community is unparalleled; I have never had such a warm welcome! I love seeing new athletes come in and instantly be welcomed by everyone here- even the games level athletes. It is am amazing box and I think the best CrossFit gym in Castle Rock Colorado! I highlight recommend anyone interested in CrossFit drop in to check CrossFit Loop out for yourselves.
Fantastic experience: When I moved to Colorado from Pennsylvania I left a Box I loved.. I really never thought I'd find a box where I was as challenged to push myself beyond with people I loved to workout with.. Crossfit Loop is my old box and than some! Coaches not only made me feel welcome , most of them I now call friends! The loop is the real deal and you feel the connection and positive vibe every time you walk thru the front door!
Fantastic experience: I have been a part of Crossfit Loop since the beginning. The atmosphere is contagious, and it makes you want to come back. Its easy to tell when people take a true interest in you regardless of ability or experience, and that is exactly what you get at Loop. Pop in one time and you will hear your name the whole class, not just from coaches but athletes as well. Like I said it not hard to tell when people just care:)
Fantastic experience: Where do I begin when giving a review for a place that is more than just your typical Crossfit gym. It's the only place I've ever been where you are welcomed with a hug/fist bump/high five/butt slap/or your simple hello every day you walk through the Loop doors. The coaches are killer, their knowledge and work ethic is amazing. They know when to push you harder or back off and scale your workout. All the coaches bring something new to the table, Olympic lifting, Regional qualifier, Mental/Physical health and knowledge bombs. With such a wide variety of people/coaches we have a sick music selection ranging from Wide Spread Panic, JaRule, Gangster Rap, Garth Brooks and maybe some Bob Marley. Dog friendly/kid friendly, not much else you can ask for.
Fantastic experience: My husband and I moved down to Castle Rock a little over 2 years ago and we had a to find a new box. We settled for the first one we found but after a awhile we noticed we were not making any gains and we were on a mission for a new box. Some close friends told us about CrossFit Loop so we took the family to check them out. Our first steps into the box, we instantly knew we found our new crossfit home. The owner, Korby, was very energetic and made my husband and I (and our 3 kids) feel very comfortable. The coaching staff is one of the best I have ever worked with. Within 4 months at CFL, my husband and we making new PR's every week. We are very happy with our progress and glad to call CFL our home. Our kids ask everyday if they can go to the green gym!
Fantastic experience: I'm in love with this box! Crossfit Loop has the best coaches and the best members...I just love how much support and knowledge is at our fingertips from the coaches and seasoned members. Now working out is actually hanging out with a bunch of friends while getting movements and workouts perfected...If you haven't tried it you should make time to join us :)
Fantastic experience: After visiting five BOXES, I have finally found the perfect one for me and my family. Loop succeeds because it maintains the delicate balance of challenge, expertise and congeniality. The trainers are well versed in Crossfit technique but know how to cater to the individual. They pay close attention to your ability and will challenge you without being presumptuous. They have the brilliant ability to make you feel like you are apart of their family from the moment you step into the gym. My children and I look forward to attending classes and we always leave with a smile on our faces for having experienced Crossfit Loop. If I could give this gym 10 stars, I would!
Fantastic experience: I wanted to wait a few months before giving a review. I never give reviews unless I have a deplorable experience or an exceptional one; this is the latter. This review is a bit long, but read through it; especially if you are considering starting Crossfit. I originally started Crossfit at a nearby popular gym. I was 54 years old, grossly out of shape, and very overweight. It was originally scary, but I showed up one day and persevered. The trainer I had was patient with me, scaled back the workouts, and knew when to push me, and when to hold me back when I was a little overzealous(To stave off injury). The gym itself was a little "cliquish" and I got the usual smirks and double takes only a large person would know, when entering a gym. However, the trainer was that good, and worth me sticking to it 3x/week. Unannounced to me, the trainer inexplicably disappeared. The next trainers were friendly, but no where near as knowledgeable. It was then I realized how important your trainer is in Crossfit; no matter what level you're at. The "Cliquish" feel was still there too, so I decided to follow the trainer. Through the grapevine, I had heard he had switched to a new gym ("Box" in Crossfit language) that was opening up in Castle Rock; Croosfit Loop. I had to wait a month or so before I could go and run out my contract with the old box. Upon entering Crossfit Loop for the first time, the difference was immediately noticeable. First of all one of the owners, a husband and wife team(Korby & Anne), usually greet you at the door. You also notice the friendly, family like atmosphere. Although most of my kids are out of the house, there's a daycare for your young kids while you work out; and they even have some family workouts. That barely-accepted-cliquish feeling I got at the old place, is nonexistent at Crossfit Loop. Everyone says hello and introduces themselves if they have never met you; management and members. This is perpetuated by Korby and Anne, and is consistent through out the box. The members range from beginners like my self(Although I believe I am the biggest) to high level Crossfitters ready for competition, all mixed in the same class. This too gives you something to work for; although not once have I ever felt any of them looked down at me. In fact, If I'm lagging, or anyone is lagging, they all spur you on to finish. However, the most important feature of Crossfit Loop, and any Crossfit you start, are the trainers. The trainers at Crossfit Loop are top notch. I make it point to not only attend the class of the trainer I followed here(JT) but also use the other trainers they have here too. Each one I notice has a different specialty. Each one is highly trained and you can tell the difference; Korby and Anne took the time to hire the best. They have an onsite nutritionist that has also been very helpful, among other programs. I have a long way to go in my journey, but my the nonexistent core I had when I started, now exists. I still have 60-80lbs to lose, but it takes time, patience, eating the right foods, and Crossfit Loop. I hope this was helpful, especially to all the people considering Crossfit for the first time and wondering if they can do it; If I can, anyone can. The hardest thing is taking that step through the door. Do that, and the people at Crossfit Loop will handle the rest.
Fantastic experience: I love the Loop! It's amazing the progress I've made since becoming a member last October. This is due to the patient, professional and dedicated coaches. This success was also due to the highly supportive Loop athletes. The Loop is a family affair for us; my wife, two of our kids (2 and 4) and I are all Loopers. If you are traveling through Castle Rock, you should check it out while in our great community. If you live in Castle Rock or the surrounding area, look no further for the best box in Castle Rock! I look forward to meeting you!
