Found this CF box on my way back to the hotel one day. Looked them up, contacted them via their site and got a response within a couple of hours. Set up a drop in session and got in with the 7 pm crew - a fun bunch. the manager/coach was super helpful and managed the class very well. Overall a good spot to get your WOD on if youre in the neighborhood. Ill be coming back to this spot again when Im back in town - fo sho!

Wouldnt work out anywhere else. Great atmosphere and knowledgeable, friendly coaches. If it works for someone who sits the majority of the day, it can work for you. Suitable for people of all skill levels.Highly recommend!

Very hospitable. We were greeted with a friendly warm smile and made to feel very welcome. Coach, owner and members were inclusive and made us feel at home. Varying degree of athletes yet no judging. We definitely plan to continue to work out there!:)

Dropped in two days ago with my wife. Easy communication with owner, no problem getting registered. Big facility, well equipped in central location in downtown Greenville. Good coaching. Will definitely go back whenever Im in G-ville.

My favorite box to drop in at when I am in town visiting family! My first time there everyone was extremely welcoming, and its one of the few boxes Ive dropped in at that has let me drop into open gym and continue doing my own competition programming! Very fri ndly atmosphere, great facility, and the athletes and coaches that were there during open gym were great and even remembered me when I came back ;) 10/10 recommend this place, especially if youre looking for a great place to drop in while youre in town!!

Been here 6 months and I love it!

If your looking for a great place to drop in, Crossfit Reaction is the perfect spot in Greenville. I was in town for a week and needed a good sweat. Yes, the facility is nice.....yes, its convenient.....but the people & the trainers made me feel very welcome. I will definitely be hitting them up again next time Im in town!!

If you are looking for a crossfit box this is the place! My husband and I travel often for his job and this is where we workout while in Greenville. The coaches are by far the best, one of a kind and care deeply about their clients (bar technique included.) The community is friendly, motivating, accepting, and very encouraging; our home box away from home!!

I was traveling for the holidays and needed a CrossFit gym to drop in that would have reliable, competitive programming and provide space for some skill & accessory work. CrossFit Reaction delivered! I wanted to squeeze in a second visit while I was in town. Amy is a great coach, and Brandon is super welcoming. The regulars at Reaction were inviting and fun to train with. I recommend CrossFit Reaction to newcomers and experienced CrossFitters who are looking for a welcoming community :)

Love our CrossFit Family!!! ❤️❤️

Was in town from Houston Texas and did a drop in. Awesome spot. Met coaches Amy and Daniel. Both are great. Amy ran the workout and I got a lot out of it. Thanks guys!John YHouston Texas

Dropped in here. I travel for work and have been to boxes across the US. Reaction is solid. Plenty of space and equipment, good coaching, friendly people. Definitely worth checking out if you’re looking for a box. I’ll be back next time I’m in town.

This box is amazing, they make you feel at home. Even if you are new, they make sure they stay with you until you get proper form ( without charging unlike other boxes), they do it because they really care about you and your fitness goals. The facilities are impressive and the coaches are seasoned and all have a great heart. This is by far the best box ever.

This was my first experience at a CrossFit box and I was blown away. The three coaches I met - Brandon, Amy, and Daniel - were extremely welcoming and informative. The facilities are top notch and the community seems to be very tight knit. Will be returning ASAP!

I dropped in for the 8:30am class with Amy, and it was awesome! My husband and I really enjoyed the class and the space is great. Definitely recommend for those looking to drop in :)

Brandon was the coach of our 4:30 CrossFit class. He was SO knowledgeable and fun! Even asked if anyone had any specific mobility they wanted to work on in the warm up. Definitely will be back!

Dropped in yesterday and the facility is great. The people - coaches and athletes - are welcoming and friendly. The workout was high intensity, but of course modifiable. I really enjoyed class and will visit again when I’m in town!

Definitely recommend this gym for those who are traveling and need a place to workout! The coaches were relaxed and welcoming. The community at the gym also reflects the coaches that work there. Everyone was welcoming and willing to make the drop-ins feel part of the community!

This is a great box! They are so friendly and accommodating. We’ve dropped in a few times while visiting family and they always remember us. The WODs are always challenging and fun.

Completed a drop in from out of town and couldn’t be more pleased with the experience. The coaches were accommodating, approachable and motivating. The members were friendly and inviting. The facility boasts plenty of floor space and ample equipment for training. Overall, a phenomenal box!

Absolutely love Reaction, the programming is great, the atmosphere is welcoming and exciting, and the community is amazing. Everyone treats you like a best friend and are so supportive. I have been going for about a year now and have seen improvements in all aspects of my health and strength. Definitely suggest Reaction to anyone dropping in for a good workout/ looking for a new box to join!

Had a great time at CrossFit Reaction. I did a drop in while traveling from Chicago. Everyone was welcoming and I had a great workout. Great to visit if you are in the area and need a workout!

Dropped in from Chicago and the class was great! Great coaching, programing, and everyone was very friendly. Would definitely recommend and will come back when Im back in Greenville!

I dropped in while in Greenville for work. They were so welcoming toward me! I got in a great workout and met some really great people. I would definitely recommend this CrossFit box. They are a great community of people!

Absolutely love this gym! I have dropped in several times on weekends and every time feel very welcomed by Brandon and Amy. The community is incredible and the workouts are well put together. I would highly recommend this gym to anyone living in Greenville, SC or stopping through.

Had a great time dropping in here! The coaches were all very friendly and the gym is clean and organized! Recommend for sure.

After moving downtown Greenville, I started working out at Reaction, after having been at another gym for 5 years. They were very welcoming to me when I first joined, and I have made great friendships. The community is just as important as the workouts. The coaching staff is very well educated, always willing to help, and push me to be better everyday. Efficient and safe movement, positive competition, and self improvement in and outside of the gym are daily reminders from the coaching staff. Best gym in the upstate!!!

What an awesome location!! Very rare that I would post any review online but the owners spent a fair amount of time making sure that I felt welcomed and had a great workout. I would recommend this box to anyone visiting or who lives in Greenville, SC!

My husband and I were in town for the week and dropped in to CF Reaction. Everyone was so welcoming and the programming was awesome! Got a great workout every day. Thank you so much for a fabulous week of fitness!

Traveling for work, found this great box in Greenville. fantastic location right down town. Tons of space. ample equipment. coaches are knowledgeable and helpful without being overbearing. You will not be disappointed with your time here. whether your just dropping in or looking for a new community

The gym is very nice and open with tons of equipment and what is even better are the coaches and the members. Everyone made me feel incredibly welcome and like I was part of the crew from the moment I walked in. CrossFit Reaction will be my go to CrossFit gym when traveling to Greenville!

Super friendly coaches and owners! Was visiting and still felt super welcomed. Was coached throughout the session. Great location as well downtown!

In town for business this week,Dropped in today on a short notice,Brandon welcomed me and my friend with a warm housepetality, explanations, and we gladly entered the class with coach Amy who was absolutely great, professional, and super nice.Would definatly come back again, will recommend to others and on the next arrivals in town Ill check in.Great vibes, cool people, fun!Highly Recommended

I have been a member of CrossFit Reaction for just a little over a year now. This is most definitely one of the best decisions I have made for my physical and mental well being. I am someone that gets bored very easy or finds any excuse not to do something, especially if takes me out of my comfort zone. Brandon and Amy are amazing trainers, truly care about their members and want to see you succeed. CrossFit and CrossFit Reaction brings a lot more than just a workout. DO IT!

The best most encouraging coaches I’ve ever had! They push and encourage you every step of your journey. The people are loving, supportive, and treat you like family. You will always leave feeling so much better then you did entering! I have met the most influential people in my life at this gym!

They have very educated coaches, great programming, and a fun community. This is one of the most diverse communities you will see in the Upstate and some of the most welcoming people. You will see all skill levels of fitness here and there is something for everyone. Plenty of open gym times and additional programming available for athletes trying to progress to that next level. If youre in the Greenville area - this is the box to check out!

Was looking for a new gym after moving back to the area. Dropped in here a few times with Amy and Brandon. Unfortunately, I couldnt make their schedule work with my work schedule for a long term plan, but I LOVE them, their programming, and their community. Amy is awesome. Stop in. You wont regret it.

This is an amazing gym with fantastic coaches! I have always enjoyed the community and atmosphere here. The coaches go beyond what you expect to make sure that you are taken care of, and Brandon and Amy are some of the best people youll meet! I highly recommend this gym!

This gym was amazing! I came from ATL for work and dropped in twice. The coaches were very welcoming, in fact, the entire gym was. Most definitely will be back if I’m ever in town again. Thanks!

I come to CrossFit Reaction every time that I make a trip to Greenville. The first time that I came, I was warmly welcomed by the CFReaction team. There’s never been a time where I was not disappointed or mistreated. They really do take care of their guests and their athletes. All the coaches are so knowledgeable and accommodating. I love it here. I can’t wait to come back to say hi and workout with them the next time I’m in town.

Great facility, well equipped and clean. Convenient downtown location with an inviting and friendly staff. Thanks for a great WOD!

I dropped into Crossfit Reaction while traveling for work a couple weeks ago and really got a lot out of it. Brandon, Amy and the crew were totally welcoming and the workouts were challenging and of course fun. I enjoyed being there a ton, even for a couple days. Great facility. Ill definitely be back next time Im in town.

Dropped in today while in Greenville on Business. Coach and WOD were great and the facilities are clean and top notch. CF Reaction is a very welcoming gym that Id highly recommend checking out.

I’m for vacations in Greenville so I came to CrossFit Reaction to take a couple classes and this first day was very good. I really enjoyed my time there, athletes were nice and the workout intense as I like it.. Def worth it!! Going back tomorrow.. See you guys ;)

THE PEOPLE’S COACH, BRANDON CHAPINI was stuck in Greenville for a couple of days for work and they made me feel at home while I was at CrossFit Reaction. Classes are super fun, but also informative and adaptable for all ability levels.Thanks Brandon and his team for having me, y’all are awesome!

I have been working out at CrossFit Reaction for 3+ years and I still enjoy coming in each day and giving it my all. The community at this gym is unlike any other I have ever been a part of. The coaches are dedicated to teaching their members each movement the correct way as well as making sure no one gets hurt. I look forward to my workout each day-- I cant imagine my life without CrossFit Reaction. Its unlike any other CrossFit gym around!

CrossFit Reaction is an incredible place! The trainers are super knowledgeable and take the time for individual attention. The culture at Reaction is amazing- people are constantly having fun while kicking ass and working hard. CrossFit Reaction is unique in multiple ways and if you want the best, check it out!

I dropped in to CrossFit Reaction as I’m staying in Greenville due to evacuating for Hurricane Florence and I’m so glad I did. Everyone is super friendly and welcoming. The owner, Brandon, and Coach Charles made me feel right at home. I got in a great workout and enjoyed myself in the process. This will be my go to box whenever I’m in the area. Thanks!

I love CFR, Ive been a member of several CrossFit gyms and this is the one where I truly feel at home. Amy and Brandon are super knowledgeable and want to help you reach your own personal goals. The whole community is amazing!

Great place to drop in if on the road. Would definitely go back.

Dropped in while I was visiting from out of town. Everyone was very friendly. Coaches were helpful and very inviting. Definitely would recommend to anyone traveling to Greenville and needing a place to drop in at.

Randomly dropped in while visiting for the SEACSM conference and felt very welcomed! Everyone was very friendly and the programming was great! Highly recommend

When I moved to Greenville in 2016 my first order of business was finding a gym home. I dropped in at several gyms in the area and while I liked them all, none stood out. Reaction was my last stop and as soon as I walked in I knew this gym was the one. I received a heartfelt warm welcome by not only the coaches but by all of the members. I gained an immediate tight-knit friend group and my performance as an athlete went through the roof. The coaches are so knowledgeable and care about your progress and goals. The programming is challenging but scalable for any level of fitness. Reaction has become my happy place and what I consider my second home.

My husband and I dropped in for two classes while in Greenville. We were greeted warmly by coach Amy and owner Brandon. Members who were working out were also very welcoming and interested in learning about us. We were well coached and totally enjoyed both classes. Definitely check out this box while in Greenville. Cheers.

The coaches and people here are very friendly. Amazing group of people to workout with. Would definitely come again

Great facility with a friendly and helpful staff. Definitely plan on dropping back in.

Had a great time! Excellent coaches and amazing environment!

Great box to drop in! Nice people who make you feel welcome. Well equipped and very clean. Glad we found this place.

CrossFit Reaction is a great place to start your fitness journey. I had been doing CrossFit for awhile when I found reaction and I have grown so much just attending. There is a great atmosphere and everyone cheers everyone on. Also they made the workout easier so i could complete it as well.

Awesome gym, tons of space and great equipment. Easy to find in the city and the coaches are extremely hospitable. Crossfit Reaction is easily a 5 star rating!

Extremely welcoming environment! The coaches here take the time to address each person in the class individually, and give helpful notes throughout the workout. I dropped in today, and felt like I was a part of their community!

We dropped in while visiting family in downtown Greenville. Extremely welcoming environment. The facility is incredibly clean with excellent equipment. We will be back!

Everyone is very friendly and welcoming. We had a great WOD!

As a drop in it was a welcoming and encouraging environment. The athletes and coaches were great and I am definitely coming back again when I visit Greenville, SC!

If you are looking for a place to get fit and strong, challenge your self, grow mentally and become part of an amazing community, then look no further then CrossFit Reaction! I cant think of enough amazing things to say about this place. I considered myself a very active and fit person before coming here, and since then I have become a stronger all around athlete. In addition I have made amazing friends. By far the best Crossfit gym around!

Unreal. experience. Coaches not only took time to make sure you are welcome but go through every movement to ensure safety. Great programming included as well

Dropped in from Charlotte for a workout and had a great time. Great workout and coaching!

Love this place! Knowledgeable coaches, amazing community, encouraging yet challenging atmosphere. Youre missing out if you havent been here

Doesnt look like much from the outside, but I get some of best workouts done here. It has all the tools to help you reach any of your fitness goals. And no matter your fitness level and experience the trainers will help you through the whole process. Everyone that works out here is extremely nice, social and encouraging. Once you try it, youll be hooked. The Sport of Fitness is HERE!!

Great experience. Highly recommend for a drop in!

Great coaching staff! Dropped in for a few days and loved it. Everyone is super welcoming.

Best box in the Upstate. Fantastic folks, great coaches and excellent facilities. Location ideal for drop-ins!

I love crossfit!! Not only do you get a great workout, but the trainers are awesome and the camaraderie within the gym is fantastic! If you are serious about getting in shape you need to check them out. They do one free intro lessons on Saturday mornings. Just need to email them via their website.

Awesome concert venue. It may seem like a locals spot, but it hosts international talent such as Taylor Swift and Pitbull.

Reaction is the BUSINESS!I’m brand new in town, and was just getting settled in enough to check out a CrossFit gym.The moment I stepped in I knew they had a GREAT CULTURE. I was there for the 4:30 class and it was a top notch workout ... (for a out of shape guy like me) but the music/workout/energy/people were rememberable.I spoke with Brandon on the phone and found out he was one of the owners. He & Amy really know how to create a CrossFit gym. Everybody was real friendly and I can’t wait to go back day after day.My only thing is if YOU go once just for a workout YOU will probably never leave! So beware!Also shoutout to BRANDON’S WIFE for throwing some highlights on Instagram! Motivation all day!

Excellent Sunday workout! I was in Greenville and needed to drop in and Chris was great and everyone was extremely friendly and made me feel like a regular. I highly recommend dropping in Crossfit Reaction to check it out. A great way to end the weekend. Thanks!

Crossfit Reaction is the best! The coaches and members truly want you to succeed. It is a great facility with a ton of equipment and smiling faces!

This is definitely the place to come in Greenville. Everyone is friendly, inviting and the staff knows what they are doing. It can be challenging to find a Crossfit gym with that IT factor and this one has it. I felt like I was actually coached (even with 20+ people in a Saturday class) and I left feeling like I couldnt wait to come back. Thanks for everything!

Started crossfit about 2 years ago and I wouldnt go anywhere else. Reaction is by FAR the best programming, coaching, and community. They will get any skill level engaged.

When you are in Greenville, definitely make it a priority to drop-in at CrossFit Reaction! Not only are the coaches extremely knowledgeable and give great queues, but they are encouraging and friendly. The facility is well-equipped and incredibly clean with excellent equipment. This community goes above and beyond to welcome all people- visitors, seasoned newbies, veterans, regionals athletes, first-timers, and everyone in between. I love dropping in, & as a CrossFit Coach, it makes my heart happy to do be a resident drop-in every single time I can! Thank you, CrossFit Reaction!

Great Gym with a friendly staff! Super fit group who were all very kind and welcoming!

Crossfit Reaction has an friendly atmosphere with quality equipment. I joined after moving to Greenville from NC and met some great friends at this gym while having fun working out!

I enjoy dropping in when Im in Greenville. The coaches are approachable and knowledgeable.

Awesome gym with a phenomenal environment. Coaches are knowledgeable and motivating. 10/10 would recommend.

I love Crossfit Reaction. So friendly and understanding. Ive lost 15 pounds in less than 3 months. Weight loss is not my goal but I have a pretty good fuel tank. When I was 45 I played softball and I was sore the next day, that was my first sign. Anyway 7 years later I cant shake it but Crossfit Reaction is doing the trick🙂

Seriously, this is the BEST workout I have ever had! I cannot say more about Brandon, the owner, and Crossfit Reaction than, WOW!. Crossfit Reaction incorporates everything you need in a workout: stretching, weight lifting and aerobic, all balanced perfectly for the hour during which you work out.Every workout is completely different and Brandon has all the equipment needed. He is so motivating and all his other clients could not be more supportive. Any fitness level is accepted!It is so much fun, and very empowering to do Olympic weight lifting.I love it!

I dropped in to Crossfit Reaction from out of town and was really happy with the warm welcome, clean and well-equipped facility, and ease with which I was able to get my workout in. I look forward to stopping in next time I’m in town.

Great team!!! They are always there to help motivate you. The coaches really take the time to listen and make sure to modify the workout if you need it for any specific day. They also make sure to check in on you if you miss a day to just make sure you are ok.

Top notch trainers with a side of a great community of members. This gym and it’s members changed my life and will certainly help you be the best version of yourself. I’ve visited other local crossfit gyms here and across the country. There is definitely something special at Crossfit Reaction. My favorite part is the positivity circle that coach Amy Fryt starts after class sometimes. Great place to get a killer workout and also meet some new friends!!!

Great gym. I like their style of working on strength first, then the WOD (after warmup of course). I was visiting out of town, they allowed me a class after purchasing a shirt, cool people!

Ive been at Crossfit Reaction for about 9 months now. I came from another gym because I wanted a more complete Crossfit experience. What Ive found is a great group of people with programming that works for me and, from what I can see, every other athlete on the spectrum. The coaches are engaged and push me without trying to kill me. The facilities are well maintained and clean with every tool that you could need.Overall, a fantastic place to challenge yourself with an encouraging and supportive environment.

If you are new to Greenville or traveling through the city, you must check out CrossFit Reaction! The owner, Brandon, and trainers are absolute experts at designing challenging and constantly varied workouts. The community is incredibly diverse, welcoming and competitive. And the location in downtown Greenville cant be beat! Ive been a member for ~1 year and have seen constant improvements in my performance, plus Ive met some of my closest friends in the city! No other gym compares to CrossFit Reaction it youre are looking to be pushed past your limits while surrounded by amazing people and athletes!

Awesome workout with CrossFit Reaction - and a great facility close to town and close to good places for food and a beef after workout!

Awesome Box! In Greenville for work dropping in for two days. Great community. Awesome WOD’s. Clean. Great Equiptment. Couldn’t ask for more!!!

This is my favorite box to drop in to! The 6am class is extremely inviting and very friendly. I always look forward to my trips to Greenville so I can get some real work done.

Started a little over a 2 months ago,with no clue how to do crossfit. The beginner boot camp was perfect and the coachs have been great in teaching me the proper form and routines to get me started. Would highly recommend crossfit reaction to anyone.

Great Box. Everyone introduced themselves making me feel like I was back home at my local box.

Great atmosphere and very welcoming staff! I’ll be back for sure

Best Chili and Hot Wings in the city!

This is a great gym owned by great people. Warm and friendly to visitors and extremely helpful in training.
