This is a CrossFit Mecca on the Cuyahoga river in the Flats neighborhood of downtown Cleveland. Huge space with some very kind and welcoming Clevelanders. Equipment is brand new, space is immaculate. Took a combat class with coach Zac, basically cardio with some weights, and loved it. Zac gave me a tip for Goblet squats that improved my range of motion and eased a sore back immediately. Very positive environment and you can tell the owners/coaches care about the athletes. Facility offers an open gym for much of the day as well as scheduled classes. Well worth the trip if you’re in The Land and need to sweat.

C4 is a gem! Family circumstances found me in Cleveland for the summer, and being a 5-year CrossFit veteran, I've been to a fair number of gyms for drop-in. C4's owner, coaches, and members welcomed me with open arms. The programming and coaching is top-notch. The gym and equipment itself is sparkling new and kept immaculately clean. Not to mention the gym community support is amazing. Members clearly care about their fellow crossfitters and I quickly became part of their friend group. Coaches care about your wellbeing in and outside the gym There is an in-house PT as well as nutrition consultant. The owner is very quick with all communication and extremely willing to work with individual schedule changes. I cannot say enough positive things about C4. This gym is truly a fitness destination! I'm looking forward to my next drop-in when I'm next in Cleveland. Thank you!

This place is one of the best gyms you could be apart of. The coaches are extremely knowledgeable and helpful. They offer so much more than just CrossFit classes. Their equipment is top of the line and their programming is fantastic.

Looking for a fantastic CrossFit experience close to downtown? C4 is the place to go. Their huge facility is clean, modern with loaded with the latest equipment. Recently celebrating their one year anniversary this gym on the rise. Great community with enthusiastic members, talented staff and a great location makes this box a place you should check out whether you are a CLE resident or dropping in from out of town.

Absolutely great gym! Amazing facility. Coaches are top notch and great people. Additionally have some amazing athletes that workout here, real nice community! Programming is also well formed and tough.

Can’t say enough great things about this gym! Not only does it have new state of the art equipment, and a beautiful view of downtown Cleveland, the community is so fun and welcoming! I have been to several gyms in the Cleveland area and this is, hands down, the best gym I have been to. If you’re in the market for a new gym, this is definitely worth a try!

The best gym in Northeast Ohio … hands down. State of the art facility with extremely nice equipment and very welcoming to new members and drop-ins! I highly recommend you check it out. Almost too good to be true.

The three things that stand out about this gym are the coaches, the community, and the facility. The gym itself is a state of the art facility with plenty of natural air and the best equipment. Coaches are top notch, and give the utmost attention whether you are a first day beginner or a seasoned veteran. The community is completely unmatched. time together and celebrating achievements goes far beyond the metcons and we gather around each other regularly. C4 is a place where your friends quickly become family.

This is the best CrossFit gym in Cleveland! I’ve been training here consistently for a couple years and I love the new equipment, the knowledgeable coaches, the community, and the amazing view!

A year and a half in this amazing CrossFit and I cannot recommend it enough. Great and Knowledgeable coaches, intricate programming to fulfil your fitness goals and supportive community.

Best CrossFit facility in Cleveland, hands down. I visited a few of them after moving here before settling on C4. Excellent equipment and good, varied programming that easily scalable. Good members, too. It just started a year ago and they're still refining the gym and the experience. If you just visiting or looking for a new gym give it a shot.

Best gym in the land! The coaching and overall atmosphere is what will set this gym apart from the others. From veterans, to beginners it’s the best CrossFit gym to be with!

Best gym around! The equipment is top of the line and there are multiple pieces of equipment which allow for fluid, full capacity classes to be held. The coaching staff is incredibly knowledgeable not only in functional fitness but also within their own fields of expertise (e.i.: physical therapy and nutrition coaches). The facility also offers services for recovery which is convenient for members allowing them to get all needs met under one roof! There are Top of the line locker rooms with multiple showers that are cleaned daily, and full size mirrors for that post-workout selfie! Beyond that, the members are what really make the gym what it is- competitive, fun-loving, encouraging group of like-minded athletes who come in daily to reach their fitness goals! Make sure you don’t miss a Saturday 8am combat class followed by the Cle Script sign selfie with the beautiful skyline in the background!

This is a top-tier CrossFit gym. It has great coaching, premium equipment, good culture/community and management is customer-centric. If you’re a veteran crossfitter or looking to start your journey, C4 is a great option.

Such an amazing facility and gym. The coaches and programming are what sets C4 apart particularly. In addition, the offer a wide range of classes for all levels. Definitely suggest you check them out!

C4 really has helped me transform my athletic ability. Friendly/inviting gym. Love the structures of the class. HUGE facility with option to use the "open gym" during business hours if you can't make class. Helpful/supportive coaches. Really really great programming.

I came to this gym months ago with zero crossfit experience and barely a workout routine. Now I'm there 6x a week attending supportive, yet challenging classes that produce serious results. Awesome community of people, great facility, experienced coaches.

I always love dropping into C4 when I am in town. The community is so welcoming. The coaches are encouraging and helpful. The programming is the best I have ever experienced dropping in matched with a state-of-the-art facility. After class you can cool down in the sauna and shower. Just make sure to bring a towel.

I’ve been to a lot of CrossFit gyms, and many in the Cleveland area, and none come close to the quality C4 provides. The gym itself has a ton of space and every piece of equipment that you could need or want. What really takes C4 over the edge are the coaches and the programming though. The programming pushes you in a way that gets results, and the coaches give queues that click with the athletes on the floor. If you’re trying to take your fitness to a new level then C4 is the gym to do it in.

This place is my second home. Best in class programming paired with top-notch coaching. Elite training facility. Incredible Sauna. Fantastic group of athletes of all levels. Best gym in the USA.
