X3 Sports - North Marietta

The staff are friendly, supportive, and welcoming. The facility is clean and well maintained. The classes are fun and engaging. I really enjoy the BJJ classes with Jackson. You can tell the instructors are knowledgeable and professional. Overall this company really seems to take care of their employees and provide a quality experience.

Training at this gym has been one of the best decisions I’ve ever made. I’ve been training in both Muay Thai and Brazilian Jiu-Jitsu here, and not only have I grown stronger physically, but I’ve also built real confidence in my self-defense skills. The coaches are top-tier — knowledgeable, supportive, and genuinely invested in helping you grow no matter your experience level. What really sets this place apart though is the community. From day one, I felt welcomed. Everyone looks out for each other, pushes each other, and celebrates progress together. It’s not just a gym, it’s a family. And the UFC watch parties? Unreal. Fight nights here are an event! The energy is electric, and it’s such a great way for everyone to bond outside of training. It brings the whole team together, and honestly, it’s become something I look forward to just as much as training. If you’re thinking about starting Muay Thai, BJJ, or just looking for a great gym with an amazing atmosphere — this is the spot. Highly recommend.

This was my second Visit to the North Marietta location. My wife and I attended an recent watch party event and promotional class lead by one of their veteran boxing coaches. We came back today to attend her first complimentary boxing class. I took fast track class before hand and then boxing. It was intense. I loved it. My wife enjoyed herself and had a great workout.

X3 sports is a great place to go. My seven-year-old son, 14-year-old daughter and I all do boxing many times when we are done with class, my son and I will get in the boxing ring and spar for a bit. He is only seven years old and they are doing a great job teaching him. at least one out of three times that we are here, the three of us also lift weights for 12:30 hour. They are very family oriented and have almost every type of work out you can think of. If you stop at X3 sports, make sure you ask for Billy. I think his last initial is G.

A fun and motivating place to get real results! I love X3 and highly recommend it for anyone wanting to find a smaller gym where you can be challenged and motivated. I’ve been coming here for years now and it’s like my second family. The trainers are great and the have a number of different types of classes available. Be prepared to sweat and have a great time while doing it!
