I love the boxing classes. Being out of shape, I was unable to complete some of the more challenging classes such as fast track.
I like the variety of workout from the different instructors!
Love this GYM
Very focused and friendly trainers. Definitely recommended.
I have been a member of X3 Sports Marietta for over four years. I enjoy the kickboxing classes because they focus on a high level of personal fitness as well as martial arts and self-defense skills. The instructors are extremely knowledgeable and very experienced. They deliver very challenging classes and are able to provide individualized instruction within a class setting so that everyone can participate at their own level. Every class is different with a wide range of fitness activities as well as punching and kicking combinations. The instructors are extremely friendly, very personable, and always make you feel welcome and part of the class.
I recently visited a quite expensive upscale club because I was interested in their tennis program. I was also able to try out two of their boxing classes but I was really disappointed. The classes felt like your typical hyped-up fitness fad that comes and goes. I was new there, first time, and the instructors did not know nor did they seem to care. The room was dark and dingy and the bags were hung up way to close to each other. The schedule was very tight according to a preset computer program on fancy screens. The instructor did not come around and check on people (no room anyway), there was no individual feedback, there was little demo and pretty much zero interaction between class and instructor.
I have not been back and I'll find my tennis somewhere else. There is absolutely no way, I am going to give up my kickboxing at X3 Sports Marietta. This is the real thing! Special thanks to DeAngelo and Terrance but all of you guys are awesome!
The community, the challenge and the results.
Very Friendly and helpful associates. They make the workout fun and exciting for my Son.
X3 offers the best training classes in town. The trainers are professional and dedicated to their profession. The trainers advice and guidance help to reach your personal goals.
Great staff and awesome classes.
It's a great environment with knowledgeable, caring, and motivating instructors.
The instructors are great and take time to help you use proper form and get the drills right
Trainers are amazing and staff is extremely friendly. Wish the family prices were cheaper though!
Perfect combination of everything you need/want at a gym.
The trainers and how the same classes are available multiple times throughout the day.
Vagner is an outstanding trainer and very patient with beginners such as myself. The experience has been everything I’ve expected and more. Having a great instructor such as Vagner has made the process much more welcoming and has me very excited about the journey ahead. Everyone that I have interacted with on the staff has been super friendly and welcomes with open arms. I will definitely recommend this facility if you want to take on martial arts!
Friendly staff. Trevor class is fun
I just enjoy going there. I feel more confident in myself.

The different classes and the unlimited class memberships
