The trainers are great and take the time to slow things down for me. The facility also is very clean.
The variety of classes and the hands on instruction from trainers
Everyone is very knowledgeable and will help you to succeed if you are willing to put in the work. I have enjoyed coming here and will continue to come. The professionalism is great and it’s an open and accepting environment to improve on your body and health goals!
X3 is the quintessential fight gym. You walk in and you are immediately greeted by staff athletes who treat you like family. Everyone there makes everyone better. sometimes I often think did the term iron sharpens iron come from this place?
The instructors are phenomenal and professional, the atmosphere is world-class, and there is no other place I would want to train.
X3 Marietta is one giant family. I have only taken a few classes and I feel like I joined up with one huge family that is all supporting and driving everyone else's goals. Everyone is extremely supportive and encouraging, not a shred of negativity to be found in any of the classes or with any of the members, staff or coaches. X3 is an outstanding place to train.

Great first experience

Fun, intense workout that caters to beginners!
I am pretty out of shape, but everyone there is very supportive and encouraging without being patronizing. This includes all the instructors I have trained with and the other members as well. Instructors are always curious as to what it is you want to work on in a given class and seem to have a good feel for what they can legitimately expect from you and tailor their instruction accordingly. As I become more comfortable with the basics, instructors are able to accurately gauge my progress and show me more advanced techniques.
The trainers are great! Very knowledgeable and encouraging.

X3 is super! Thanks to the instructors I feel amazing and I look fabulous!
Thank you so much for helping me to get my confidence back!
