The gym's sense of community is truly uplifting. The trainers are friendly and encouraging, fostering a positive atmosphere where everyone feels included and supported.
I’m happy with the experience that I get from X3 you get to meet new people, make new friends, and get trained by professional fighters and coaches. I love X3 cause I get to practice Muay Thai and when I was younger I would watch the sport so begin apart of it and having the chance to do it is even better, also my goal is to compete soon.

I like the location but also how everything is in one place where I can take a multitude of classes when it pertains to martial arts and also still get that gym experience with the weights and treadmill.
I think the coaches are cool and I appreciate the fact that they switch up the class styles often. You also can go to different class times, and each coach will do things differently, so variability is always offered. I like the fact they're always playing the right type of music for the sport. It's a cool place to go to for a nice release.
I enjoy coming to workout here. I always feel comfortable and welcome here and I've never felt intimidated or anything like that. The coaches I've worked with have all been really good at working with beginners and explained things well.
Challenging & fun
Amazing facility and staff and a extremely motivational environment.
Have been amazing so far.
I’m really happy with my choice to come back to X3 at the north Marietta location. Everyone is super friendly, and the coaches also go really hard during classes and push you to be better. There is a lot of attention to technique in whatever you’re doing.

X3 is such a great environment with so many fun & different ways to work out, get stronger & feel better!
The staff was friendly and made me feel like family from the first second I walked through the door. Every was knowledgeable about their jobs and patient with breaking it down for everyone from the advanced students to the beginners. Great music, new equipment, and a wide range of classes. By far the best gym I've been in and I can't wait to join when I move back
X3 is top notch. Everything from the equipment to the trainers and coaches are world class. I made the commitment to join about a year ago and haven’t had a single regret since.
I’ve been with x3 since 2016. I like the mixed classes. I have a choice of building muscle with power track or becoming leaner with all the other activities such as kick boxing, fast track etc. The trainers are very approachable and friendly!

Everyone is friendly
