Member Testimonials
I love the classes
Wish yall had a kickboxing class for 12 and under.
I love the privacy and exclusivity of X3’s boutique nature. I feel like I can get more out of my fitness in the intimate setting.
X3 N Marietta is the perfect blend of a family gym and a fight team center. Open and welcoming, with knowledgeable and dedicated coaches.
It was an easy experience and the price is just an outrageous value, especially for young ones.
The level of knowledge and experience the trainers have.
The community is amazing, anytime you need help there is someone there.
Good environment and equipment, friendly staff that is very helpful and great trainers.
I love the atmosphere and the teachers along with their training style and quality. X3 has always been my favorite gym, now if only I can get one in Decatur or stone mountain so I don't have to travel 1 Hr plus in order to train 😅 (Marta sucks and I stay closer to highway 78, so it's a bit of a travel, but worth it)
Great staff and super energy in classes.
I love the community and support aspect of this gym. I’ve been to other places where it’s every person for themselves, but here it’s welcoming and encouraging vibes only.
I like the ability to take different classes and the hard work atmosphere
Love the fast track classes by Olivia. Also doing personal training with her and she is targeting all of my goals!
Very professional .
Great trainers and classes
I had a great experience at the Marietta location. The staff was friendly and the atmosphere was very welcoming. Nick ensured that everything I had everything I needed and was very helpful in me set up my membership.
It has something for everyone. Staff seems genuinely in to fitness and helping people reach for their goals.
The staff and all of the coaches are very welcoming and friendly! I feel so encouraged to try something new when I go in!
It’s exactly what I’ve been looking for from a gym
I like the feeling of being back in a gym where everyone is working hard and bettering themselves while maintaining a sense of respect for others.
I’ve enjoyed how friendly the staff is and the teachers are always willing to answer questions and help with technique. I’ve also really enjoyed meeting new friends and likeminded folks with fitness goals similar to (or more intense than) mine.
It’s been a good experience so far! I like my coaches for kickboxing specially coach Rica and I love my personal trainer Olivia, she is amazing! Everyone seem to be in the same page and I like the encouragement I get when I feel I cannot do something. It’s my first time kickboxing and I feel like I’m getting the help I need to get where I want to be.
Different instructors bring something different to each class. I can gain different experiences from kickboxing classes taught by different instructors.
Excellent round-based training sessions with a well-balanced emphasis on cardio, technique and strength
The classes are great
Great trainers and atmosphere!
Great environment! I asked a staff member about my shoulder he proceeded to demonstrated how I could relieve the pain while another member present showed what he also did to help with his shoulder pain. Unity is important. It gave me a sense of community.
