I've been to several gyms that included Kickboxing or Jiu Jitsu and this is nothing like those. I love the intensity and the challenges of the all of classes and every instructor legitimately know their stuff. Krav Maga is by far one of my favorites. Plus I'm also marathon training and this is by far the best cross training I've ever done.
Training here is a blast. The instructors are knowledgeable and helpful. The classes are fun. The gym is nice. Two enthusiastic thumbs up.
XKM has been a game changer to me. I spent 2 months looking for a kickboxing gym to join and from the moment I walked in and meet Joel's welcoming smile and knowledge, I was hooked. Not only is he knowledgeable about what's going on at XKM at all times but he's also a kick ass instructor. I've made several friends and I look forward to coming in, releasing some stress, shooting the breeze, and the best part, getting an amazing workout and life skill from some of the best instructors I have ever seen.
Great Trainers, Excellent Environment for Learning, Been Training here for a few months and the experience has been wonderful. Top Tier Gym!!!
I've been going here for about 3 months now. The staff have been exceptionally awesome. It's like saying hi to my well known friends every time I go in. The instructors are very knowledgeable. They are really good at demonstrating different skills, and are great at helping walk me through different moves that I struggle with. My kids have been going about a month longer than me. They absolutely love when their training days come up. The kid instructors are great at helping them through learning new skills. They really make a point of giving individualized attention to the kids who struggle and need an extra hand to progress.
10/10, I couldn't more highly recommend this gym
I was looking for a place that offered classes for both myself and my son. XKM provides that, plus, while getting a workout we are learning a life skill, building confidence, and having fun talking about what we learned in our classes at home. The instructors are very knowledgeable and professional. I call XKM my life gym!
Took a class through our gym. Our instructor was phenomenal! The class was fun and informative. I walked away with a few bruises but most importantly confidence!
The new facility in Fenton is fantastic. Multiple different mat/instruction areas. Restrooms, showers, member lounge. The instructors are knowledgeable and every class is not only informative but a good workout for your mind and body. Everyone is friendly from staff, instructors, and other members.
I just joined a couple weeks ago and I couldn’t be happier. All of the staff is extremely friendly, fun, and truly want to see you succeed. Joel is always there to greet you with a smile, and pop in classes to tell people how great they are doing. There is always fun music playing, and you really get in the zone. You jump right into the classes, and people that have already been taking the classes, help you as well. It’s only been 2 weeks and I can already feel my body getting tighter, and have learned awesome self defense moves.
This is a great place- highly recommend!
I’ve been attending the women’s self defense classes for about 2 months. I LOVE them! Alison is a fantastic teacher. There is no reason to be intimidated, anyone can do this. Great workout, empowering, and such important life skills. Every staff member is welcoming. Fenton location is convenient. The workshops are also a great way to preview the space and vibes.
Great people, nice facility. Classes are fun and engaging.
