From the reviews
Can't say enough good things about Relentless MMA & Fitness. Coach Dave is the best instructor I've ever had (and I've had A LOT). It took me 40 years to finally find a place and instructor who makes me actually want to come to class and smile while I'm there!
Where do I start. Dave Carter at Relentless MMA is hands down ( I know coach keep my hands up ) the best coach I have had in my 20 year sports career; soccer, lacrosse. I was a bit nervous going into the gym, not knowing what to expect.
I have always hated going to the gym to work out, but training Muay Thai at Relentless has been an wake up experience for me. I have no major intentions of fighting matches, but cutting weight and building some muscle tone ARE my goals. Learning to effectively defend myself form harm is just a big plus.
I find it hard to express in words how great this gym is. Coach Carter is very knowledgeable and explains new techniques in a ways that are easy to understand. His knowledge extends past the violence. He has helped me with diet plans and he has personally helped me rehab my knee after surgery.
New to Krav Maga? Start at Relentless MMA & Fitness
Relentless MMA & Fitness comes up as a beginner-friendly school, going by their listing and students’ reviews. If you've never thrown a punch or set foot in a self-defense class, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or athletic to start — you get in shape by training, not before it, and instructors scale the intensity to you. Second, you won't be thrown into hard sparring — reputable schools build the fundamentals (stance, movement, and core self-defense techniques) over weeks, and controlled pressure-testing eases in gradually so every drill stays safe. Third, all levels really are welcome — ask about a dedicated beginners or Level 1 class time so your first session is alongside others who are also just starting out. Most schools are happy to let you watch or try a class first, so reach out before you commit.
Your first Krav Maga class at Relentless MMA & Fitness
Nervous about walking into a Krav Maga school for the first time? Almost everyone is, and good instructors expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling a few core techniques with a partner — controlled and at your own pace, not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move in — there's no uniform or special gear you need to buy to get started. What to bring: water and a mouthguard if you have one — most schools have everything else you'll need for a first class, so it's worth asking when you call what to bring. Pressure-testing eases in gradually, once your fundamentals are solid — you won't be sparring hard on day one. Arrive 10–15 minutes early to sign in and meet the instructor. It gets easier fast — most people feel far more at home by their third class.
