From the reviews
We have had an amazing experience with Mr. and Mrs. Martinez and their summer camp/martial arts classes. They genuinely care about the kids and do a great job balancing fun with structure, discipline, confidence, and respect.
Great martial arts instructors When I first started very new on doing martial arts. They are really great instructors on teaching me step-by-step of the ways of martial arts. They’re very fun.
Mr. and Mrs. Martinez have been incredible martial arts instructors for my kids. Since training with them, my children have grown stronger physically and gained so much confidence. They create a positive, supportive environment while teaching discipline, respect, and valuable self-defense skills.
My daughter has been training with the Martinez’s for over 5yrs now. They have been amazing instructors and have helped her achieve a lot of her goals. If you want to train with dedicated instructors who have taught and coached fighters/martial artist to an elite level I could not recommend them enough!
New to kickboxing? Start at The KO Nation
The KO Nation comes up as a beginner-friendly gym — noted on their own site. If you've never thrown a punch or a kick, that's exactly who a good beginners class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first kickboxing class at The KO Nation
Nervous about walking into a kickboxing gym for the first time? Almost everyone is, and good coaches 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 the basics — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
