Is Core Strength Martial Arts Right for a Grade-Schooler? A Fitness-First Program Compared

Your nine-year-old has energy to burn, and you’ve been looking at Core Strength Martial Arts kids classes because the name promises exactly what he seems to need. Strength, sweat, and a place to put all that motion. Before you book anything, you want to know whether a strength-forward program is the right match for a grade-schooler.

It can be. For some kids, it’s the best fit in town.

I run a competing school, so read this with that in mind. Every fact I use about Core Strength Martial Arts comes from its own public website, and where its site doesn’t answer a question, I’ll tell you that plainly.

What is Core Strength Martial Arts and who is it for?

Core Strength Martial Arts is a family-owned taekwondo school at 4848 E. Cactus Road in Scottsdale, led by Master Michael C. Wykoff, a 6th degree Black Belt in traditional WT taekwondo.

Here’s what its own pages show. Its instructors trained at the school from white belt up and complete a six-month instructor program before teaching. One of them, Master Zachary Peel, is listed as a 2018 national sparring champion.

Kids train by age in three groups: Little Dragons for ages 4 to 6, Warriors for ages 7 to 10, and Gladiators for ages 11 to 14. The school also lists karate, MMA, Brazilian jiu-jitsu, and grappling, along with a Friday Night Fight Club for ages 4 and up.

The site names the traditional tenets of taekwondo, including courtesy, integrity, perseverance, and self-control. What it doesn’t describe is how a typical kids class divides its time, so I can’t tell you how much of the hour goes to conditioning.

The name, the sparring champion on staff, and the MMA and grappling offerings all point toward a physically intense, sport-forward program. That’s a fair reason a parent might look at it as the fitness choice, and it’s worth asking the school directly how they’d describe themselves.

Is a fitness-focused class good for a grade-schooler?

Yes. A martial arts class that gets a grade-schooler sweating hard a few times a week is doing something most American kids badly need.

The national numbers are sobering. The 2024 U.S. Report Card on Physical Activity found that only about 20% to 28% of American kids ages 6 to 17 get the recommended 60 minutes of activity a day, and it gave the country a D-minus (Physical Activity Alliance, 2024).

Most of those missing minutes go to sitting. School, homework, and screens can fill a child’s whole afternoon, and a program that turns one of those hours into kicks, sprints, and sparring is a real win.

Some kids thrive on exactly that. The athletic nine-year-old who loves to compete, wants to feel strong, and lights up when the drill gets hard will often stay with a fitness-heavy program for years.

What does fitness-first training leave out?

A program organized around fitness has no built-in plan for the child who needs self-control more than cardio.

To be clear, I’m talking about fitness-first programs in general here, since Core Strength’s site doesn’t spell out how its classes are built. When fitness is the organizing goal, progress gets measured in reps, speed, and endurance. Those are good things, and they’re easy to see.

Now picture a different nine-year-old. He’s plenty fit, and he can run all day. His trouble is that he melts down when he loses, shoves when he’s frustrated, and can’t wait his turn.

More conditioning won’t fix that. He needs a program that defines self-control, practices it on purpose, and won’t promote him until he shows it.

Research backs this up. In one study, elementary students randomly assigned to martial arts training focused on self-regulation improved more than a regular PE group in self-control, prosocial behavior, and classroom conduct (Lakes & Hoyt, 2004; verify before use). The PE kids moved too. What set the martial arts group apart was the self-control built into how they trained.

Before I opened a school, I was an aerospace engineer. In that field, you learn that a part’s strength is a side effect of good design. Fitness works the same way in a child. It comes along with good training, and it makes a poor blueprint for building character.

How does a character-organized curriculum differ?

A character-organized curriculum treats self-control, focus, and respect as skills to define, practice, and test at every belt, with the physical work built in around them. 

My doctorate is in special education, and one of the first rules in that field is that you can only teach a behavior you can see and measure. “Be good” is a wish. “Hold your stance without moving while the instructor walks the line” is a skill a seven-year-old can practice and an instructor can check.

Here’s what that looks like at our school. Every class works on a character skill alongside the kicks and stances, such as waiting for the command, stopping a technique short of a partner, or restarting a form calmly after a mistake. Each skill grows over months, and each one shows up at a belt test, where your child has to demonstrate it under a little pressure.

The physical work stays demanding. Our students sweat through pad drills, stances, kicks, and bodyweight strength work, and they leave tired. The difference is that the hard work serves a larger goal, and the child knows it.

As students grow, the same structure carries them into leadership. In our Beyond Black Belt track, older students learn to teach drills and lead younger kids, which is self-control turned outward.

I founded KarateBuilt in 1995 and designed this curriculum myself. Over thirty-plus years, we’ve trained more than 18,000 students and produced more than 1,800 Black Belts, and our school has been named Go2Karate Nation’s #1 Martial Arts School eight consecutive times.

Which program fits which child?

Core Strength Martial Arts is likely the better fit for the athletic, competitive grade-schooler who already handles frustration well and wants hard physical training, sparring, and maybe some MMA or grappling.

If your child dreams of competing, loves contact, and needs more outlets than structure, a sport-forward program like theirs can be a great home. For North Phoenix families who live near Cactus Road, it may also be the closer school, and that convenience adds up over years of weekly classes.

KarateBuilt is the better fit for the child who needs self-control as much as strength. That includes the impulsive kid, the one who melts down after losing, the sensitive kid who needs a steady on-ramp, and any Cave Creek family that wants a curriculum organized around character from the first day.

Here’s a quick side-by-side:

What should a parent ask on a first visit?

Ask questions that reveal how a school spends the hour and what it expects your child to show, then watch a class to see whether the answers hold up.

Bring these five to every school you visit, including mine:

• “How does a typical kids class divide its time between conditioning, technique, and character work?“
• “Besides technique, what does my child have to show to earn the next belt?“
• “What happens when a child loses control or melts down in class?“
• “Who designed the curriculum, and how often does that person teach?“
• “How do you help a child who struggles to focus?“

Then sit along the wall and watch a beginner class. Wait for a child to get frustrated, and see what the instructor does in the next thirty seconds.

New students at KarateBuilt start with two weeks FREE plus a free uniform, a $199 value, at 29850 N. Tatum Blvd., Suite 105, Cave Creek, AZ 85331. Write those five questions on your phone tonight. Then call or text (602) 737-2098 to book a class and ask us every one of them.

Frequently Asked Questions

Does KarateBuilt also build fitness?

Yes. Every class includes vigorous drills, kicks, stances, and bodyweight strength work, and fitness builds right alongside skill and self-control.

How far is Core Strength from Cave Creek?

Core Strength is at 4848 E. Cactus Road in Scottsdale, south of the Loop 101. Enter both addresses in your map app for a weekday afternoon at your child’s class hour to see the drive each way.

My child is already in a sport. Is martial arts redundant?

Usually it adds something new. A team sport builds fitness and teamwork, and martial arts trains individual self-control, self-defense, and a belt path your child owns, so many of our students play other sports too.

What age should a child start?

Many children start between ages 4 and 7. KarateBuilt’s preschool program begins at age 3, and Core Strength’s youngest group starts at 4.
