Is Rick Tew’s Ninja Gym Koh Samui Worth It for Kids?
Yes. Rick Tew’s Ninja Gym inside Big C Bophut is one of the most genuinely useful kids’ activities on the island. Drop-in group sessions cost 350 THB per child, no booking required, and the 50-minute structured classes cover climbing, balancing, rolling, and obstacle challenges with a dedicated coach. It’s open daily from 9 AM to 9 PM. Our girls (aged 3.5 and 7.5) both loved it, and it’s now our Saturday morning ritual.
We’ve been living in Thailand since 2019. After spending years in Koh Phangan, we recently moved back to Koh Samui with our two girls, Lila (7.5) and Ruby (3.5). One of our favorite things about moving? Exploring every new place on the island—especially anything fun, active, and family-friendly.
Rick Tew’s Ninja Gym Koh Samui wasn’t even on our radar. We were just popping into Big C Bophut for some groceries when we saw it. Bright blue mats, climbing walls, ropes, and a full ninja obstacle course right there on the ground floor. My girls spotted it first and were begging to go in.
In this guide, I’ll share everything you need to know about the Ninja Gym—what it is, how much it costs, what to expect, and why we keep going back.

What Is a Ninja Gym, Exactly?
Rick Tew’s NinjaGym is a training space that mixes martial arts, movement, and mindset. There’s a big focus on coordination, balance, and building confidence through fun physical challenges.
It was created by Rick Tew, a martial arts instructor with decades of experience.
At the Ninja Gym, kids get to move their bodies in all kinds of ways—climbing, rolling, balancing, jumping—while learning to focus, stay calm, and push through challenges. No strict drills or shouting coaches. Just a safe and supportive space to try new things and get stronger in the process.
Rick calls his method Winjitsu. It’s about training the mind as much as the body. So yes, it looks like a bunch of fun obstacle courses—but it’s also a way to build resilience, patience, and confidence.

You can drop in anytime during those hours for a session, or sign up for one of their longer programs.




Our First Visit: Totally Unplanned
We didn’t book in advance. We just walked up, and a young guy named Cat greeted us with the friendliest energy. When he asked if the girls wanted to join the next group session (a 50-minute ninja training class), they didn’t even hesitate.



We paid 350 THB per child for a drop-in group session. That’s 700 THB total—and for what you get, I think it’s super fair.
They also have packages available if you plan to come regularly. But more on that later.
Bonus tip: You don’t need socks. We all went inside barefoot, and it was perfect.
What Happens During a Ninja Training Session?
The kids start with a warm-up. Lots of stretches, body movements, and jumping. Cat was great at showing both Lila and Ruby what to do—even adjusting things for their different ages and energy levels.

Then came the real ninja stuff. There’s a variety of obstacles spread across the gym:
- Climbing walls
- Ropes
- Foam blocks of all shapes and heights
- Wobbly balance balls
- Tires to crawl over
- Slings to swing through
- And of course, a trampoline to launch off
It reminded me of American Ninja Warrior (do you remember the show from the early 2000s?!), just designed for smaller humans.
Lila took to it fast. She was balancing, jumping, climbing—all with this massive grin on her face. Ruby, being smaller, needed more help. But Cat was right there with her, guiding her through every challenge with so much patience.


And then, 50 minutes were up. They came back to me sweaty and happy.
They were so proud of themselves, and each got a ninja sticker as a reward.
What I Loved as a Parent
You’re not allowed on the mats. At first, I thought this would be a pain, but turns out—best rule ever. Kids actually focus better when we’re not hovering.
I waited in the front area where there were tables and chairs. So I got 50 minutes of laptop time while the girls trained like mini ninjas.
Also good to know: there’s a small game room on the side with board games, table soccer, Xbox video games, and some LEGO.

Why Is Ninja Training Good for Kids?
It’s not just a way to burn energy on a hot summer day (though honestly, it’s great for that too). All the jumping, rolling, and climbing actually have a lot of benefits:
- Improve balance and coordination
- Build strength and stamina
- Boost focus and confidence
- Learn patience and discipline
Is It Worth It?
100% yes.
It’s a great way to get your kids moving, thinking, and feeling good. And honestly? It’s one of the most unique experiences we’ve had on the island in a while.
Compared to the usual soft play areas, this feels more purposeful. More active. Less chaos, great guidance.
Plus, now it’s our weekly tradition. We go every Saturday morning to have a great start to the weekend.

- From $136 (€125) per night (Family Room with Bunk Beds)

Who Is the Ninja Gym Best For?
The short answer: kids aged 3 and up who have energy to burn. Our girls are 7.5 and 3.5, and both got something out of it, even though Cat had to adapt the obstacles quite a bit for Ruby.
It’s a great fit for:
- Kids who find traditional sports too rigid or too competitive
- Shy kids who do better with one-on-one guidance (the private session is ideal for this)
- Active kids who just need to MOVE
- Families living on Samui who want a regular weekly activity
I’d say the sweet spot is probably 4 to 10 years old, but older kids and even adults can book sessions too.
