Dear student,
In the 21st century it’s harder than ever to find time and motivation for regular training. Work, school, family responsibilities and daily stress make it tough to commit. And even when you do find time for yourself, how can you be sure you’re training with a truly qualified coach?

If you’re anything like me, you care deeply about who’s coaching you — and what their credentials are.
LOOK NO FURTHER
During my professional MMA career this was my biggest challenge — truly qualified combat-sports experts are rare in Serbia. That’s exactly why I traveled the world to master every area of MMA. After tens of thousands of kilometers, numerous instructor courses, injuries, countless matches across multiple disciplines, and picking the brains of world-class coaches after hours, I finally learned how to train the right way. I was persistent (and yes — a bit annoying), but I wanted that knowledge at all costs and never let anything stand in my way.

All of this could have happened with far fewer injuries — if I’d had a quality mentor while competing. Then again, competitive MMA is a risky activity by nature.

Recreational MMA isn’t inherently high-risk — but with an unqualified coach, the RISK INCREASES SIGNIFICANTLY.
I’ve walked into plenty of gyms where the coaching boils down to “HARDER, SON! HIT!” The goal there is simply to exhaust you, which they consider a “good workout.” Anyone can exhaust a person — you could chase a bus for its entire route and call that “training.” Many coaches never pursue continuing education; they just copy what they learned from their own coaches who also didn’t keep learning. It’s a vicious cycle where the biggest losers are the athletes — both competitors and recreational students. A close friend from my old judo club is devastated that his competitive career fell apart because of poor coaching. He had the will and the work ethic — but no one to guide him properly.
YOU WON’T HAVE THAT PROBLEM HERE

What is MMA and what does it include?

MMA (Mixed Martial Arts — in Serbia often called Ultimate Fight) is a modern combat sport combining multiple styles (Boxing, Muay Thai, Wrestling, Brazilian Jiu-Jitsu, and Judo). You’ll learn the most effective, applicable techniques from these styles through a progressive, methodical curriculum.
Whether your goal is self-defense, fitness, or competition, our years on the mats and with students are your guarantee of the best possible coaching.
WE HAVE A UNIQUE OFFER FOR YOU
Until now, regular groups (we also have an exclusive one) trained three times a week for €180 for six months, paid in advance. Before we present our NEW PAYMENT METHOD, it’s worth noting that many asked why we used that model when no one else offered similar terms.
The truth is, we’re “unusual” here in many ways, and we’ve always aimed to deliver a service at Western standards — because that’s where we trained. Abroad, we regularly attended instructor courses, seminars, competitions, and sparring camps. But “the fight craft” wasn’t the only thing we brought home.
I had the privilege of training for months at one of the WORLD’S MOST SUCCESSFUL AND LARGEST martial arts centers, where I learned how they operate. It’s no wonder they’re so successful — they truly give a lot to their students, just as we do. That’s where we adopted the six-month model because it BENEFITS STUDENTS THE MOST.
What’s so good about our MMA model?
In most gyms, coaches show whatever comes to mind that night. Not here. We offer a linear, structured curriculum designed to instill MMA fundamentals as quickly as possible. Once a group is full, we don’t accept new members for the next six months. The group progresses together through the basics, which dramatically accelerates learning. We don’t add latecomers so current students aren’t dragged back to lessons they’ve already mastered.
A good analogy is a six-month language course. Imagine that four months in, a new student joins and the teacher goes back to spelling — you’d be bored to tears.
We benefit from this model too — the classic American WIN-WIN. Everybody gains.
IF EVERYONE BENEFITS, WHY CHANGE THE PAYMENT MODEL?
Simple — even though €180 averages just €30 per month, not everyone can pay it all at once. We traveled the world to learn from the best, then returned to Belgrade to contribute with our skills — not to limit opportunities.
We care deeply that everyone has the chance to try our program, which many consider the best on the market — so we’ve decided to make it accessible to all.
It’s not just about technical expertise; it’s our entire approach — safety and health first, a friendly training atmosphere, and many member benefits. Too many times we had to turn away highly motivated people because they came mid-season or couldn’t pay the six-month fee upfront.
NO MORE TURNING PEOPLE AWAY!
Because we’re obsessed with finding ways to deliver more, everyone can now train with us. We’re offering several payment options — contact us to learn more.
Only two conditions:
1) Payments must be made by the 5th of each month.
2) Arrive on time and consistently, be respectful, follow coaching instructions, and allow our program to bring out your best.
This program is NOT for everyone.
If you lack the desire to improve yourself, arrive late carelessly, behave disrespectfully, ignore the coach’s guidance, and aren’t ready to reach your potential and work hard — THIS PROGRAM IS NOT FOR YOU.

GUARANTEE #2: A friendly atmosphere — no toxic hyper-competitiveness.
We’re here to train and progress, not to get injured. Despite clichés about MMA “brawls” in training, that is NOT how we work at KAIZEN. We foster a friendly vibe, limit sparring power to ~20% (or less), and always consider each student’s current condition. Injuries are possible in any sport, even the gym, but with our approach the risk is MINIMIZED. Student safety is our #1 priority.
GUARANTEE #3: Better conditioning, physique, and technique.
Follow the coaching and show up consistently — we GUARANTEE PROGRESS. We only wish we had more before/after photos of students who transformed their bodies.
GUARANTEE #4: A 7-day free “test drive.”
Come train with us — completely FREE for 7 days. After that, sign up and pay only if you’re fully convinced we meet ALL your needs.

GUARANTEE #5: 30-day money-back guarantee if you’re not satisfied.
After your 7-day test drive, you’ll have another 23 days to evaluate us. If for any reason you’re not satisfied, we’ll refund ALL your money — and part as friends.
We’re THAT confident you’ll love our program once you try it — you won’t want to stop!
Don’t take our word for it. Come and see for yourself!
