Boxing Training for Men Over 35
For men over 35 who work long hours, sit too much, and want a change:
Give me 3 hours a week and you’ll be fight-ready and in the best shape of your life in 6 months
Even if you’ve never played sports
- Have you always wanted to try martial arts but think it’s “too late” because it’s only for younger guys?
- Worried about the crowd in typical gyms and don’t want to get hurt during training?
- Do you feel your body deteriorating from long hours at a computer and physical inactivity? Do you have back pain from sitting?
- Does it bother you that you stayed silent when you should’ve reacted because you weren’t confident enough?
- Would you like to live a healthier lifestyle, but you simply don’t have the time and you’re constantly tired?
- Are you worried you’ll stop being attractive to your wife/girlfriend?
HOW MODERN LIFE WEARS US DOWN

These days it’s getting harder to live a healthy life and keep even a basic level of fitness. The fast, modern pace grinds us down—especially people who spend long hours in front of a computer and those in corporate jobs.
We can’t start the morning without coffee, we grab whatever food is at hand (usually something quick, just to curb hunger). We stare at screens for hours—at work and on our phones—end up with herniated discs from too much sitting, and when the workday ends we don’t feel like doing anything but going home and relaxing with a beer. Day after day.
On top of that, we feel we’re not the men we used to be. We’ve gained weight, have no energy, and we’ve accepted it as “normal” because we’re getting older.
And then we wonder why we’re run-down?
Can it be different?
Not only can it, but you can be in the best shape of your life and fight-ready in 6 months—whether you’ve trained before or not.
WHY I CAN HELP (ABOUT ME)

You’re probably asking who I am to “lecture” you and why you should listen to what I have to say.
My name is Mark Lajhner, and I’ve spent over 30 years in martial arts and coaching. I can help you get into the best shape of your life through boxing training in just 6 months.
Sound like a stretch? Keep reading and I’ll explain.
In short, I’m a former judoka (national team), later moved to MMA where I went undefeated as a competitor, and I’ve been an MMA coach for over 15 years. I’ve trained thousands of people—competitors and recreational athletes—through my online instructionals, live sessions, seminars, summer camps, both young and older.
You could say I’ve been through the wringer in some of the toughest sports. I’ve gained a lot of experience working with people, and now I want to help men over 35 who’ve always wanted to train martial arts and who want to get in shape.
WHY MEN OVER 35?
I know how men tick because I’ve spent a big part of my life in male sports teams, and I’m over 40 myself.
I also spend a lot of time in front of a computer, so I know what that looks like and the problems it brings.
More importantly, the widely accepted lie that a man over 35 is “old” and can’t do what he used to really bothers me. It pains me to see people in their prime who’ve let themselves go and think that’s normal.
They don’t realize that small adjustments to habits and mindset can make life look completely different.
THE 4 MOST COMMON EXCUSES FOR LETTING YOURSELF GO
Here are the 4 excuses I hear most often when talking to out-of-shape men:
1. AGE (MY TIME HAS PASSED)
2. I DON’T HAVE TIME
3. I DON’T HAVE ENERGY
4. I’M NOT THE “SPORTY” TYPE
Let’s look at each one:
1. AGE (MY TIME HAS PASSED)

One of the most common excuses I hear from men who’ve let themselves go is—age.
I’m not young anymore… my time has passed… I used to be fit… women went crazy for me, but now I’ve gotten old…
Honestly, this is the worst excuse of all.
When I point to men in their 70s and 80s who set powerlifting records, run marathons, or simply look fantastic, the next excuses appear: they’re in America, it’s different there… he’s an actor and has to look good… and so on.
Yes, testosterone levels tend to decline after 30, but you can halt—or even boost—that naturally with training, nutrition, and a healthy lifestyle. You could also use synthetic testosterone, but I don’t support that. More on this later…
To complicate things, older generations had higher baseline testosterone: our fathers more than us, and our grandfathers more than our fathers. More on that later as well.
All my clients are either in the best shape of their lives—or on their way there.
So age can’t be the reason you’re not in shape.
2. I DON’T HAVE TIME

The issue isn’t age itself but the pile-up of obligations we didn’t have when we were younger and more focused on our bodies. We didn’t adapt, and we let those obligations knock us off track.
The truth: you can still build impressive fitness and look great, even if you’re not 20 anymore. You just need to carve out the time.
How, when you go to bed late because you finally get a moment to yourself after the kids fall asleep? With all your responsibilities, who has time to work out—and who has time to cook healthy food?
The problem is we treat training like a necessary evil, so of course we don’t feel like “making time.” Instead, see training as something enjoyable—something you look forward to. Same goes for healthy eating.
In my opinion, starting the day with a morning session is not only the best way to energize yourself—it’s also the simplest way to fit training into your schedule.
3. I DON’T HAVE ENERGY

It’s true you lack energy—but the question is why?
The equation is simple: inactivity + poor diet = more body fat and less muscle. That automatically means lower testosterone, which means less energy. That’s the short version.
Add poor sleep—which also drops testosterone—and you’ve got the recipe for mental and physical decline.
Don’t forget alcohol, smoking, and “self-medicating” with coffee. None of that helps.
Your daily work and family duties do tire you out, sure—but the main culprits are the habits above. That’s the real reason for low energy, and it’s easily fixed.
With consistent training and better habits, the situation flips completely.
4. I’M NOT THE “SPORTY” TYPE

Even if you’ve never been “sporty,” it doesn’t matter—you can start now.
My wife started training at 38.
Don’t treat this as a competition with others—it’s a competition with your previous self. There will always be someone who looks better or is fitter, whether it’s from training or genetics.
The point is to get the best—or close to the best—out of your own genetic potential. Stop comparing yourself to others (unless it motivates you). Focus on how to be better than yesterday.
Will you let these excuses stop you from doing something important for yourself?
You already know you’re not living optimally and that it could be much better.
I can help—if you’re truly ready to change.
Presenting:
THE KAIZEN RECREATIONAL BOXING GROUP FOR MEN 35+ (FOR THE FIRST 6 PEOPLE WHO SIGN UP)
WHAT YOU GET IN THIS PROGRAM—AND WHY BOXING?
Although I’m an MMA coach and teach all the skills that sport includes, there are several reasons I chose boxing:
1. Trainee Safety

It might sound odd to call boxing “safe,” especially if you’ve watched fights—but it is.
If it’s done the right way.
I can’t speak for other clubs, but at Kaizen the goal is mutual progress—not injuring your partner. Even when we spar, it’s very controlled and focused on scoring, not on throwing hard shots at your partner. We save the heavy hits for pads and the heavy bag.
I introduced this approach over a decade ago, and now many professionals in the West train this way as well. For some reason, it still isn’t standard in some Serbian clubs, which is why many people—especially in mid-life—avoid this kind of training.
Student safety is my number one priority.
2. The Best Skill for Real-World Self-Defense

This may be the least important reason for someone like you to start boxing. I don’t condone street fighting unless absolutely necessary—but I must stress that boxing is the most effective in that context, especially against multiple attackers.
Everything in the MMA toolkit can be used on the street, but boxing keeps you balanced on both feet. Kicks put you on one leg, which can make you fall. Wrestling ties you up with one opponent, which is bad if there are several. And ground fighting is also a poor choice in a group situation.
That’s why boxing is #1 for this use case.
3. The Kaizen MMA Striking System + a Teacher’s Approach

Mark training with a renowned Muay Thai coach in Sweden. Smignum is a Rajadamnern and Lumpinee champion (the highest title a Muay Thai fighter can win), a King’s Cup winner, and a 1988 Seoul Olympic boxing competitor.

Mark Lajhner at a Crazy Monkey Defense seminar led by Rodney King, a world-recognized boxing expert — Munich, 2010.
This system was developed in collaboration with some of the world’s top experts and professional fighters. It’s designed to make you fight-ready in the shortest possible time using modern training methods tailored to your fitness level, age, and goals.
Combined with the right pedagogical approach, it ensures you progress as fast as possible.
4. Waking Up—and Using—Your Body

One of the biggest benefits of this program is that your body finally “wakes up.” Sitting and driving to the store aren’t “using your body.”
All day our minds are “somewhere out there” in a screen—at work on a computer or scrolling in our free time. Either way, not in the body. When you stand up after hours like that, you feel like a zombie.
Strength work and running are great (which is why we add them), but they activate your body’s potential only so far—and can even “robotize” you because everything is done in a single plane.
Combat training makes the body smart and forces us to move “in three dimensions.”
You’ll learn to use parts of your body in ways you never imagined—and you’ll feel more awake than ever. Your awareness returns to the body, where it belongs.
5. Conditioning and Strength

The Kaizen boxing program builds conditioning by itself—and we’ll also add strength and endurance work to the sessions. That multiplies the results and helps you feel and look the way you want.
6. Confidence Through a Healthy Relationship With Force

There’s no more authentic confidence than confidence in your physical and fighting ability. You can’t fake it—and it radiates without you trying. It’s not about puffing yourself up or intimidating others. It’s a calm, relaxed attitude that comes from self-assurance.
Women notice it—so do other men.
To quote Canadian clinical psychologist and YouTube figure Jordan Peterson:
“A man can only be good if he’s a monster.”
The point is: a coward isn’t “good” by choice—he’s “good” because he has no other option. A man should become a monster to be truly good. That does NOT mean acting like one, but being capable of force—and choosing self-control.
Through fight training you’ll learn to control anger and turn fear into fuel rather than paralysis.
In the modern world many people are disgusted by violence. Senseless violence is of course bad—but if someone attacks you or your family, either you use force to defend them, or later the police will use force on the attacker. Someone will use force eventually, which makes blanket disgust at force unrealistic.
This doesn’t mean you’ll look for such situations. On the contrary.
I strongly oppose using force except when absolutely necessary.
But if it happens—you’ll know what to do.
It takes two to tango; the more fight-capable you are, the less you’ll feel the need for physical conflict because you won’t feel threatened. You won’t “pour fuel on the fire” in tense situations.
Modern society—especially in the West—often tries to “neuter” men and erase even a trace of aggression. That’s not only wrong; it’s harmful to society as a whole.
A healthy relationship with force doesn’t harm a man—it grounds and ennobles him.
Many clients tell me they’re calmer since they started training—and that’s no surprise. Men have always needed to be physically capable; it’s healthy and shouldn’t be suppressed.
7. Assertiveness

Many corporations run assertiveness trainings. As one of my clients said: “All those trainings are pointless if your assertiveness isn’t backed by fighting skill.”
You’ll sound more authentic when you speak up because verbal confrontation won’t rattle you after hundreds of spars. What’s a disagreement with a colleague or a boss compared to a fist flying toward your face?
8. Training Outdoors

Spending time outside is essential for health. If we’re honest, we don’t do it nearly enough.
That’s why many sessions are held outdoors. Yes, we have an indoor option for bad weather, but whenever possible, we’ll be surrounded by greenery. I most often run sessions in Zvezdara Forest, sometimes on Ada Huja by the Danube—both have a therapeutic effect. Even after 35+ years of training, I’m still thrilled every time I step into the woods, like it’s my first time.
All my clients love outdoor training—some even wish they lived closer so they could come outside of class times.
9. Training in a Group of Men

A man’s natural state is being with other men around a shared goal—hunting in the past, the military, a company, even a crew.
Today we spend most of our time at a computer, with our partner and kids—which can dull the edge and lower testosterone.
Three times a week in a group of men with the same goal, doing hard things together, will revitalize you. You’ll start the day with strong masculine energy—and you’ll progress faster together.
BONUSES
On top of everything you get by joining the group, I’ve prepared extras you’ll find useful:
Online Striking Lessons (for sign-ups by August 15)

Besides live training, you’ll also be able to watch lessons online. You’ll get access to my striking instructional “MMA Striking Made Easy” (in English), which I normally sell for $98.5 to people who want to learn from me online.
Along with boxing lessons, it includes kicking techniques and advanced tactics—if you’re curious to explore them.
This is a hybrid training model that combines in-person and online work. You’ll be seeing me more often than politicians on TV. 😊
Boxing Gloves—Free Gift (for sign-ups by March 25)

More on this further down.
Effortless Weight Loss With a Nutrition Guide

If you’re carrying extra weight and want to drop it, I’ve prepared two simple ways to do it.
Once I explain both methods, you’ll choose the one you prefer—and then let time do its work.
There are tons of diet myths, and people overcomplicate weight loss. These two approaches go to the heart of the issue and—most importantly—deliver results.
Say Goodbye to Lower-Back Pain in 15 Minutes

I’ve had serious back issues that forced me to quit many activities. I have six lumbar disc herniations (+ three cervical), and at one point I couldn’t sit at all—I even ate standing up.
After years of visiting physical therapists, osteopaths, and chiropractors—and testing many rehab routines—I narrowed it down to the essential drills we need to do regularly to stay pain-free.
I didn’t believe I’d ever spar again, but once I identified the best exercises for my back, it didn’t take long to return to sparring.
Most people need just 15 minutes a day to fix their backs.
– Beyond those basics, I’ll show you additional drills if you want even better results.
– I’ll show you why I no longer sit while working and how I built a workstation that lets me stand and lie down while using a computer.
– How often you should get up from the desk—whether your spine is healthy or not.
Scientifically Backed, Natural Testosterone Optimization

Modern life wrecks testosterone levels—and that’s bad news for men. Many turn to steroids; I’m against that.
I’ll show you how to boost testosterone naturally: foods to include, habits and training methods to adopt, and even which plastics to avoid.
Testosterone impacts mood, recovery, libido, and much more. By optimizing it naturally, you’ll feel and look better than ever.
Simple Strength & Conditioning

Here’s what you’ll learn:
– A five-minute strength session. Do it when you’re short on time. Even this alone will build strength.
– A foundational bodyweight (calisthenics) routine. Push-ups, dips, squats, pull-ups, and more. How to structure the plan—sets, reps, and rest times.
– Basic exercises on gymnastic rings. They’re simple, compact, mobile, mountable on a branch or bar—and everything is roughly 3× harder on them. Rings are my favorite strength tool.
– Several ways to do cardio/aerobic work. We’ll cover walking (do you really need 10,000 steps?), running, cycling, swimming—and what’s best for you.
– How to do interval training, why it’s popular, why it works quickly, and why it doesn’t take long.
– Core gym lifts—how to do them and why to stick to them. If you like the gym, I’ll teach you just a handful of movements for maximum effect. The rest you can ignore—they’re mostly time-wasters. You won’t need a personal trainer.
Which Sports Watch/Band to Buy—and Whether You Even Need One

Garmin, Polar, Apple, Fitbit, Suunto, Coros, Huawei, Samsung, Xiaomi… they all make sports/smart watches and bands—but which to choose?
As a tech enthusiast, I’ll show you which models measure heart rate, VO₂, and sleep best; which have the most accurate GPS; which batteries last longest—and more. You’ll be able to decide what fits your needs.
My recommendations won’t be subjective—I’ll summarize what scientific testing says about these brands.
I’ll also explain whether you need any of this to train effectively. And if you’d rather avoid tech, I’ll give you a low-tech way to track the basics.
Mental Strategies for Motivation

We all lose motivation sometimes. That’s normal—but if it happens often or lasts long, it can hurt your quality of life and your goals.
I’ll share several mental strategies that help you regain motivation quickly and get through those dips much faster than usual.
How to Sleep Like a Rock Every Night

Good sleep is one of the most important factors for health—maybe the most important. Without regular, quality sleep, your health, strength, appearance, hormones, mood, and relationships all suffer.
For most people, poor sleep comes from poor lifestyle choices: going to bed late, staring at screens before sleep, waking up drained, and then drowning in caffeine to get going.
I’ll show you simple ways to fix your sleep—and you’ll see a night-and-day difference in your quality of life.
I’ll explain when—and how long—you should nap (when you have time, say on weekends). When and how it backfires, and what the right therapeutic dose is.
One reason I could train 3× a day without steroids or any banned substances was the afternoon nap—and the effect was similar.
Free Physiotherapy Assessment

By joining the group, you’ll also get a free assessment with Andrej, my physiotherapist—for you or a family member or friend, if needed.
If you’ve read this far, it’s clear this isn’t a typical program. It’s built for someone exactly like you, and I’m confident you won’t find anything similar elsewhere in Serbia—probably not abroad, either.
I’ve spent over $50,000 traveling the world learning from the best. I paid with multiple injuries, surgeries, and years of physical therapy.
I suffered so you don’t have to.
You can get my experience for a fraction of what it cost me to acquire it.
Like a sculptor who sees the figure inside the stone, I see your potential—who you can be and how you can look—once you’re guided the right way.
It’s not “too late” to start boxing; it will change your life and enrich you as a man.
IMPORTANT:
The group is limited to 6 people. The program lasts 6 months, and I don’t know when the next intake will be. If you don’t secure a spot now, I’ll put you on the waitlist and notify you when the next group starts.
If you sign up by July 15, you’ll receive the “MMA Striking Made Easy” instructional and a pair of boxing gloves as a gift—together worth over $100. I want to reward the most committed men who truly want to change their lives.

AN INCREDIBLE EDUCATOR

Dynamo Kettlebells
Mark Lajhner is one of those rare figures in the world of martial
arts where an elite-level athlete evolves into an exceptional coach.
I’ve been working on improving athletic performance for years, and my
main focus is developing the most effective teaching methods to speed up learning in combat sports athletes, so it’s pretty hard to impress me with an instructor’s teaching skills. However, when I visited Mark’s Kaizen MMA Academy and had the chance to train there, I was amazed at how incredible an educator Mark is.
He explains techniques with the right balance of explanation and
demonstration, breaks them down into component skills, and progresses
gradually from easy to hard, simple to complex, familiar to new. The
result is something I’ve rarely seen in my twenty-five years of training martial arts: everyone seems to absorb the knowledge while also understanding the point!
If you want to build your MMA skill on a solid foundation that allows
you to keep improving, I’d say you can’t do better than training with
Mark in person, either at the Kaizen MMA Academy or at one of his summer camps. You’ll be surprised how good you can get at MMA — I guarantee it!
MARK TOOK MY SKILLS TO THE NEXT LEVEL

Art Storefronts – Technical Support Team Lead
I started my martial arts journey about 8 years ago at Mark’s MMA
Academy. What drew me in was the vast MMA knowledge Mark possesses and the impeccable way he transfers it. Over the years, I’ve trained with different coaches in different disciplines, but I found Mark’s system the easiest to understand and apply. MMA is a complex sport and requires an extremely skilled and experienced person to teach it the right way — Mark definitely is that person.
Training with Mark took my game to a higher level, brought me several amateur gold medals, and gave me incredible experiences. If you want to start your martial arts journey, get fit and strong, Mark is one of the best coaches to guide you.
Price
Small exclusive group
240 per month
Why is the program 6 months long?
While you’ll notice improvements within just a month, I need at least 6 months to create a tangible change in your fighting ability, fitness, confidence and overall look.
SCHEDULE & LOCATION
Training sessions are held on Tuesday, Thursday and Friday from 8–9am at the gym by the OFK Stadium, or outdoors at the Zvezdani Gaj kindergarten court in Zvezdara Forest.
MONEY-BACK GUARANTEE

What if you don’t make progress?
It’s no accident my proven system has helped hundreds of men become the best versions of themselves. Still, there are always a few for whom it simply doesn’t work.
Best case scenario:
In 6 months you’re unrecognizable. Your friends are impressed (some even jealous) at how far you’ve come, you feel confident and powerful, you’re showing your son the basics of boxing and he looks up to you like a hero, and you’re more attractive to your girlfriend or wife.
Worst case scenario:
As much as I’d like to, I can’t help everyone. If you feel my program hasn’t delivered any results after one month, and you’ve attended at least 2/3 of the sessions, send me an email and I’ll refund 100% of what you paid — no questions asked.
We’ll part as friends; you keep the videos I sent you, the gloves, and everything you learned.
I have a feeling that won’t be the case if you train properly and follow the rest of the guidance.
I’m not asking you to decide today — only to make a fully informed decision. The only way to do that is from the inside, not the outside.
So, join the group and see whether everything I wrote here is true and valuable for you. If it is, then decide to continue. If it’s not for you, no hard feelings.
You can’t make this decision now for the same reason you wouldn’t buy an apartment without first seeing the inside.
And know this… whether it’s 30 minutes or 30 days from now — if you’re not happy, I’m not happy. For any reason, if you want your money back, you can get it, because I want to keep your money ONLY IF YOU’RE SATISFIED.
All you need to do is call me at 064/1128-456 or email info@kaizenmma.com and write: “refund my money.” You’ll get it quickly — my average response time to any support request is 61 minutes across a 24/7 period.
I can offer this guarantee only because I’m confident what you’re getting is the real deal, and I’m quite sure that once you sign up and make the payment, you’ll get exactly what will benefit you greatly.
P.S. I won’t insult your intelligence by saying it will take just two weeks or something like that. No — on average you’ll need 6 months to significantly improve using my system. If you also do the extra work from the bonus section, you’ll progress even faster.
Once you get in shape and become combat-ready, expect a few snarky comments from some friends out of jealousy like, “Who do you think you are, Rocky Balboa?”
They’ll actually regret not doing it themselves while they sit on the couch eating chips — and women will regularly be surprised when you tell them your age, thinking you’re younger.
Your other friends will admire the transformation you achieved.
To borrow a metaphor from The Matrix: you can choose the blue pill or the red pill.

Keep taking the blue pill and living your old life. Your back will hurt more and more, you’ll settle for excuses like “it’s just age,” and things will keep getting worse.
Choose the red pill, watch yourself progress month after month and finally become the man you were born to be — strong, confident, and great-looking.
Time will pass either way, and if you don’t sign up now, in 6 months you’ll regret not doing it, while others will already be combat-ready, self-assured and changing their lives.
So don’t hesitate — apply now.
