In boxing, strength and skill are essential — but they are never enough. The ring is a mirror. It exposes everything: your discipline, your fears, your character. That’s why only a few ever make it to the top. Not because they lack talent — but because most are derailed by choices, distractions, or the inability to endure the grind that greatness demands.
This is the world that 369 Sports & Entertainment and the legendary 5th Street Gym have committed themselves to — not just building fighters, but forging men.
The Mind Behind the Gloves
Behind 369 Sports & Entertainment is Robert Mazin — a former professional hockey player who represented the Latvian national team at the world championships as well as played professionally around the world. After retiring from the ice, Robert dedicated himself to mentoring elite athletes through mental performance, strategy, and structured discipline. His experience as a pro gives him rare credibility: he doesn’t manage from the sidelines — he leads from the trenches.
In close partnership with world-renowned boxing trainer Dino Spencer, Robert has helped build a training pipeline rooted in resilience. Together, they focus not just on creating winning records — but on raising grounded, mentally conditioned athletes who can survive the noise and endure pressure without breaking.
They believe that boxing isn’t just about how hard you hit — but how deep you’re willing to go when no one is watching.
Their mission is clear: create fighters who can resist the nightlife, the quick highs, the distractions — and instead embrace structure, struggle, and self-mastery.
5th Street Gym: A Breeding Ground of Champions
Located in Miami Beach, 5th Street Gym is one of the most iconic boxing gyms in the world — the same building where Muhammad Ali trained under Angelo Dundee. Over the years, it has also been home to legends like Sugar Ray Leonard, Noel Mikaelian, and countless champions from around the globe. It’s not a flashy gym. It’s a fortress of fundamentals — a sacred ground where greatness is earned, not given.
At the core of Dino Spencer’s modern-day program is something most fighters dread: track work.
Track Work: Where Champions Are Built
Dino’s sprint and endurance training program is not for the weak-minded. It’s brutal. It’s unforgiving. And it’s where he separates those who want to win from those who say they want it.
“Anyone can hit pads,” Dino says. “But go run 800 meters in under 3 minutes — after sparring, in Miami heat. That’s when I see your lungs, your legs, and your heart.”
For Dino, track work is more than cardio. It’s psychological warfare. It kills excuses. It strips away ego. It shows who’s ready — and who’s just talking.
The Cost of Weak Choices
As both Robert and Dino have seen time and time again, it’s rarely the opponent that ends a fighter’s career. It’s the nightlife. The distractions. The bad decisions made off the clock.
“Most fighters lose the fight before the bell even rings,” Robert says. “They lose it when they hit snooze. When they start chasing highs instead of routine.”
The Journal of Clinical Sport Psychology backs them up: athletes with poor emotional regulation and weak goal structures burn out at double the rate. Discipline and structure aren’t optional — they’re lifelines.
The Example: Nikolay Shvab, “ICEMAN”
A living example of 369’s approach is Nikolay Shvab, a rising Kazakh prospect known as ICEMAN for his emotionless, calculated style. Under Robert Mazin’s management and Dino Spencer’s guidance, Shvab has built not only an undefeated record — but a reputation as a cold, clinical professional who treats boxing as a lifestyle, not a show.
He does the roadwork. He lives clean. He listens. He executes. And above all, he doesn’t flinch.
Brotherhood in the Ring
The partnership between Robert and Dino isn’t a business arrangement — it’s a brotherhood forged in sweat and truth.
Robert still trains regularly. He spars. He runs. He eats clean. He lives the same lifestyle he expects of his fighters, which is why his mentorship resonates so deeply.
“There’s no ego,” Dino says. “Robert doesn’t come from the sidelines — he comes from the grind.”
Together, they’ve crafted a new blueprint: build the mind, build the habits, and the wins will follow.
A Conversation on Masculinity and Mentorship
This philosophy runs deeper than just sport. In a recent podcast on the 369.ent YouTube channel, Robert and Dino explored something rarely discussed in fight sports: the shaping of modern masculinity.
They touched on emotional control, the importance of setting boundaries, the role of fathers, and how boys today are rarely taught how to carry struggle.
“Discipline is freedom,” Robert said. “And if we don’t teach our boys how to handle adversity, they’ll collapse under comfort.”
This isn’t macho posturing — it’s survival strategy in a world that rewards distraction and punishes self-control.
The Science Behind the Philosophy
Their approach isn’t just tough love — it’s backed by data. A 2023 Frontiers in Psychology meta-analysis found that athletic longevity is most strongly correlated with three traits: emotional regulation, long-term goal orientation, and resilience under adversity.
These traits can be coached — but only when there’s real mentorship, structure, and accountability. That’s what 369 Sports & Entertainment and 5th Street Gym provide.
The Future of the Fight
In the end, most fighters won’t make it. Not because they weren’t talented — but because they couldn’t stay disciplined. Couldn’t stay focused. Couldn’t stay hungry when the world offered comfort instead of struggle.
But for the few who embrace the silence, the roadwork, and the pain that comes with purpose — a different life awaits.
Because titles fade. But character never does.
