My name is Nat Miller, and I have been a part of the Rumble Boxing Universe since 2018—that’s when I took my very first class at the Rumble Boxing Chelsea studio.
I had dabbled in boxing before, but this was different. The lights, the beat drops, the sound system, the electric energy—all with a trainer front and center. I was hooked.
Fast forward to today, and I am a Head Trainer at a Rumble studio in South Florida. I’ve been lucky to guide countless people through their own transformations, helping them push past limits they didn’t know they could break. Every class, I see the same story: someone walks in unsure, maybe even intimidated, and walks out standing taller, grinning ear to ear. That’s the power of boxing. That’s the magic of Rumble.
A few months ago, a friend and fellow Rumble trainer, Sean Powers, told me about an opportunity to potentially fight for Haymakers for Hope—a non-profit that organizes charity boxing matches where every dollar raised goes toward cancer research, awareness, and supporting those affected. It wasn’t the first time I’d heard the name. A few years ago, while I was living and working in NYC, I watched Rumble founder Noah Neiman step into the ring for Haymakers. That planted a seed in me. When the chance came around, it was a no-brainer. I said yes without hesitation.
This fight wasn’t just about boxing anymore. It was about purpose. It was about stepping far out of my comfort zone to raise money for a cause that touches so many lives. Training for the fight meant over three months of intense work. But it reminded me of why I do what I do every day at Rumble—to help people tap into their inner power. Now, it was my turn to live that truth on a whole new level.
On fight night, I stepped into the ring and walked away with a unanimous decision win—but more importantly, I raised over $8,675 for the fight against cancer.
Boxing changed my life, and through Rumble, I’ve seen it change the lives of so many others.
Even if you’ve never thought of yourself as a “boxer,” I urge you: try it.
Rumble makes it accessible, welcoming, and powerful in all the right ways.
If you’re looking for something more than a workout—something that challenges you, uplifts you, and makes you feel like an absolute badass—step into the room.
You might just find your own fight.
TOTAL RAISED: $8,675.49
