Meet Coach Bill Duff

Striking Coach (Boxing • Kickboxing • Muay Thai)

Real Experience. Real Coaching. No Ego.

Some instructors teach striking.

Bill Duff has lived it.

At Calvert MMA Academy®, Bill brings a level of experience and perspective that is hard to find anywhere—combining professional athletics, global martial arts training, and years of hands-on coaching into a program designed to help you improve quickly and train the right way.

A Background That Speaks for Itself

Bill’s journey started at the highest levels of competition.

• Two-time New Jersey State Heavyweight Wrestling Champion
• Team Captain of the 1997 SEC Champion Tennessee Volunteers
• Professional Defensive Tackle in the NFL, NFL Europe (World Bowl Champion), XFL, and Arena Football League

But what makes Bill different isn’t just where he’s been.

It’s what he’s continued to learn.

As co-host of the History Channel’s Human Weapon, Bill traveled the world training in disciplines like Muay Thai, Karate, Sambo, and more—learning directly from masters of each system.

That experience gave him something most coaches don’t have:

a global understanding of how striking actually works.

What It’s Like to Train with Bill

Bill is not a “celebrity coach.”

He’s hands-on. He’s engaged. And he genuinely cares about helping people improve.

His classes are:

• structured but approachable
• technical without being overwhelming
• challenging in the right way

You’ll work hard—but you’ll understand what you’re doing and why.

That’s what keeps people coming back.

Striking That Actually Makes Sense

Every session blends Boxing, Kickboxing, and Muay Thai into a complete system that works for:

• beginners with zero experience
• Jiu-Jitsu students improving stand-up skills
• athletes looking for conditioning and performance
• experienced strikers refining technique

What you’ll develop:

• Stance, balance, and footwork that keep you in control
• Clean punching mechanics and combination work
• Kicks, knees, and elbows with proper technique
• Defensive awareness—slips, checks, blocks, and counters
• Timing, distance, and composure under pressure
• Conditioning that carries over into every part of training

The goal isn’t just to hit harder.

It’s to move better, think faster, and stay composed.
