Bill Duff — Striking Coach (Kickboxing & Muay Thai)

Calvert MMA: Sharpen Your Striking with a Proven Pro

About Bill

Bill Duff is more than a coach—he’s an athlete and martial artist with a résumé few can match. A two-time New Jersey State Heavyweight Wrestling Champion, team captain of the 1997 SEC Champion Tennessee Volunteers, and former professional defensive tackle in the NFL, NFL Europe (World Bowl Champion), XFL, and Arena Football League, Bill has competed and trained at the highest levels of sport.

Beyond football and wrestling, Bill earned his brown belt in Tang Soo Do and became widely known as the co-host of the History Channel’s hit show Human Weapon, where he traveled the globe training in martial arts like Muay Thai, Karate, Sambo, and more—learning directly from masters of the craft. His career has made him a well-rounded martial artist and striking instructor with worldwide perspective.
