Joe DeNucci: “The People’s Champion”

Joe was a professional middleweight boxer, born & raised in Newton, MA. Aside from his outstanding career and status as the record-holder for the most bouts in the historic Boston Garden (23), Joe also held a position as the longest-serving auditor for the Commonwealth of Massachusetts.

Joe passed down his wisdom to the founders of BOXYGEN, and it is here that his legacy and passion for the sport of boxing live on.


The BOXYGEN program is built on the “Fighter’s Will” philosophy, a notion that transcends physical fitness and applies to all aspects of a person’s life, from approaching the simplest of tasks, to conquering difficulties. The “Fighter’s Will” is premised on the fundamental principles that guide competitive boxers: discipline, perseverance, and respect.

All BOXYGEN trainers encourage participants to strive to maximize their potential, while learning and maintaining proper form and technique.
