Gladiators NYC is the flagship program for free martial arts and fitness nonprofit Santa's Knights, founded by 40-year-old Damion DiGrazia eight years ago.
Once a month, the group meets up for battle (and a show) in Central Park. Up to four knights fight to the finish, until one is left standing. They punch and throw each other in the dirt, using full-contact mixed martial arts techniques in three one-minute rounds.
