Arnold started boxing at the age of five, but then took a break from the sport to play football in highschool. Despite going up to 200lbs in his new sport, Arnold came back to the sport he first loved and turned professional to make noise in the 140lbs division. He has since amassed a 26-0 record and a name as a serious contender as a Super Lightweight.⁠
