Ultiminio's passion for sports lead him into fitness. Starting as a full ride scholarship pitcher for the University of Nebraska and then a Golden Gloves boxer, becoming a trainer seemed the natural next step. Through the years, he has trained various fighters, run boot camps, ran the boxing program for The Biggest Loser Resort, and coached for Orangetheory Fitness. When introduced to F45, Ultiminio knew that F45 and he would be a perfect pair. From there, opportunities arose to showcase his boxing training skills at Chicago Athletic Clubs and he loves it all.
