Belgian natural bodybuilder and sports model Erko Jun is one tough dude. Originally from Croatia, 5'10", 185 lbs., 21 year old was a '12 Model Universe™ Championships Top 5 Finalist last June in Miami. Erko credits lifting and the gym for changing his life. "As a youngster I was always on the streets and enjoying the nightlife in a bad way," he admits. "Because of my mentor, I learned to lose my aggression in the gym while working out and keep myself on the right track. This is my second home. The gym that changed my life!" Erko says he's training for Musclemania® Universe and Paris this season.
