Sebastian has made fitness and bodybuilding his sole passion, but this wasn’t always the case. In fact, when he was a young adult it was boxing that attracted him. He spent a number of years in his local boxing gym learning how to fight, but he loved the strength training side of the sport so much, that he considered quitting boxing and taking up weightlifting.
