Frank has always been very interested in sports. In addition to playing football, and going to swimming practice, he was an ambitious middle and long distance runner where he managed to win many regional championships. Even though he had been training with weight, that extensive cardiovascular workout kept him from building muscle. It would be while he was majoring in sports at university that Frank was able to gather all of the scientific information he needed about training and nutrition. He would later apply all of this learning to his job as a personal trainer. He was able to forego running at that time which became a catalyst for his skyrocketing training success.

It is with his fascination by the adaptability of the human body, and his experience and training, that he is able to push limits every day. Using banned substances is an absolute taboo for him. In his second year as a competitive bodybuilder, Frank became German Champion of the GNBF and Vice World Champion in 2017. By becoming the first German natural Mr. Olympia he has secured himself a Pro Card in the Physique Class.
