Actor Felix Kammerer underwent an intense physical transformation, gaining nearly nine kilograms of muscle for his role as Olympic rower Hans Lenk in the upcoming sports drama film Adams Acht, which is set to premiere in German cinemas on September 17, 2026.

Inside Felix Kammerer’s Physical Transformation for Adams Acht
Transforming into an elite athlete requires a meticulous regimen. To authentically portray Olympic rower Hans Lenk, Kammerer pushed his body to the absolute limit. According to an interview with the Neue Osnabrücker Zeitung, the 30-year-old actor admitted, “Ja, ich hatte zum Schluss fast neun Kilogramm extra drauf.”
Achieving that kind of muscle mass on a strict timeline is no small feat. Kammerer detailed a grueling daily routine that involved professional nutrition coaching and intense physical workouts. He noted that he spent months eating protein powder “wie ein Wahnsinniger” to build the requisite bulk.
That preparation was essential for the demanding production schedule. The actor had to maintain peak physical form to handle weeks of rigorous filming inside an original rowing shell, capturing the authentic grit of competitive rowing.
Bringing the Legendary 1960 Deutschland-Achter to the Screen
Adams Acht tackles one of the most celebrated moments in German sports history: the dramatic gold-medal victory of the “Deutschland-Achter” at the 1960 Summer Olympics in Rome. Historical sports dramas live and die by their authenticity. When filmmakers cast actors to portray legendary athletes, audiences expect a level of physical realism that CGI simply cannot fake.
By putting his body through an extreme bulk and conditioning cycle, Kammerer ensures that the physical toll visible on screen matches the historical reality of Olympic-level endurance. As the September 17 theatrical release approaches, anticipation is mounting to see how this intensive physical prep translates to the big screen.
