The work finds its anchor in Heiner Müller’s one-act play *Herzstück*, whose motifs serve as a starting point for further exploration and the development of a unique performance language. The piece emerged through a process of improvisation, collaborative discussion, and the investigation of materials.

At the core of the performance are characters engaged in an imagined discipline—akin to athletics, but focused on the heart. Through this pseudo-scientific practice, affect is treated as a material that can be trained and directed.

The performance unfolds at the intersection of physical expression, philosophical inquiry, and a pseudo-scientific framework. In this process, the performers become "heartletes"—training their own (and others') affects—and constructing a performance space that exists between control and vulnerability. The project explores "heartfulness" (or having heart) as both a state and a practice—an act of attempted rebellion in an era of emotional numbness.
