A critical and experimental look at the body, pushed to its physical limit during an oncological process. On the one hand, an exhausted body is presented, worn out by an endless race in the service of a competitive capitalism that demands constant performance. On the other, a body that submits to effort as a tool to analyze the potential of physical exercise in improving the quality of life and the capacity for healing throughout the oncological process. A reflection that explores the tension between wear and tear and regeneration, between exploitation and resistance.
