Results from pilot studies indicate that palliative cancer patients report increased well-being and less fatigue after physical activity. This study aimed to explore how palliative cancer patients experienced physical activity. A qualitative design with semi-structured interviews was used. Eleven palliative cancer patients over 18 years old with different diagnoses and Eastern Cooperative Oncology Group Scale performance status levels of between 1 and 3 were interviewed. Four main themes emerged: routines of everyday life, less fatigue, professional guidance, and hope. The first theme comprised two categories: something to do, and being together with others in a similar situation. The theme professional guidance also comprised two categories: the physiotherapist as tutor, and the physiotherapist as motivator. Some cancer patients in palliative care who participated in physical activity experienced less fatigue and enhanced energy. Physical activity helps to bring structure to everyday life and gives a feeling of hope for the future.
