Physical Exercise as Treatment Post-stroke Fatigue - a Feasibilty Study.

The goal of this clinical trial is to evaluate the feasibility the treatment FaStEx (FatigueStrokeExercise) which consists of strength exercise in people with brain fatigue after stroke, referred to as post-stroke fatigue. The main questions it aims to answer are: * What is the feasibility of a study with the treatment FaStEx, structured physical training, for people with post-stroke fatigue? * What factors are important for people with post-stroke fatigue to be able to complete the FaStEx treatment? * How do people with post-stroke fatigue experience participation in the study with the FaStEx treatment? Researchers will compare FaStEx to physical activity at home to see if FaStEx can reduce post-stroke fatigue. Participants will * Carry out strength training twice a week at a health care center. * Carry out physical activity for at least 150 minutes per week on their own. Participants in the control group will carry out this physical activity as well. * The treatment lasts for eight weeks.
