And it is necessary to make a Fitness card and a fitness love board so that children with Down syndrome are more excited. The purpose of this study is to establish cooperation between physical education teachers and parents in maintaining the fitness of Down Syndrome children while at home, and to help maintain the fitness of Down Syndrome children during the lock down period this year and in the coming years if there is a lock down period. again. The subjects of this study were 3 Down syndrome students from Special Olympics Surabaya. The design of this research is development research with research instruments in the form of validation sheets and video recordings that will be used to draw descriptive conclusions. The data analysis technique used is descriptive. Product trial validation was carried out by 6 experts who have experience in treating children with Down syndrome and 3 parents of students. The results showed that the average validation score of the experts was 98% and the average validation score of the parents was 98% which was in the very good category.
