The primary objective of this research was to create a model of Buyung gymnastics in gross motor learning in early childhood. Methods: This study included 5 material experts and 2 nationally licensed gymnastics experts, 2 early childhood education teachers, and 1 doctoral lecturer with early childhood evaluation and learning expertise. This study also made use of several documents. Development research was used in this study. This study was divided into three stages: (1) qualitatively analyzing documents in the form of a review of relevant literature, then conducting field observations and interviews to rationalize the problem so that it can be used to create a gymnastic model; (2) The researchers developed a Si Buyung exercise model to improve gross motor skills in kindergarten students and created a questionnaire to be handed to experts as an instrument; (3) After the Si Buyung model was created, the researchers validated it with five experts using the Delphi technique. Result: The computation results revealed that the total content validity of each statement item is more than 0.79, indicating that all statement items meet the criteria. An average of 0.84 was attained overall. Conclusion: Based on Aiken's validity, the Si Buyung exercise model for improving gross motor skills in early childhood has a good score, indicating that the Si Buyung exercise model can be applied in early childhood.
