To the best of our knowledge, this is the first pilot trial study that incorporates self-efficacy theory, enhancing strategies, and blended methods to promote physical activity in pregnant women with high risk for GDM. Physical activity can prevent the incidence of GDM and improves health outcomes for pregnant women and their offsprings. This theory-guided, evidence-based, and blended physical activity intervention appeals to be delivered to a large number of participants. Additionally, this intervention is developed step by step under the guidance of the MRC framework. The present study provides an example of a process for intervention protocol development and pilot testing, and can also be applied as a learning reference for clinical research. Apart from that, this study may improve the cooperation of medicine, nursing, and sports. The study results will help to build normal procedures for the management of physical activity during pregnancy.This study has some limitations. The expert panel discussion was held online, which may cover some nonverbal communication [
