The first type of nudge strategy is mainly based on human unconscious system, which mainly includes changing the behavioral background and increasing the selectivity of exercise; changing the default options to promote active decision-making in exercise; initiating role models to increase the visibility of exercise. The second type of nudge is mainly based on human reflective thinking, allowing people to feel the motivation of behavior and then inspiring human behavior, which includes opening self-commitment to promote the durability of exercise; using descriptive social norms to promote the enthusiasm of exercise; making daily reminders to overcome the laziness of exercise; utilizing the selection framework to increase the availability of exercise; employing social influence strategies to improve something interesting of exercise. Based on those above, three issues needed to be explored in future research were suggested: at first, further testing the effectiveness of exercise nudge strategies; secondly, exploring the long-term effects of nudge intervention; thirdly, conducting joint research on exercise promotion based on Dual-System theory.
