Promoting regular physical activity has become an increasingly important public health and educational priority in China. Under the broader policy framework of Healthy China 2030, physical activity is no longer treated merely as an individual lifestyle choice, but as a key component of national health development, disease prevention, and quality-of-life improvement (). The Healthy China Action (2019–2030) explicitly emphasizes the importance of improving physical fitness, promoting active lifestyles, and creating supportive environments for health behavior change (). In parallel, the provides population-specific recommendations and identifies regular movement, reduced sedentary behavior, and long-term persistence as core principles of physical activity promotion in the Chinese context. Together, these policies highlight a central concern for universities: how to help young adults develop sustainable exercise habits before they enter full adulthood (). Chinese college students represent a particularly important population for exercise promotion. University years are a transitional period during which students gain greater autonomy over their time, daily routines, social relationships, and health behaviors. In principle, this autonomy should create opportunities for regular physical exercise. In practice, however, many Chinese college students face academic pressure, examination demands, employment uncertainty, irregular schedules, digital entertainment, and uneven access to sport facilities or professional exercise guidance (; ). A systematic review of physical exercise among Chinese college students found that lack of time caused by academic pressure, limited facilities, and insufficient professional guidance are important barriers to exercise participation (). These findings suggest that the problem is not simply whether college students know that exercise is beneficial; rather, the more difficult issue is whether they can maintain exercise over time in the face of competing demands (; ). For this reason, exercise adherence is a particularly meaningful outcome in the university context. Compared with occasional exercise participation or general physical activity level, exercise adherence captures a more stable and behaviorally important question: whether students can persist in exercise despite difficulties, distractions, emotional fluctuations, and environmental barriers. In other words, the core challenge is not merely moving students from inactivity to activity, but helping them move from “wanting to exercise” to “sticking with exercise.” Recent research among Chinese college students has also treated exercise adherence as a psychologically meaningful health behavior. For example, examined exercise adherence in relation to peace of mind among Chinese college students, highlighting the relevance of adherence not only for physical health, but also for psychological wellbeing.
