Physical activity (PA) promotion has become a central objective of Public Health Organisations, due to its long-lasting global benefits on health. The 2023 recommendations recommend at least 150 minutes of moderate physical activity or 75 minutes of intense physical activity per week for adults. New approaches focus on physical exercise as an integral part of daily life. Primary care doctors play a key role in promoting physical activity. Yet in 2010, only 30% of them advised their patients on PA. This is partly due to their own sedentary lifestyle, caused by heavy workloads, irregular working hours, lack of free time and insufficient institutional and financial support for promoting physical activity. An active doctor is an active patient, and the promotion of physical activity in the workplace should be supported by institutions.
