The study explored the views of primary care physicians on barriers to counseling patients with chronic diseases about physical activity, with regard to their own healthy exercise habits and knowledge of its benefits. She used a quantitative cross-sectional method with a questionnaire collecting sociodemographic data, data on obstacles, habits and knowledge. The majority of respondents (44.1%) have average healthy exercise habits and reported that 48.5% gained some knowledge at university and 54.0% now have some sufficient knowledge. According to them, the main barriers are the lack of time at work (average 3.4 ± 0.817) and patients' preference for pharmacological treatment (average 3.31 ± 0.790). Physicians' healthy exercise habits and knowledge are significantly related to their perception of these barriers. The study highlights the need to improve medical curricula, professional development, and healthy lifestyle support for physicians to better integrate physical activity recommendations into primary care.
