BACKGROUND: The increasing prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), parallels the rise in sedentary lifestyles. MASLD is the most common form of steatotic liver disease (SLD), which represents the umbrella beneath which the vast majority of chronic liver diseases fall, including alcohol-related liver disease and their overlap. These conditions are the leading contributors to chronic liver disease, significantly impacting global morbidity and mortality. Despite the emergence of new pharmacotherapies, exercise represents the foundation of MASLD treatment. OBJECTIVE: This review aims to provide an updated perspective on the role of exercise in the management of SLD, highlight its molecular and clinical benefits, and explore its benefits and safety in the stage of cirrhosis. METHODS: Evidence from pre-clinical and clinical studies was reviewed to evaluate the impact of exercise on SLD (mainly MASLD), advanced chronic liver disease stages, and its relevance in the context of evolving therapies such as Resmetirom and incretin-based anti-obesity medications. CONCLUSION: Exercise remains a cornerstone intervention in the management of MASLD, with suggested benefits even for patients who have progressed to cirrhosis. Personalized exercise regimens should be prioritized for all patients, including those receiving pharmacotherapy. Further research is needed to refine exercise protocols and investigate their impact on histologic and clinical outcomes, as well as their potential synergistic effects with emerging treatments.
