Although infected individuals must stop exercising, exercise is not prohibitedwhenwithout symptoms and complications. Whereas exercise can be effective in immune systemreinforcement during the prevention, recovery, and post-recovery stages, COVID-19-recovered Individuals (CRI) must exercise under accurate considerations. Objectives: This study aimed to study exercise in cold weather for the CRI. Methods: This article overviews how different exercises affect the immune system. PubMed, Science Direct, and Google Scholar Databases and keywords including cold weather, COVID-19, immune system, and combined exercise were used to access scientific articles. Results: Recent reports show that different sport sandexercises significantly improve COVID-19 symptoms, although there are many discrepancies among researchers in prescribing exercise programs (various training protocols, duration, and intensity). Also, CRIshould avoid exercise in cold weather due to breathing complicationsConclusions:Based on the present study, regular exercises (aerobic, resistance, and combined) with moderate intensity improve COVID-19 symptoms and the immune system.
