Metabolic syndrome is a cluster of conditions—including high blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels—that increase the risk of heart disease, stroke, and diabetes. Fitness plays a crucial role in preventing or managing this syndrome; regular exercise improves insulin sensitivity, helps control weight, and reduces blood pressure. Engaging in physical activity can mitigate these risk factors, highlighting the importance of a consistent fitness regimen in maintaining overall health.
