Strength training positively affects insulin sensitivity, which is essential for regulating blood sugar levels. By engaging in resistance exercises, muscles become more efficient at utilizing glucose from the bloodstream. Increased muscle mass from strength training enhances the body's ability to absorb and use insulin effectively, thereby minimizing chances of insulin resistance—a major factor in type 2 diabetes. Additionally, improved insulin sensitivity leads to better energy utilization, weight management, and reduced risk of chronic diseases. Thus, incorporating strength training into fitness regimes is vital for metabolic health.
