Resistance training can significantly affect metabolism by increasing muscle mass, which in turn elevates resting metabolic rate. More muscle requires more energy to maintain, leading to increased caloric expenditure even at rest. This metabolic boost is particularly beneficial for weight management and can assist in fat loss. Additionally, resistance training improves insulin sensitivity and glucose metabolism, which are essential for preventing metabolic disorders. The increase in muscle tissue also enhances the body's ability to utilize stored energy efficiently. Thus, incorporating resistance training into a fitness routine can lead to long-term metabolic benefits and improved body composition.
