Strength training enhances metabolic efficiency by increasing muscle mass, which in turn raises the basal metabolic rate (BMR). More muscle requires more energy, resulting in increased calorie burn even at rest. Additionally, strength training improves insulin sensitivity, helping the body regulate blood sugar levels more effectively. Enhanced metabolism contributes to better weight management and overall energy levels. Over time, strength training can lower the risk of chronic diseases and support better body composition, making it a crucial component of a well-rounded fitness routine.
