Strength training affects metabolism by increasing muscle mass, which in turn enhances the body's basal metabolic rate (BMR). A higher BMR means that the body burns more calories at rest, contributing to fat loss and improved body composition. Additionally, strength training can lead to the phenomenon of **excess post-exercise oxygen consumption** (EPOC), where the body continues to burn calories even after the workout has ended. This metabolic boost not only aids in weight management but also supports overall functional strength and endurance, benefiting daily activities and athletic performance.
